Answer 1

Answer:

a) Particular codons are generated in predictable ratios with random RNA polymers containing specific ratios of different nucleotides.

b) Poly(A) RNA directs the synthesis of only polylysine in vitro.

d) The codon table was completed by using RNA polymers of defined sequences.

Explanation:

A polynucleotide molecule is defined as the biopolymer which is composed of thirteen nucleotide monomers or more monomers which is covalently bonded in the chain.

While using the synthetic polyneuclitide in the cracking of the genetic code, the translation of a [tex]\text{poly(A) RNA tail}[/tex] that results in synthesis of the poly-lysine in the lab.

Some of the particular codons are produced by some specific ratios of a different nucleotides. This can be present in the different RNA polymers. Codon table includes the RNA polymers that contains nucleotides in some specific ratios.

Thus, the options (a), (b) and (d) are correct.

In the population of plant K, each plant has only red flowers or only white flowers. A farmer collected the seeds from plant K with red flowers to grow new plants. Explain why the new plants will have only red flowers

Answers

Answer:

nose

Explanation:

nosenosenosenosenosenosenosenosenosenosenose

The new plants will have only red flowers because the trait for red flowers is determined by a dominant gene, and all the plants in population K have the same homozygous genotype for the flower color.

In genetics, the flower color trait in population K is determined by genes present in the plants' DNA. There are two alleles, or gene variants, for the flower color: one for red flowers (let's call it R) and one for white flowers (let's call it r). The gene for red flowers (R) is dominant, meaning that even if only one copy of the gene is present in an individual's genotype (heterozygous), it will produce the red flower phenotype. On the other hand, the gene for white flowers (r) is recessive, which means it will only produce the white flower phenotype if two copies are present in the genotype (homozygous recessive).

In population K, all the plants have only red flowers, indicating that they must have the genotype RR. Since all the plants are homozygous for the dominant red flower gene (RR), when they reproduce, they can only pass on the dominant allele R to their offspring. As a result, all the new plants that grow from the seeds collected from these plants will also have the genotype RR and, therefore, express the red flower phenotype.

Since there are no plants in population K with the genotype rr (homozygous recessive), which is necessary for white flowers, there is no chance of white-flowered plants appearing in the new generation. Thus, the new plants will have only red flowers due to the uniformity of the homozygous dominant genotype in the original population.

What is transcription?

In genomics, transcription is the method of generating an RNA copy of a gene's DNA sequence. This copy, known as messenger RNA (mRNA), transports the protein information encoded in the gene's DNA.

This RNA copy, known as messenger RNA (mRNA), contains the genetic information required for a cell to produce proteins.

It transports information from the cell's nucleus to the cytoplasm, where proteins are produced.

The entire gene is copied into a pre-mRNA, which includes exons and introns, during transcription. Introns are removed and exons are joined to form a contiguous coding sequence during the RNA splicing process.

Thus, as the introns are getting removed completely, the mRNA sequence for the given DNA sequence will be: AUG GCA UAU UUU UUA AUU GAA UCU GCA CGA GAA AAU GAA GCA ACU UAG.

A researcher dried a feedstuff and determined that it contained 10 percent moisture. he took 1 gram (dry) of it and combusted it in the bomb calorimeter. the calorimeter contains 1 kg of water. The temperature was raised 2.7 degrees centigrade. Two kilograms (2000 grams) of dry matter of the material was fed to a pig each day for several days. the fecal collections of the pig averaged 200 grams dried per day for the last few days. the feedstuff analyzed 2.41 percent nitrogen (dry basis); the feces (dry basis) analyzed 4.6 percent nitrogen. (hint: the feedstuff contained _____ grams protein, the feces contained _____ grams protein.)

Answers

Answer:

Explanation:

The objective of the information given is to calculate the apparent digestible dry matter present in the feedstuff(%) and the apparent digestibility of the protein?

From the given information:

The apparent digestible dry matter present is:

[tex]=\dfrac{ (\text{Dry matter fed to the pig} - \text{Fecal matter of the pig} )}{\text{Dry matter fed to the pig}} \times 100 \%[/tex]

where;

Dry matter fed to the pig = 2kg = 2000 g

Fecal matter of the pig = 200

The apparent digestible dry matter present = [tex]\dfrac{2000-200}{2000}\times 100\%[/tex]

[tex]=\dfrac{1800}{2000}\times 100\%[/tex]

= 90

Amount of Nitrogen(i.e. the protein) content present in the feedstuff = 2.41%

i.e.

2.41 g/100 g   OR   48.2 g/2000 g feed

Amount of protein present in feces = 4.6% (4.6 g/100 g  OR  9.2g/200g of feed)

apparent digestibility of the protein is:[tex]=\dfrac{\text{Amount in feed }- \text{Amount in feces}}{\text{Amount in feed }}\times 100[/tex]

[tex]= \dfrac{(48.2 - 9.2)}{48.2}\times 100[/tex]

[tex]= \dfrac{39}{48.2}\times 100[/tex]

= 81%

Decomposers can recycle dead plants and animals into chemical nutrients such as carbon and nitrogen that are released back into the soil, air and water as food for living plants and animals.

Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.

Decomposers, such as bacteria, fungi, termites, and earthworms, are scavengers that feed on the organic material found in dead producers and consumers. They break down the organic material to the nutrient level. Nutrients in soils are essential for producers to grow. Nutrients include nitrogen, carbon, and phosphorous. Thus, dead consumers (and producers) are recycled back into new producers.

Some experts attribute the increase in ADHD diagnoses to an increased awareness of the disorder, while others attribute the increase to ______ diagnoses.

Answers

Answer:

incorrect

Explanation:

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders affecting children. ADHD is characterized by different behaviors that include one or more of the following symptoms: inattention (poor concentration), impulsivity (interrupting behavior) and hyperactivity (state abnormally active). It has been reported that DHD diagnoses in children between 4 and 17 years of age dramatically increased from 6 percent (6%) during the period 1997-1998 to 10 percent (10%) during the period 2015-2016. Although the causes of this increase have not been established, the American Psychiatric Association (APA) indicates that the increase might be due to the increased access of communities historically relegated to receive care and decreased stigma to be diagnosed with ADHD. Other possible causes range from chemical factors to unhealthy habits during pregnancy (e.g., smoking, substance abuse, poor nutrition). On the other hand, it has also been proposed that this increase may be as a result that ​ADHD is often misdiagnosed and confused with other conditions (e.g., bipolar disorder, autism, kids being kids, etc).

b) In how many cases would you fail to know the first two nucleotides of the codon if you knew which amino acid is specified by it?

Answers

Answer:

b)  3 cases

Explanation:

a) From the table of genetic codes, there are 28 codons that specify more than one amino acid assuming only the first two nucleotides are considered. In these cases, one cannot outrightly specify the amino acid the genetic codes are coding for without knowing the last nucleotide of the codes. For example, UU can be for Phenylalanine or Leucine, CA can be for Histidine or Glutamine, etc.

b) From the table of genetic codes, the first two nucleotides of Arginine can be either of CG or AG, that of Serine can be either of UC or AG while that Leucine can be either of CU or UU. Only in these 3 cases would one fail to know which are the first two nucleotides assuming the name of the amino acids are given.

This animal has a protostome developmental pattern and a trochophore larva. Identify the major clades that this animal belongs to

Answers

Answer:

Lophotrochozoans (it is a protostome)

Explanation:

Lophotrochozoa is a group (clade) of protostome animals, i.e. animals that undergo a developmental pattern in which the blastopore develops into the mouth. Lophotrochozoa clade includes bryozoans, annelids, molluscs, brachiopods, and platyhelminthes. Most lophotrochozoans have either a lophophore or trochophore larvae during the planktonic stage. A trochophore larva is a marine planktotrophic larva with several bands of cilia that form the locomotory organ (i.e., the prototroch), which is only found within the Lophotrochozoans.

When the larva and the adult form of an organism are different from each other this type of development is called indirect development. For example Porifers and platyhelminthis.

Answers

Answer:

A)Como Juan nació normal (aa) la única posibilidad para que Santiago su hijo naciera con polidactilia era que su madre lo fuera también.

Explanation:

La polidactilia es una malformación causada por un alelo dominante asociada con al aparición de más de 5 dedos en cada pie o más de 5 dedos cada mano. Un alelo dominante es una variante génica capaz de enmascarar la expresión de un alelo recesivo en individuos heterocigotos, es decir, en individuos portadores de una copia del alelo dominante y una copia del alelo recesivo para un gen en particular. De este modo, un alelo dominante es por definición aquel que será expresado en el fenotipo, con lo cual el único modo en el cual Santiago sea portador del alelo dominante causante del rasgo "polidactilia" es que él lo haya heredado, ya sea del padre o de la madre (es importante aclarar que también el alelo dominante puede haber surgido por mutación en la línea germinal). En este caso sabemos de acuerdo al enunciado que el padre de Santiago no tiene polidactilia y por lo tanto no es portador del alelo dominante, con lo cual se espera que Santiago haya heredado esta condición de su madre.
