DNA and RNA Review

Front

What is DNA?

Back

DNA stands for deoxyribonucleic acid, which is the molecule that carries the genetic instructions for life.

Front

What is RNA?

Back

RNA stands for ribonucleic acid, which plays a crucial role in coding, decoding, regulation, and expression of genes.

Front

What are genes?

Back

Genes are specific sections of DNA that contain the instructions for making proteins.

Front

What is the function of mRNA?

Back

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

Front

What is the function of tRNA?

Back

tRNA (transfer RNA) helps in the translation process by bringing amino acids to the ribosome to form proteins.

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 where ribosomes create proteins based on the information carried by mRNA.

Front

What is replication?

Back

Replication is the process of making an identical copy of DNA before cell division.

Front

Who are Crick and Watson?

Back

James Watson and Francis Crick are scientists known for discovering the double helix structure of DNA.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.
