what component of the cell is the site of polypeptide assembly?
dna polymerase
transcription is the process where genetic information in dna is used to produce a complementary rna strand. this rna strand is then processed to give messenger rna (mrna), which is free to migrate through the cell. mrna molecules bind to protein-rna complexes called ribosomes located in the cytosol, where they are translated into polypeptide sequences. the ribosome mediates the formation of a polypeptide sequence based on the mrna sequence. the mrna sequence directly relates to the polypeptide sequence by binding to transfer rna (trna) adapter molecules in binding pockets within the ribosome. the new polypeptide then folds into a functional three-dimensional protein molecule.
cell (biology)
cytochrome c oxidase (cox), the terminal component of the mitochondrial respiratory chain, catalyzes the electron transfer from reduced cytochrome c to oxygen. this component is a heteromeric complex consisting of 3 catalytic subunits encoded by mitochondrial genes and multiple structural subunits encoded by nuclear genes. the mitochondrially encoded subunits function in electron transfer, and the nuclear-encoded subunits may function in the regulation and assembly of the complex. this nuclear gene encodes polypeptide 2 (liver isoform) of subunit viia and the polypeptide 2 is present in both muscle and nonmuscle tissues. in addition to polypeptide 2, subunit viia includes polypeptide 1 (muscle isoform), which is present only in muscle tissues, and a related protein, present in all tissues. this gene may have several pseudogenes.
