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

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.

well

explanation:

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
