Question 1

What is the order of DNA replication?

Answer 1

1. Transcription (DNA unzips into mRNA)
2. Translation (mRNA is read and a protein is made)

Answer 2

In the nucleus, the DNA gets unzipped and a copy of the DNA sequence is made.
This copy is a molecule called messenger RNA (or mRNA) and it’s the transcript that will be used to make the protein.

What is translation?

Answer 3

The mRNA, leaves the nucleus, and goes into the cytoplasm where it joins with the ribosomes, which read the copied code and begin to create proteins, placing one amino acid at a time in a specific order

G2. Preparation for mitosis

M. Cell division (mitosis)
