DNA Replication-PRACTICE 1

Front

What is the process of DNA replication called when it results in two identical molecules, each with one original strand and one new strand?

Back

Semi-conservative replication.

Front

What part of the nucleotide is represented by #1 in a diagram?

Back

Phosphate.

Front

Why is DNA replication referred to as semi-conservative?

Back

Because it uses one original (parent) DNA strand to create a new strand.

Front

What is the role of DNA Helicase in DNA replication?

Back

DNA Helicase unwinds the original DNA strand.

Front

What does RNA Primase do during DNA replication?

Back

RNA Primase lays down RNA primer for new nucleotide bases.

Front

What is the function of DNA polymerase in DNA replication?

Back

DNA polymerase builds new strands by bringing in new nucleotide bases.

Front

What is the role of Ligase in DNA replication?

Back

Ligase knits together fragments on the lagging strand.

Front

What does the term 'anti-parallel' refer to in the context of DNA structure?

Back

It refers to the orientation of the sugar molecules on each strand being in opposite directions.

Front

What are the building blocks of DNA called?

Back

Nucleotides.

Front

What are the three components of a nucleotide?

Back

Phosphate group, deoxyribose sugar, and nitrogen base.
