Question

Solution
The correct answer is e "A" and "C".
Explanation:
a. RNA is single stranded - This is true. Unlike DNA, which is double-stranded, RNA is a single-stranded molecule in many of its biological roles and has a much shorter chain of nucleotides.
b. RNA includes the nucleotides A, T, G, and C - This is false. RNA includes the nucleotides Adenine (A), Uracil (U), Guanine (G), and Cytosine (C). In RNA, Uracil replaces the Thymine found in DNA.
c. RNA is involved in protein synthesis - This is true. RNA is vital for protein synthesis in the cell. In this process, mRNA (messenger RNA) carries the genetic information from the DNA to the ribosomes, which then translate this information into specific proteins.
So, the statements "RNA is single stranded" and "RNA is involved in protein synthesis" are true.
