Question

which statement best summarizes what happens during transcription?
a dna template is used to create an mrna strand.
an mrna template is used to create a dna strand.
a dna template is used to create a ribosome.
an mrna template is used to create a trna strand.

Explanation:

Transcription is a key step in gene expression where genetic information from DNA is copied into messenger RNA (mRNA). The DNA strand acts as the template for synthesizing a complementary mRNA strand, which then carries the code to the ribosomes for translation. The other options describe processes that do not match transcription: using mRNA to make DNA is reverse transcription, DNA does not make ribosomes directly in transcription, and mRNA does not template tRNA creation in this process.

Answer:

A. A DNA template is used to create an mRNA strand.
