The diagram is a model of transcription

What is the purpose of strand B?

- To carry the code from the DNA molecule in the nucleus to the ribosome

- Delivers specific amino acids to the ribosome to make proteins

- Transfers nucleic acids to the nucleus

- To act as a template for the the synthesis of messenger RNA

In the process of transcription, how does the mRNA strand relate to DNA? (6C)

Question options:

The mRNA strand mimics the DNA strand; however, uracil is the 5th based used in the sequence.  

The mRNA strand is complementary to the DNA strand; however, uracil instead of adenine is paired with thymine.  

The mRNA strand is an exact copy of the DNA strand.  

option a and d is the correct answer

i hope this u
