DNA Replication Concepts and Processes

To destroy old DNA

To change the genetic code

To ensure each new cell has a complete set of DNA

To create more proteins

It joins the DNA strands together

It acts as a proofreader

It unzips the DNA double helix

It adds nucleotides to the DNA strand

Helicase

DNA ligase

DNA polymerase

RNA polymerase

It unzips the DNA strands

It joins the DNA strands

It synthesizes RNA

It proofreads and corrects errors

It unzips the DNA strands

It adds nucleotides to the DNA strand

It proofreads the DNA

It joins the new and original DNA strands

Each new DNA molecule has one original and one new strand

DNA replication occurs only once

The original DNA molecule remains unchanged

Each new DNA molecule has two new strands

By unzipping the DNA strands

By joining the DNA strands

By proofreading and correcting errors

By synthesizing RNA

The error leads to a mutation

The error is corrected by DNA ligase

The error is ignored

The error is corrected by DNA polymerase

Unzipping the DNA double helix

Adding nucleotides to the DNA strand

Proofreading the DNA

Correcting errors in the DNA

One new DNA molecule with two new strands

One new DNA molecule with two original strands

Two identical DNA molecules, each with two new strands

Two identical DNA molecules, each with one new and one original strand
