Question

Which occurs during transcription?

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

Answer 1

mRNA is synthesised from a strand of DNA.

this messengerRNA then carries the section of code from the DNA to a ribosome where it is transcribed into a protein.

Answer 2

Answer;

mRNA is synthesized from a strand of DNA

During transcription mRNA is synthesized from a strand of DNA.

Step-by-step explanation;

Transcription is the process that takes place in the nucleus of a cell, where DNA molecules acts as a primer to synthesis messenger RNA, catalyzed by the enzyme RNA polymerase.

It is the first step of expression of gene, a particular segment of DNA is copied to mRNA by RNA polymerase.

Then the mRNA is transported to the cytoplasm for the process of translation in which proteins are formed.
