Worked Solution & Example Answer:Which statement about rRNA is true? A - Scottish Highers Biology - Question 1 - 2023
Step 1
Identify the true statement about rRNA
Answer
To determine which statement about ribosomal RNA (rRNA) is true, we need to evaluate each option:
- A. It contains deoxyribose: This statement is false because rRNA contains ribose, not deoxyribose. Deoxyribose is found in DNA.
- B. It has two strands: This statement is also false. rRNA is usually single-stranded, unlike DNA, which is double-stranded.
- C. It is a component of ribosomes along with protein: This statement is true. rRNA is a crucial component of ribosomes, where it plays a role in protein synthesis by facilitating the binding of mRNA and tRNA.
- D. It is not transcribed from DNA: This statement is false. rRNA is indeed transcribed from DNA, specifically from rRNA genes.
Thus, the correct answer is C.
