DNA Structure

Front

What are the two molecules that form the sides (backbone) of the DNA ladder?

Back

Deoxyribose sugar and phosphate.

Front

If a DNA molecule consists of 29% Guanine, what percentage of Cytosine will it contain?

Back

29%.

Front

In eukaryotes, where is DNA usually found?

Back

In the nucleus.

Front

What molecule is represented by the structure shown in a typical DNA diagram?

Back

A DNA molecule.

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA, consisting of a deoxyribose sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogen bases found in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is the base pairing rule in DNA?

Back

Adenine pairs with Thymine, and Cytosine pairs with 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 difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.
