BIO 1305 DNA Replication

Front

What is the Origin of Replication (Ori)?

Back

The specific DNA sequence where DNA replication begins.

Front

How do you build a complementary DNA strand from a template?

Back

For the template strand 5'-AAT CAT GGA-3', the complementary strand is 3'-TTA GTA CCT-5'.

Front

What is the role of DNA Polymerase delta in eukaryotes?

Back

It synthesizes the lagging strand during DNA replication.

Front

In which direction is DNA synthesized during replication?

Back

DNA is synthesized in the 5' to 3' direction.

Front

In which direction is the DNA template read during replication?

Back

The DNA template is read in the 3' to 5' direction.

Front

What type of bond joins nitrogenous bases in DNA?

Back

Hydrogen bonds.

Front

What is the function of a primer in DNA replication?

Back

A primer provides a starting point for DNA synthesis.

Front

What is the difference between leading and lagging strands?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short segments.

Front

What is the role of helicase in DNA replication?

Back

Helicase unwinds the DNA double helix at the replication fork.

Front

What are Okazaki fragments?

Back

Short segments of DNA synthesized on the lagging strand during replication.
