DNA Structure

Front

What is the structure of DNA?

Back

DNA is a double helix made up of two strands that are twisted around each other.

Front

What does it mean for DNA strands to be antiparallel?

Back

Antiparallel means that the two strands of DNA run in opposite directions.

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 nitrogen bases in DNA?

Back

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

Front

How do nitrogen bases pair in DNA?

Back

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

Front

Where is DNA located in eukaryotic cells?

Back

In eukaryotic cells, DNA is primarily located in the nucleus.

Front

What role do enzymes play in DNA replication?

Back

Enzymes help to unzip the DNA strands and synthesize new strands during DNA replication.

Front

What is the function of DNA?

Back

DNA carries genetic information that is used for the growth, development, and functioning of living organisms.

Front

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

Back

The double helix structure allows for the stable storage of genetic information and facilitates replication.

Front

What is the process of transcription in relation to DNA?

Back

Transcription is the process by which the information in a DNA strand is copied into messenger RNA (mRNA).
