What is going on in this image?

The image shows the transcription process in which mRNA is being synthesized. DNA double strands open in the transcription bubble and RNA polymerase acts there to add the correct nucleotides.

<h3>What is transcription?</h3>

In protein synthesis, the first step is to synthesize messenger RNA, mRNA.

Transcription is the coping process of the DNA section, occurs inside the nucleus membrane, and uses fragments of DNA molecules to do it.

During transcription, the DNI molecule separates into two strands to form the transcription bubble. At this point, two strands can identify, the coding strand and the template strand.  

  • The coding strand goes in direction 5' to 3' and carries the same nucleotides as mRNA, except for thymine which is replaced by uracyl in the RNA molecule.

  • The template -complementary- DNI strand is read in direction 3´→ 5´ to build the mRNA molecule in direction 5´→ 3´.

While growing, the mRNA strand complements the DNA template strand. Bases complementation is as follows,

  • Adenine pairs DNA Thymine
  • Uracyl pairs DNA Adenine
  • Guanine pairs Cytosine
  • Cytosine pairs Guanine

The enzyme RNA polymerase reads the original DNI strand to add the correct nucleotides during mRNA synthesis.

Once transcription is over, mRNA moves to the cytoplasm to begin the translation process.

In the image we can see

1) the DNA molecule at the left. We can differenciate the template strand from the coding one.

2) the transcription bubble and RNA polymerase acting there.

3) Growing mRNA which complements the template strand

4) Available free nucleotides which are added to the polymere

HELP ME!! which of the following statements about energy is true?
hjlf
Option A. Glucose is made from ATP and this is done so in the cytoplasm during glycolysis. Chloroplasts capture light energy from the sun and use it to make glucose, not ATP.

You are given an experimental problem involving control of a gene's expression in the embryo of a particular species. One of you
adell [148]

Answer:

B) You measure the quantity of the appropriate pre-mRNA in various cell types and find they are all the same.

Explanation:

In the above scenario, we are using the control gene and we should know about the control gene is that its expression is either at transcription level or at translation level. For this situation we should examine the pre-mRNA stage of control gene in various cells because it is control gene so it should be present in various cells.

So, the best practice is to quantify the pre-mRNA level of gene then we can effectively solve the experimental problem and find the gene expression either it is at transcription or translation level.
