Genetic Code

Front

What is the genetic code?

Back

The genetic code is the set of rules by which information encoded in genetic material (DNA or RNA) is translated into proteins by living cells.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid or a stop signal during protein synthesis.

Front

What does the codon CCU code for?

Back

Proline.

Front

What is the process of transcription?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically messenger RNA (mRNA).

Front

What is the process of translation?

Back

Translation is the process by which ribosomes synthesize proteins using the mRNA sequence as a template.

Front

What are chromosomes?

Back

Chromosomes are long strands of DNA that contain genes, which are the units of heredity.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.

Front

What is the significance of the start codon AUG?

Back

AUG is the start codon that signals the beginning of protein synthesis and codes for the amino acid Methionine.

Front

How many amino acids are coded by the DNA sequence ATCAGTGAT?

Back

3 amino acids.

Front

What is the order of events in protein synthesis?

Back

Transcription -> Translation -> Protein.
