Front

What type of bond joins nitrogenous bases in DNA?

Back

Hydrogen bonds are the type of bond that join nitrogenous bases in DNA.

Front

Why is DNA considered important?

Back

DNA serves as the blueprint for traits of all living things.

Front

What is the function of restriction enzymes in DNA manipulation?

Back

Restriction enzymes are used by scientists to cut DNA into smaller strands.

Front

What are the four nitrogenous bases found in DNA?

Back

The four nitrogenous bases in DNA are adenine, thymine, cytosine, and guanine.

Front

What makes up the rungs of the DNA ladder?

Back

The rungs of the DNA ladder are made up of nitrogen bases.

Front

What is the structure of DNA?

Back

DNA has a double helix structure, consisting of two strands that wind around each other.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What role does the sugar-phosphate backbone play in DNA?

Back

The sugar-phosphate backbone provides structural support and stability to the DNA molecule.

Front

What is complementary base pairing?

Back

Complementary base pairing refers to the specific pairing of adenine with thymine and cytosine with guanine in DNA.

Front

How does DNA replication occur?

Back

DNA replication occurs through the unwinding of the double helix and the synthesis of new complementary strands.
