Understanding DNA and Proteins

Front

What is a gene?

Back

A section of a chromosome that carries the code for a protein.

Front

Which base pairs with Adenine (A) in DNA?

Back

Thymine (T).

Front

What is the shape of a DNA molecule?

Back

Double helix.

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the function of DNA?

Back

To store and transmit genetic information.

Front

What is the relationship between DNA and chromosomes?

Back

Chromosomes are strands of tightly wound DNA.

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

Why do scientists only write the sequence of nitrogenous bases when describing DNA?

Back

Because the sugar and phosphate molecules are the same in all living things.

Front

What is the process of DNA replication?

Back

The process by which DNA makes a copy of itself before cell division.

Front

What role do proteins play in the body?

Back

Proteins perform a variety of functions including catalyzing biochemical reactions, providing structure, and regulating processes.
