What is the structure of a DNA molecule?

Back

A DNA molecule is structured as a double helix, which resembles a twisted ladder.

What are the four nitrogen bases found in DNA?

Back

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

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is transcription?

Back

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

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, synthesizing proteins from mRNA.

Front

What is an anticodon?

Back

An anticodon is a three-base sequence on tRNA that is complementary to a codon on mRNA.
