Answer:
The correct terms used interchangeably to refer to the strand of DNA that serves as the template for mRNA synthesis during transcription are:
a. Sense strand
b. Antisense strand
Therefore, the correct options are A and B.
Step-by-step explanation:
The sequence that directly corresponds to the mRNA product is represented by the sense strand, which is interchangeable with the coding strand.
On the other hand, during transcription, the antisense strand acts as a template, and the complementary mRNA is synthesised using its sequence. The names "mRNA strand" and "Crick strand," which are options c and d, are not frequently used to refer to the DNA template during transcription.
Understanding the flow of genetic information during gene expression depends on the precise identification of the sense and antisense strands.
Therefore, the correct options are A and B.
Your question is incomplete, most probably the complete question is:
"What are the terms used interchangeably to refer to the strand of DNA that serves as the template for mRNA synthesis during transcription? Select the appropriate term from the options:
a. Sense strand
b. Antisense strand
c. mRNA strand
d. Crick strand
