Transcription and Translation

Front

What is transcription?

Back

Transcription is the process of making an RNA copy of a DNA strand, which occurs in the nucleus of a cell.

Front

What is translation?

Back

Translation is the process where ribosomes read mRNA to synthesize proteins.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when bases are added or deleted from the DNA sequence, causing the mRNA to be read out of sync.

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

Where does transcription occur?

Back

Transcription occurs in the nucleus of a cell.

Front

What is the role of mRNA?

Back

mRNA carries the genetic information from DNA to the ribosomes for protein synthesis.

Front

What is the role of tRNA?

Back

tRNA transports amino acids to the ribosome and matches them to the coded mRNA message.

Front

What is a codon?

Back

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

Front

What is DNA replication?

Back

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

Front

What is the function of ribosomes?

Back

Ribosomes are the cellular structures where protein synthesis occurs.
