The proteome is an expression of an organism’s genome. However, in contrast with the genome, which is characterized by its stability, the proteome actively changes in response to various factors, including the organism’s developmental stage and both internal and external conditions.
Where do genes encode?
A large molecule composed of one or more chains of amino acids in a specific order. Proteins are necessary for the structure, function, and regulation of an organism’s cells, tissues, and organs. Each protein has a unique function determined by its shape.
How much of genome is coding?
Scientists have been able to identify approximately 21,000 protein-coding genes, in large part by using the long-ago established genetic code. But these protein-coding regions make up only approximately 1 percent of the human genome, and no similar code exists for the other functional parts of the genome.
The proteome describes all the proteins within a cell, whereas the metabolome describes all the metabolites. The two are connected by many aspects of cell biology, in particular; cell signaling, protein degradation and generation, and post-translational modification.
How does the proteome differ from the genome quizlet?
The proteome is stable in somatic cells and unstable in germ cells, whereas the genome is stable in both somatic cells and germ cells.
