The sequence of nucleotides found in mRNA is determined by the
a) structure of DNA polymerase,
b) sequence of amino acids in a protein,
c) large complex proteins,
d) sequence of nucleotides in a gene,
e) fatty acids and glycerol in the cell.
The ribosome is needed for translation of mRNA
(a) because it has the enzyme for adding amino acids to the 5’ end of a tRNA (b) because the ribosomal RNA contains the codon which determines the sequence of amino acids in a protein (c) because it positions tRNA and mRNA so that correct pairing of codon and anti-codon can occur (d) because it has an enzyme that removes introns from mRNA (e) all of the above
What is the role of transcription in the determination of the amino acid sequence of a polypeptide chain?
A.
It pairs anticodons and codons.
B.
It synthesizes an mRNA strand.
C.
It duplicates the information in DNA.
D.
It decodes the information from mRNA.
