U1 - Proteins Flashcards
1
Q
What is the proteome
A
The proteome is the entire set of proteins expressed by a genome
2
Q
Why is the proteome larger than the number of genes
A
It is larger than the number of genes because more than one protein can be produced from a single gene as a result of alternative RNA splicing.
3
Q
What happens to the genes that are not expressed in a particular cell type
A
Genes that do not code for proteins are called non coding RNA genes and include those that are transcribed to produce tRNA, rRNA, and RNA molecules that control the expression of other genes
4
Q
What are the factors that effect the expression of proteins
A
Cellular stress
Metabolic activity of the cell
The response to signalling molecules
Diseased versus healthy cells
