The answer is B.Normal vision and Vitamin A
Answer:
Transcription
Explanation:
This occurs in three steps itself: initiation, elongation, and termination
Initiation (beginning)
- RNA polymers bind to a promoter on a gene
- DNA then unwinds to be "read" by an enzyme
- DNA now ready to make mRNA strand
Elongation (Second step)
- nucleotides are added to mRNA strand
- mRNA molecule is built after RNA polymers reads the DNA that unwound
- adenine (A) in DNA connects to a uracil (U) of RNA while connected to each other
Termination (End)
- RNA will cross a stop sequence in the gene (termination)
- mRNA done and disconnects or detaches from DNA
