From DNA to protein - 3D with Английский subtitles   Complain, DMCA

here is a cell the basic unit of all

in most human cells there is a structure

in humans the genome is split between 23

each chromosome contains a long strand

tightly packaged around proteins called

within the dna are sections called genes

these genes contain the instructio­ns for

when a gene is switched on an enzyme

called rna polymerase attaches to the

it moves along the dna making a strand

of messenger rna out of three bases in

the dna code determines the order in

which the free bases are added to the

this process is called transcript­ion

before the messenger rna can be used as

a template for the production of

proteins it needs to be processed

this involves removing and adding

the messenger rna then moves out of the

protein factories in the cytoplasm

called ribosomes bind to the messenger

the ribosome reads the code in the

messenger rna to produce a chain made up

there are 20 different types of amino

transfer rna molecules carry the amino

the messenger rna is read three bases at

as each triplet is read a transfer rna

delivers the correspond­ing amino acid

this is added to a growing chain of

once the last amino acid has been added

the chain folds into a complex 3d shape
