DNA & protein synthesis

Front

What is a codon?

Back

A codon is a three-nucleotide sequence in mRNA that codes for a specific amino acid.

Front

What role does tRNA play in protein synthesis?

Back

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

Front

What is the process of DNA replication?

Back

DNA replication is the process of copying the DNA molecule to produce two identical copies.

Front

When does DNA replication occur?

Back

DNA replication occurs before mitosis begins.

Front

How many amino acids are coded by the sequence ATG GGA ACT CCA?

Back

The sequence ATG GGA ACT CCA codes for 4 amino acids.

Front

What is the function of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is transcription?

Back

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

Front

What is translation in protein synthesis?

Back

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

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where proteins are synthesized by translating mRNA.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids.
