Question
. Within a strand of RNA, nucleotides can contain one of four different nitrogenous bases. What is the impact of this variation in nitrogenous bases? (2 points)
a. The bases arrange themselves into codons consisting of three bases, with each codon producing a unique amino acid.
b. The different bases code for different amino acids, which build proteins with a wide variety of functions.
c. The nitrogenous bases all form the same types of bonds, and therefore differ in structure but not chemical properties.
d. The variations in base sequence require a greater number of proteins to carry out RNA translation.
Explanation / Answer
The RNA strand consists of nucleotides which has one or four different nitrogenous bases. Each nitrogenous bases codes for an aminoacid and together buid a protein.
the correct option is A. The bases arrange themselves into codons consisting of three bases, with each codon producing a unique amino acid.
for example: *Methionine is the amino acid which always code with AUG nitrogenous base.
*Tryptophan is the amino acid which always code with UGG nitrogenous base.
