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 the process in which a DNA template is used to synthesize an mRNA strand. This occurs in the nucleus. Option B is incorrect as it's the reverse of transcription (which would be reverse - transcription in some cases but not normal transcription). Option C is wrong because ribosomes are made of rRNA and proteins, not directly from a DNA template in the way described. Option D is incorrect as tRNA is not made from an mRNA template during normal transcription.

Answer:

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