9. Summarize how transcription makes mRNA. A complete answer will include: gene, mRNA, sequence, nucleotides, complementary, RNA polymerase, base-pairing rules.
Answer:
Explanation:
Transcription is the first step in gene expression, in which information from a gene is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go through some processing steps before translation into proteinsThe main enzyme involved in transcription is RNA polymerase, which uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an RNA strand in the 5' to 3' direction, adding each new nucleotide to the 3' end of the strand.Transcription of a gene takes place in three stages: initiation, elongation, and termination. Here, we will briefly see how these steps happen in bacteria. You can learn more about the details of each stage (and about how eukaryotic transcription is different) in the stages of transcription article.
Initiation. RNA polymerase binds to a sequence of DNA called the promoter, found near the beginning of a gene. Each gene (or group of co-transcribed genes, in bacteria) has its own promoter. Once bound, RNA polymerase separates the DNA strands, providing the single-stranded template needed for transcription.Elongation. One strand of DNA, the template strand, acts as a template for RNA polymerase. As it "reads" this template one base at a time, the polymerase builds an RNA molecule out of complementary nucleotides, making a chain that grows from 5' to 3'. The RNA transcript carries the same information as the non-template (coding) strand of DNA, but it contains the base uracil (U) instead of thymine (T). [What do 5' and 3' mean?]Termination. Sequences called terminators signal that the RNA transcript is complete. Once they are transcribed, they cause the transcript to be released from the RNA polymerase. An example of a termination mechanism involving formation of a hairpin in the RNA is shown belowIn bacteria, RNA transcripts can act as messenger RNAs (mRNAs) right away. In eukaryotes, the transcript of a protein-coding gene is called a pre-mRNA and must go through extra processing before it can direct translation.
Eukaryotic pre-mRNAs must have their ends modified, by addition of a 5' cap (at the beginning) and 3' poly-A tail (at the end).
Many eukaryotic pre-mRNAs undergo splicing. In this process, parts of the pre-mRNA (called introns) are chopped out, and the remaining pieces (called exons) are stuck back together.
End modifications increase the stability of the mRNA, while splicing gives the mRNA its correct sequence. (If the introns are not removed, they'll be translated along with the exons, producing a "gibberish" polypeptide.)

Transcription is the process of making an RNA copy of a gene sequence. This copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes.
Transcription occurs in three steps—initiation, elongation, and termination.
What are the three roles of RNA polymerase in transcription?
Eukaryotic cells contain three distinct nuclear RNA polymerases that transcribe distinct classes of genes.
Protein-coding genes are transcribed by RNA polymerase II to yield mRNAs, ribosomal RNAs (rRNAs) and transfer RNAs (tRNAs) are transcribed by RNA polymerases I and III.
Thus, this is the summary of the transcription.

Which of these is the direct result of an error in the transcription of a DNA nucleotide
Amino acids do not bond to tRNA.
The nuclear membrane is ruptured.
A codon sequence is incorrect.
Transportation of mRNA does not occur.
The direct result of an error in the transcription of a DNA nucleotide is that a codon sequence will be incorrect. So the correct option is C.
What is transcription?The first step in the expression of a genetic code is called transcription. During gene expression, the information stored in the DNA is expressed in the form of proteins.
In transcription, DNA is utilized to produce RNA. The RNA molecule is the copy of the DNA's genetic sequence. The RNA copy produced by the process of transcription is called an RNA transcript.
This transcript has the required information for the construction of a polypeptide chain. But before the formation of proteins, a eukaryotic RNA transcript requires processing to be converted into mRNA.
The mRNA thus produced has codons for the formation of proteins. Each amino acid is a result of the translation of three codons.
Therefore, if there is an error in the transcription of DNA nucleotides, the codon sequence will be incorrect. The correct option is C.

How do natural pollination and artificial pollination differ
Answer:
Natural pollinators, like bees, pollinate flowers randomly, essentially mixing up their genomes and increasing genetic diversity. This leads to different types of future plants. However, artificial pollination is so labor intensive, it's hard to replicate the same variety in pollination.Aug 8, 2017
Explanation:
Artificial pollination is the type of pollination carried out by humans. It is a mechanical technique used to pollinate plants when natural pollination is insufficient or undesirable. It does not require the help of insects or weather.
Natural pollination consists of the transfer of pollen between the male and female organs of the flowers, without human intervention. In other words, pollen is transferred from the stamens to the stigma of the flowers, where it fertilises the ovules, making seed and fruit production possible.

The oceans have become increasingly acidic in recent years as the water absorbs more and more carbon dioxide
from the atmosphere. This increased acidity interferes with the ability of corals to maintain their skeletons. In
addition, an increase in water temperatures worldwide is causing coral bleaching, another condition that threatens
the health of coral reefs.
Based on this information, which of the following would most improve the health of coral reefs?
Reducing the use of fossil fuels since they emit CO2 that reacts in water
CO2+H2O-->H2CO3
The following would most improve the health of coral reefs is reducing the use of fossil fuels.
What kills corals?One of the biggest threats to coral reefs is the so-called "coral bleaching", a process that leads to the death of hundreds of corals around the world. The phenomenon occurs when the temperature of the water increases, due to natural causes, such as El Niño, or caused by man, such as global warming.
Scientists have created a device that innovates the technique of transplanting corals from the recovery of fragments with tissue loss. The device works as a kind of cradle, where the fragments are kept until they recover and grow.

Donald is trying to get through a door but his friend Goofy is blocking the way using 15 N of force. Donald finally pushes on the door with 20 N and gets through knocking Goofy out of the way. Solve for net force.
Answer:
5 N
Explanation:
Goofy is blocking the way with 15 N force and Donald was only able to knock Goofy off using a 20 N force. The net force would be the difference between the applied force of Donald and that of Goofy.
Hence,
20 N - 15 N = 5 N
The net force is, therefore, 5 N.

How long can water remain stored in a confined aquifer?
millennia
a few days
more than a million years
several years
It will take several years to store water in a confined aquifer.
What is confined aquifer?An aquifer that is enclosed and contains a lot of water is called a confined aquifer. The aquifer is under pressure because of layers of impermeable material that are both above and below it.
As a result, when the aquifer is pierced by a well, the water will rise above the aquifer's surface.
An aquifer with a water table, also known as an unconfined aquifer, has its upper water surface at atmospheric pressure, allowing it to rise and fall.
Due to their typical proximity to the Earth's surface, water table aquifers are affected by drought conditions earlier than restricted aquifers.
Therefore, It will take several years to store water in a confined aquifer.
