What is the structure of DNA?

Back

DNA is a double helix structure composed of two strands of nucleotides twisted around each other.

Front

What are the four bases of DNA?

Back

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

Front

What is the complementary base pairing in DNA?

Back

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

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil instead of thymine.

Front

What is the role of DNA in cells?

Back

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

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the function of RNA?

Back

RNA plays a crucial role in protein synthesis and can also have regulatory functions in the cell.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA.

Front

What is translation?

Back

Translation is the process by which ribosomes synthesize proteins using the information encoded in mRNA.

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.
