Ture or false: DNA replication is a semi-conservative process?

True

2
New cards

What does semi-conservative process mean?

When the DNA double helix splits and the 2 strands replicate. After replicating, each of 2 DNA molecules have 1 parental strand and one newly synthesized strand.

3
New cards

What are the building blocks of replication?

Triphosphate nucleosides

  • A, G

  • T. C

New cards

What is DNA Polymerase and what does it do?

It is an enzyme that builds the new DNA strand by adding triphosphate nucleotides to the growing strand according to the template

What is primase?

An enzyme that makes short RNA primers, which provide the starting point for DNA polymerase to begin adding nucleotides

What are initiator protein enzymes?

  • Proteins that recognize and bind to the origin of replication on the DNA

  • Unwind the double helix, allowing other replication proteins and enzymes to begin the replication process
