Question 10 of 13 Which statement best describes the process at Step 2 in the diagram?
DNA TACAAACGACCOTTC
ATGTTTGCTOOCAAG .
(1) DNA a template from which mRNA
(mengur RNA) is made
mRNA
AUGUUUGCUCOCAG
(2)
methionine phenylalanine alanin lycinely
(1 point)
A. An mRNA molecule signals which nucleotides should be joined to form a nucleic acid.
B. The codons of an mRNA molecule signal proteins to create a carbohydrate chain.
C. The genetic information coded in an mRNA molecule is translated into an amino acid chain.
D. A protein chain acts as a pattern for creating an mRNA molecule with the proper sequence.

The statement that best describes the process in step 2 of the diagram is the genetic information coded in an mRNA molecule is translated into an amino acid chain (option C).

Explanation:

The sequence of nitrogenous bases of mRNA serves to make each sequence of three nucleotides form a codon, which codes for a specific amino acid.  In the second step of the scheme, a chain of mRNA can be observed, whose triplets encode an amino acid, forming a small polypeptide.

Step one is the transduction of the DNA genome to form the messenger RNA.

The other options are not correct because:

    A. The mRNA does not indicate which nucleotide sequence forms a nucleic acid.

    B. mRNA chain codons encode amino acids, not carbohydrates.

    D. Proteins do not code to form mRNA, but DNA.
