Question
The DNA strand that is read to make RNA.
Group of answer choices:
- lagging strand
- leading strand
- nontemplate strand
- coding strand
- template strand
Solution
The DNA strand that is read to make RNA is known as the template strand. During the process of transcription, the RNA polymerase enzyme uses the template strand to synthesize a complementary RNA strand. The template strand provides the necessary sequence information for creating the RNA molecule, which ultimately translates into proteins during translation.
To clarify the significance of this terminology:
- Coding Strand: Also known as the nontemplate strand, it has the same sequence as the RNA transcript (except that it has thymine (T) instead of uracil (U)).
- Template Strand: The strand that RNA polymerase reads to synthesize RNA, thus it serves as the actual template for the nucleotide sequence of the RNA.
Overall, the correct answer to the question is the template strand.
