Q

transcription

A

To get from gene to protein, the cell produces an intermediate molecule called messenger RNA (mRNA) in a process called Taking dna and copying it to make rna

Q

translation.

A

The cell then uses this mRNA to produce a protein in a process called Taking mrna turning into protein Done by ribosome

Q

similarities and differences we see here between prokaryotic cells and eukaryotic cells

A

There is retention of the basic process of protein production, BUT There are differences in cellular organisation at both the micro and macro scale.
