Question

The diagram below is a model of the process of transcription.
What is the purpose of strand B?

a) To act as a template for the synthesis of messenger RNA
b) To carry the code from the DNA molecule in the nucleus to the ribosome
c) Delivers specific amino acids to the ribosome to make proteins
d) Transfers nucleic acids to the nucleus

Answer 1

Answer:

b

Explanation:

The purpose of the strand B be would be to carry the code from the DNA molecule in the nucleus to the ribosome.

Looking closely at the diagram, strand B is the strand of RNA that is still in the process of being synthesized while strand A is acting as the template. The function of the RNA strand is primarily to carry an encoded message in the DNA molecule from the nucleus to the ribosome in the cytoplasm where the genetic codes would be translated during the process of protein synthesis.

The correct option is, therefore, b.

Answer 2

The purpose of strand B would be to carry the code from the DNA molecule in the nucleus to the ribosome (option b)

The strand B shown in the figure represent the RNA transcript derived from the transcription process due to the presence of uracil which is always found in RNAs.

After undergoing a series of processes including transcriptional control, they become mRNA and are transported to the ribosome to undergo translation to proteins.
