DNA Replication

Front

After DNA replication is completed, what does each new DNA double helix consist of?

Back

Each new DNA double helix consists of one old DNA strand and one new DNA strand.

Front

Synthesis of a new DNA strand usually begins with:
- RNA primer
- DNA primer
- Okazaki fragment
- DNA ligase

Back

RNA primer

Front
