Which of the following is true of genes coding for tRNA? A. Segments coding for tRNAs are separated by short spacer sequences B. Are transcribed completely without modifications C. All of the above D. Each gene codes for one single tRNA molecule
Question
Which of the following is true of genes coding for tRNA? A. Segments coding for tRNAs are separated by short spacer sequences B. Are transcribed completely without modifications C. All of the above D. Each gene codes for one single tRNA molecule
Solution
The correct answer is D. Each gene codes for one single tRNA molecule.
Here's why:
A. Segments coding for tRNAs are separated by short spacer sequences - This is not always true. While some tRNA genes are separated by spacer sequences, others are found in clusters without spacer sequences.
B. Are transcribed completely without modifications - This is not true. tRNA molecules undergo extensive post-transcriptional modifications.
C. All of the above - Since both A and B are not entirely correct, this option is not correct.
D. Each gene codes for one single tRNA molecule - This is true. Each tRNA gene codes for a specific tRNA molecule that recognizes a specific codon on the mRNA.
