What is the definition of genome

The genome of an organism is its entire hereditary information encoded in DNA

2
New cards

Composition of the genome

A genome is made up of genes and other DNA sequences that do not code for proteins

3
New cards

Function of the genome

DNA sequences that code for protein are defined as genes

New cards

State what is meant by a gene

A section of DNA that codes for a protein

5
New cards

Most of the eukaryotic genome is non-coding. State two possible roles or

outcomes of non-coding DNA sequences

Regulate transpiration and can be transcribed but not translated such as rRNA and tRNA

New cards

Name two types of RNA produced from DNA that are not translated into protein

tRNA and rRNA
