Front

How do the base pairing rules contribute to the structure of DNA?

Back

They enable the double helix structure by pairing specific bases.

Front

Explain why DNA is important for living organisms.

Front

What is a nucleotide?

Back

The basic building block of DNA, consisting of a phosphate group, a sugar, and a nitrogenous base.

Front

What is the role of the sugar in a nucleotide?

Back

It connects the phosphate group and the nitrogenous base, forming the backbone of DNA.

Front

What are complementary base pairs in DNA?

Back

Adenine pairs with Thymine, and Cytosine pairs with Guanine.

Front

What is the function of DNA replication?

Back

To create an identical copy of DNA for cell division.

Front

What is the significance of the double helix structure of DNA?

Back

It allows for the compact storage of genetic information and protects the DNA strands.
