Question

Which process is part of transcription?

A.DNA is copied to create a second DNA strand.
B.mRNA codons and tRNA anticodons assemble amino acids.
C.DNA is unzipped with the aid of DNA polymerase.
D.mRNA is synthesized from a strand of DNA.

Answer 1

Answer:

C and D

Explanation:

mostly D coz C occurs in transcription as well as DNA replication

Answer 2

Answer:

Option D is the correct answer.

mRNA is synthesized from a strand of DNA.

Explanation:

It actually consists of two processes: transcription and translation. Transcription takes place in the nucleus. It uses DNA as a template to make an RNA molecule. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein.

Transcription is the first part of the central dogma of molecular biology: DNA → RNA. It is the transfer of genetic instructions in DNA to messenger RNA (mRNA). During transcription, a strand of mRNA is made that is complementary to a strand of DNA.
