DNA Replication

Front

What is the role of helicase in DNA replication?

Back

Helicase is the enzyme that unwinds and unzips the DNA double helix to prepare for replication.

Front

Why is DNA important for living organisms?

Back

DNA contains genes that code for proteins, which result in traits and functions essential for life.

Front

What type of bonds hold the two strands of the DNA double helix together?

Back

Hydrogen bonds hold the two strands of the DNA double helix together.

Front

Which enzyme is known as 'The Builder' in DNA replication?

Back

DNA Polymerase is responsible for adding nucleotides to the growing DNA strand.

Front

How do the two strands of DNA run in relation to each other?

Back

The two strands of DNA are antiparallel, meaning they run in opposite directions.

Front

What is the function of DNA polymerase?

Back

DNA polymerase adds nucleotides to the growing DNA strand during replication.

Front

What is the significance of the antiparallel structure of DNA?

Back

The antiparallel structure allows for proper base pairing and replication of the DNA strands.

Front

What is the function of primase in DNA replication?

Back

Primase synthesizes a short RNA primer to provide a starting point for DNA polymerase.

Front

What is the role of ligase in DNA replication?

Back

Ligase joins Okazaki fragments on the lagging strand, sealing nicks in the sugar-phosphate backbone.

Front

What are Okazaki fragments?

Back

Okazaki fragments are short sequences of DNA synthesized on the lagging strand during DNA replication.
