Question

What are the necessary components required to start the transcription of a gene? What needs to be added in order to create a protein?

Answer 1

RNA polymerase is the main transcription enzyme.

It begins when RNA polymerase binds to a promoter sequence near the beginning of a gene.

It has two stages: transcription and translation.

Answer 2

Hope this helps: From the test.

Step-by-step explanation:

The RNA polymerase and positive transcription factor start the transcription into mRNA. The Ribosomes are necessary to produce a protein.

The longer the length of the transcribed region, the longer the gene (DNA) will be.

This DNA would be eliminated by using one of the two mRNA destroyers. These help to eliminate the gene after it has been produced.

The negative transcription factor works in the regulatory region and it inhibits the RNA polymerase from acting.

There are more than one positive transcription factors in order to get different protein shapes.

Part 2

To maximize the rate of transcription from the gene, there should be a high affinity for both the positive transcription factor and the RNA polymerase. At the same time, the negative transcription factor must have a low affinity for the DNA.

When this happens, there are a lot of positive transcription factors but the RNA polymerase doesn't have a high rate of bonding to the regulatory region to produce a strand of DNA.

In order to minimize the rate of transcription, you should create a low concentration of the positive transcription factor, a low affinity for RNA polymerase, and a high affinity and concentration of the negative transcription factor.

Part 3

The greener the cell, the higher the protein level in the cells.

A.High

B.Low

C.High

D.High

E.Slow

The cells would turn from green to grey because they would not be producing any protein.
