Tutorial
Terms to Know
Codons

Sections of 3 nucleotides that code for an amino acid.

Exons

Sections of RNA that code for proteins.

Genetic Code

Information stored in the nucleotide sequence of DNA that forms our genes.

Protein Synthesis

The formation of proteins by using information stored in DNA to form proteins.

RNA Polymerases

An enzyme used to form a single strand of RNA from a DNA strand.

Regulatory Proteins

Proteins that can stop or speed up transcription.

Start Codon

A codon used to signal the start of an amino acid sequence on a strand of mRNA.

Stop Codon

A codon used to signal the stop of an amino acid sequence on a strand of mRNA.

Transcription

The process of converting DNA into RNA.

mRNA

Messenger RNA that is used to convert RNA code into protein.

rRNA

Ribosomal RNA is used to produce the structure of ribosomes.

tRNA

Transfer RNA that is used to bind ribosomes to the start codon of a nucleotide chain in order for translation to occur.
