DNA Structure and Function

Front

What are the four nitrogenous bases found in DNA?

Back

Guanine, Adenine, Cytosine, Thymine.

Front

What direction do new nucleotides get added during DNA replication?

Back

From the 5' side towards the 3' side.

Front

What is the base pairing rule in DNA?

Back

Adenine pairs with Thymine (A-T) and Cytosine pairs with Guanine (C-G).

Front

What is DNA fingerprinting?

Back

A method used to identify individuals by analyzing their DNA fragments sorted by size.

Front

What is the genetic code?

Back

The arrangement of nitrogenous bases (A, T, C, G) that provides instructions for building all parts of living organisms.

Front

What is a nucleotide?

Back

The basic building block of DNA, consisting of a nitrogenous base, a sugar, and a phosphate group.

Front

What is the role of DNA polymerase?

Back

An enzyme that synthesizes new DNA strands by adding nucleotides in the 5' to 3' direction.

Front

What is gel electrophoresis used for?

Back

To separate DNA fragments based on their size.

Front

What is the structure of DNA?

Back

A double helix formed by two strands of nucleotides twisted around each other.

Front

What is the function of helicase in DNA replication?

Back

An enzyme that unwinds the DNA double helix.
