DNA and Protein Synthesis

Front

What is the role of DNA in protein synthesis?

Back

DNA contains the instructions for the synthesis of proteins, controlling the production of proteins in the cell.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically mRNA, which occurs in the nucleus.

Front

What is translation?

Back

Translation is the process where ribosomes synthesize proteins using the information carried by mRNA.

Front

What is the function of tRNA?

Back

tRNA (transfer RNA) carries amino acids to the ribosome during protein synthesis and matches them to the coded mRNA message.

Front

Where does translation occur in the cell?

Back

Translation occurs in the ribosome, which can be found in the cytoplasm.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains the sugar deoxyribose, while RNA is single-stranded and contains the sugar ribose.

Front

What is the purpose of replication?

Back

Replication is the process of copying DNA before cell division, ensuring that each new cell receives an identical set of DNA.

Front

What is an anticodon?

Back

An anticodon is a sequence of three nucleotides on tRNA that pairs with a complementary codon on mRNA during translation.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides on mRNA that specifies a particular amino acid.

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.
