Quick Answer: When The Cell Divides Where Does The Extra DNA Come From?

Where does DNA replication occur?

DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes.

Regardless of where DNA replication occurs, the basic process is the same.

The structure of DNA lends itself easily to DNA replication.

Each side of the double helix runs in opposite (anti-parallel) directions..

What is the section of DNA being copied called?

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).

What happens to DNA every time a cell divides?

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. … Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell.

Why is DNA duplicated well before cell division?

Before a cell divides, its DNA is replicated (duplicated.) Because the two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partner.
