Front

What is the role of DNA in protein synthesis?

Back

DNA provides the instructions needed to sequence amino acids during protein synthesis.

Front

What is mRNA and its function?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the function of tRNA in protein synthesis?

Back

tRNA (transfer RNA) brings the appropriate amino acids to the ribosome during protein synthesis.

Front

What is a gene?

Back

A gene is a segment of DNA that contains the instructions for making a specific protein.

Front

What is the Central Dogma of molecular biology?

Back

The Central Dogma describes the flow of genetic information from DNA to RNA to protein.

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, linked together in a specific sequence.

Front

What is a promoter in DNA?

Back

A promoter is a specific region of DNA where RNA polymerase binds to initiate transcription.

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 of synthesizing proteins from mRNA at the ribosome.

Front

What are exons and introns?

Back

Exons are coding regions of a gene that are expressed, while introns are non-coding regions that are removed during RNA processing.
