A gene normally contains an N' terminal ER signal sequence and an internal stop transfer sequence. The ER signal sequence is recognized and used during the protein trafficking process, as normal. After translation is completed a signal peptidase enzyme cleaves the N' ER signal sequence but the internal sequence is not cleaved.

Genomics

Genes are responsible for transmitting the characters located on the chromosomes from one individual to another across the generations. Genetics is the study of different genes that are involved in different functions. Genetics is a branch of biology that studies genes, genetic diversity, and heredity in living organisms. The genetic system consists of genetic notations, which is a system of signs and symbols. Genotype refers to the organism's genetic composition, and phenotype refers to the observable property of the organism.
