DNA Replication

Front

What is the directionality of DNA strands?

Back

DNA strands are said to be anti-parallel, meaning they run in opposite directions.

Front

In which direction does DNA replication occur?

Back

DNA replication runs from 5' to 3'.

Front

What is the complementary nucleotide for Adenine in DNA?

Back

Thymine is the complementary nucleotide for Adenine.

Front

What role does DNA polymerase play in DNA replication?

Back

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

Front

What does it mean for DNA replication to be semi-conservative?

Back

Semi-conservative means that during DNA replication, one old (parent) strand is reused to synthesize a new strand.

Front

What are the four nucleotide bases in DNA?

Back

The four nucleotide bases in DNA are Adenine, Thymine, Cytosine, and Guanine.

Front

What base pairs with Cytosine in DNA?

Back

Guanine pairs with Cytosine in DNA.

Front

What is the significance of the 5' and 3' ends of a DNA strand?

Back

The 5' and 3' ends indicate the directionality of the DNA strand, which is crucial for replication and transcription.

Front

What is the first step in DNA replication?

Back

The first step in DNA replication is the unwinding of the double helix by helicase.

Front

What enzyme is responsible for unwinding the DNA double helix?

Back

Helicase is the enzyme responsible for unwinding the DNA double helix.
