DNA Replication-PRACTICE 2

Front

What is the base pairing rule in DNA?

Back

In DNA, Adenine (A) pairs with Thymine (T) and Guanine (G) pairs with Cytosine (C).

Front

Where is DNA primarily located in a eukaryotic cell?

Back

DNA is primarily located in the nucleus of eukaryotic cells.

Front

What are the three components of a nucleotide?

Back

A nucleotide consists of a phosphate group, a 5-carbon sugar (deoxyribose in DNA), and a nitrogenous base.

Front

What is the process of DNA replication?

Back

DNA replication is the process by which a DNA molecule makes a copy of itself, resulting in two identical DNA molecules.

Front

What does semiconservative replication mean?

Back

Semiconservative replication means that each new DNA molecule consists of one original (parent) strand and one newly synthesized strand.

Front

What type of bond connects the nitrogenous bases in DNA?

Back

Hydrogen bonds connect the nitrogenous bases in DNA.

Front

What type of bond connects the sugar and phosphate in the DNA backbone?

Back

Strong covalent bonds connect the sugar and phosphate in the DNA backbone.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is the enzyme responsible for adding nucleotides to the growing DNA strand during replication.

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 important for replication and transcription.

Front

What is a replication fork?

Back

A replication fork is the area where the DNA double helix is unwound and separated into two single strands during replication.
