How would a bacteria explore a non-coding portion of DNA?​

Answers

Explanation:

Non-coding DNA sequences are components of an organism's DNA that do not encode protein sequences. Some non-coding DNA is transcribed into functional non-coding RNA molecules (e.g. transfer RNA, ribosomal RNA, and regulatory RNAs). Other functions of non-coding DNA include the transcriptional and translational regulation of protein-coding sequences, scaffold attachment regions, origins of DNA replication, centromeres and telomeres. Its RNA counterpart is non-coding RNA.

The amount of non-coding DNA varies greatly among species. Often, only a small percentage of the genome is responsible for coding proteins, but an increasing percentage is being shown to have regulatory functions. When there is much non-coding DNA, a large proportion appears to have no biological function, as predicted in the 1960s. Since that time, this non-functional portion has controversially been called "junk DNA".[1]

The international Encyclopedia of DNA Elements (ENCODE) project uncovered, by direct biochemical approaches, that at least 80% of human genomic DNA has biochemical activity, which they defined as being transcribed, a definition not shared with most other biologists.[2] Though this was not necessarily unexpected due to previous decades of research discovering many functional non-coding regions,[3][4] some scientists criticized the conclusion for conflating biochemical activity with biological function.[5][6][7][8][9] Estimates for the biologically functional fraction of the human genome based on comparative genomics range between 8 and 15%.[10][11][12] However, others have argued against relying solely on estimates from comparative genomics due to its limited scope.[citation needed] Non-coding DNA has been found to be involved in epigenetic activity and complex networks of genetic interactions and is being explored in evolutionary developmental biology.[4][11][13][14]

Are the four daughter cells produced by meiosis identical or unique?

Answers

Answer:

i think it's meiosis identical but im not sure please tell me if it's right or not

Answer:

[tex]\boxed {\boxed {\sf Unique \ daughter \ cells}}[/tex]

Explanation:

There are two main types of cell division: mitosis and meiosis. Mitosis makes identical cells for growth and repair.

On the other hand, meiosis is used for sexual reproduction.

In this reproduction, one diploid cell produces 4 haploid gametes/sex cells, meaning they have half of the genetic information. This is so during fertilization, when a sperm and egg combine, the zygote will have a full set of chromosomes.

One of the most important parts of meiosis is called crossing over. In this step, the chromosomes exchange information and create totally unique chromosomes.

This is one reason why siblings, aside from identical twins, can look similar, but not identical!

Lactase is an enzyme that many different animals have that helps digest the sugar lactose Why can this enzyme be the same in different species?

0 Lactase is necessary for survival of all organisms

0 All living things share a common code-DNA

0 Lactase is not regulated by external environments.

It is not possible for it to be the same in different species

Answers

Answer:

All living things share a common code-DNA

Explanation:

Enzymes are proteinous substances, which like every other proteins are encoded by a genes. In the expression of these genes, a set of codons (three nucleotide base) called GENETIC CODE is used. ONE of the characteristics of this genetic code is that it is NEARLY UNIVERSAL meaning that the same genetic code is used by virtually all known living organism.

According to this question, lactase enzyme, which helps digest lactose sugar in organisms, is the same in different organisms. This is due to the fact that all living things share a common code-DNA e.g AUG codes for methionine in all organisms, hence, when these DNA undergoes expression, it yields the same products in different organisms.

what provides new variation

Answers

Answer:

Mutation

Explanation:

The main cause of variation within a population is usually through genetic mutation.

Mutation is the alteration of the genetic sequence within an organism. It often lead to formation of new genetic patterns and codes.

Most times, environmental influences are paramount to causing genetic mutation within a population.

Other times, it might be due to competition and some other internal factors.

Mutation can be transferred from parents to offspring in most cases.

how does the concept of apoptosis relate to sally cancer cells compared with normal cells ?

Answers

Answer:

Apoptosis is defined as a programmed cell death and plays very important role in the removal of cancerous cells. Apoptosis is the process in which cell undergoes several processes and attempt sui-cide. Apoptosis do not cause any harm to human cells as it removes only unwanted cell.

Apoptosis can prevent cancerous cells by telling unwanted growth of cell to self destruct. Cancer cells are formed due to proliferation of cells and ignore the signals of self destruction to prevent apoptosis.

In Sally's case also, cancer cells ignored the signal of apoptosis and a tumor was found in her colon.
