The process of obtaining a copy of the information in a gene as a strand of messenger RNA is called
A) polymerase.
B) expression.
C) transcription.
D) translation.
The site where RNA polymerase attaches to the DNA molecule to start the formation of an RNA molecule is called a(n)
A) promoter.
B) exon.
C) intron.
D) enhancer.
You are provided with a sample of aardvark DNA. As part of your investigation of this DNA, you transcribe mRNA from the DNA and purify it. You then separate the two strands of the DNA and analyze the base composition of each strand and of the mRNA transcripts. You obtain the following results:
Which strand of the DNA is the "sense" strand that serves as the template for mRNA synthesis?
