Front

What are the three parts of a nucleotide?

Back

A nucleotide consists of a sugar, a phosphate group, and a nitrogenous base.

Front

Which part of a nucleotide is NOT present?

Back

Ribosome is NOT one of the three parts of a nucleotide.

Front

How many total nucleotides are in a DNA molecule with 10 base pairs?

Back

There are 10 nucleotides in the DNA molecule.

Front

What makes up the sides of a DNA ladder?

Back

The sides of a DNA ladder are made up of sugars and phosphates.

Front

What makes up the rungs (steps) of a DNA ladder?

Back

The rungs of a DNA ladder are made up of nitrogen bases.

Front

Which nitrogen base pairs with Cytosine?

Back

Cytosine always pairs with Guanine.

Front

What are the four nitrogen bases found in DNA?

Back

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

Front

What is the shape of the DNA molecule?

Back

The DNA molecule has a double helix shape.

Front

What is the function of DNA?

Back

DNA stores genetic information and provides instructions for the development and functioning of living organisms.

Front

What is the role of the phosphate group in a nucleotide?

Back

The phosphate group links the sugar of one nucleotide to the sugar of another, forming the backbone of the DNA strand.
