Structure and Function of DNA Review

Front

What is DNA?

Back

DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions for life.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is the base pairing rule in DNA?

Back

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

Front

What is a chromosome?

Back

A chromosome is a structure made of coiled up or condensed DNA that contains many genes.
