Слайды и текст этой презентации
Слайд 2Genes are functional fragments of DNA which are responsible for
the structure of a protein or a RNA molecule.
How does
the hereditary information turns into body traits?The process of genetic information conversion to individual properties is called the protein synthesis, which one includes several stages and involves both RNA and DNA.
Synthetic reactions occur partially in the nucleus but principally in cytoplasm.
Слайд 3Proteins roles in the human body
Why proteins do matter?
It
because of their participation in a lot of processes and
structures in our body.
Слайд 5RNA types roles in protein synthesis
Protein Synthesis (Updated)

Слайд 6TRANSCRIPTION: (nucleus)
- DNA unzips, using the enzyme, helicase, which
unwinds it and breaks the hydrogen bonds.
- CBP (complementary
base pairing) occurs when RNA nucleotides move into place with A→U, T → A, G → C, and C → G. - The RNA nucleotides rejoins, using the enzyme, RNA polymerase.
Слайд 7Genes contain sections of DNA called introns, which are interruptions
and are removed by ribozymes, and exons (expression), which get
expressed or become the protein..
Слайд 8TRANSLATION: (ribosome)
- Once the mRNA has let the nucleus,
it gets associated with ribosomes;
- mRNA binds to smaller ribosomal
subunit, then the larger subunit joins. 
Слайд 9polypeptide lengthens 1 amino acid at a time;
the ribosome
is large enough for 2 + RNA molecules, 1 coming,
1 outgoing.- a stop codon does not have a special tRNA molecule so this allows the mRNA to "fall off" the ribosome and the ribosome to break into 2 subunits.
Слайд 10- Several ribosomes, called a polysome, move along a strand
of mRNA at once, so several polypeptides of the same
type can be made at once using one mRNA molecule.
Слайд 11PROTEIN structuring: (ribosome)
1. peptide bonds
2. α-helix or β
sheet by H-bond
3. 3D structure covalent bonds between R-groups
4. several polypeptides
Слайд 12That is all about genes and traits, thank you
