DNA/RNA Review

Front

What is the structure of a DNA molecule?

Back

A DNA molecule is structured as a double helix.

Front

Who are the scientists credited with the discovery of the double helix structure of DNA?

Back

James Watson and Francis Crick.

Front

What determines the genetic code in a DNA molecule?

Back

The order (sequence) of the nitrogen bases determines the genetic code.

Front

If a DNA strand contains 20% Thymine, what percentage of Guanine is present?

Back

30%.

Front

What is the complementary DNA sequence for the strand ATG TGA CAG?

Back

TAC ACT GTC.

Front

What are the four nitrogen bases found in DNA?

Back

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

Front

What base pairs with Adenine in DNA?

Back

Thymine (T) pairs with Adenine (A).

Front

What is the role of DNA in living organisms?

Back

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

Front

What is RNA and how does it differ from DNA?

Back

RNA (Ribonucleic Acid) is single-stranded, contains ribose sugar, and has Uracil (U) instead of Thymine (T).

Front

What is the process of DNA replication?

Back

DNA replication is the process by which a DNA molecule makes a copy of itself before cell division.
