DNA Structure and Replication Flashcard

Front

What is the first step in DNA replication?

Back

DNA Helicase unwinds the original DNA strand.

Front

What is the goal of DNA replication?

Back

To make a new copy of DNA from an existing strand of DNA.

Front

What does it mean that DNA is anti-parallel?

Back

The two strands of DNA run side by side but in opposite directions.

Front

What is the five-carbon sugar found in DNA?

Back

Deoxyribose.

Front

Which DNA base pairs with adenine (A)?

Back

Thymine (T).

Front

What is the role of RNA Primase in DNA replication?

Back

RNA Primase lays down RNA primer for new nucleotide bases.

Front

What enzyme builds new DNA strands during replication?

Back

DNA Polymerase.

Front

What is the function of DNA Ligase?

Back

Ligase knits together fragments on the lagging strand.

Front

What are the building blocks of DNA?

Back

Nucleotides.

Front

What are the components of a nucleotide?

Back

A phosphate group, a five-carbon sugar, and a nitrogenous base.
