The Genome Flashcards
A genome is the
complete set of genes present in a cell
The full genome is present within every cell of an organism, but not every gene is
expressed in every cell. Which genes are expressed depends on the cell type
The proteome is the full range of
proteins that a cell is able to produce
The proteome is usually larger than the genome of an organism why
This due to the large amount of post-translational modification of proteins (often in the Golgi apparatus)
Each gene is also capable of producing multiple different proteins via
alternative splicing(Many genes contain multiple exons as well as multiple introns. A process known as alternative splicing allows for different combinations of exons to be included in the final mature mRNA, making different versions of proteins (called isoforms) that are all encoded by the same gene
