What is the structure of a DNA molecule?

Back

A DNA molecule is structured as a double helix.

Front

What determines the genetic code in DNA?

Back

The genetic code in DNA is determined by the order (sequence) of the nitrogen bases.

Front

What are the three components of a nucleotide?

Back

The three components of a nucleotide are sugar, phosphate, and nitrogen base.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides.

Front

What is a nitrogen base?

Back

A nitrogen base is a component of nucleotides in DNA and RNA, which includes adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What is the role of thymine in DNA?

Back

Thymine is one of the four nitrogen bases in DNA that pairs with adenine (A) to form the rungs of the DNA ladder.

Front

How do nitrogen bases pair in DNA?

Back

In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).

Front

What is the function of DNA?

Back

The function of DNA is to store and transmit genetic information that guides the development and functioning of living organisms.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.

Front

What is replication in the context of DNA?

Back

Replication is the process by which DNA makes a copy of itself before cell division.
