Front

What are the building blocks of DNA?

Back

Nucleotides are the building blocks of DNA.

Front

What are the components of a nucleotide?

Back

A nucleotide is made up of a sugar, a phosphate group, and a nitrogenous base.

Front

What type of bond connects nitrogenous bases in DNA?

Back

Hydrogen bonds connect nitrogenous bases in DNA.

Front

What forms the sides of the DNA ladder?

Back

The sides of the DNA ladder are made up of sugars and phosphates.

Front

What forms the rungs of the DNA ladder?

Back

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

Front

What is the shape of DNA?

Back

DNA has a double helix shape, resembling a twisted ladder.

Front

Name the four nitrogenous bases in DNA.

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

Which nitrogenous bases pair together in DNA?

Back

Adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Front

What is the role of DNA?

Back

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

Front

How does DNA replicate?

Back

DNA replicates by unwinding and separating the two strands, then using each strand as a template to form new complementary strands.
