The oxygen of air diffuses out from

Sladkaya [172]

Answer:

From higher concentration to lower.

Explanation:

The oxygen diffuses out from a region of higher concentration to the region of lower concentration because of diffusion. The air contain high amount of oxygen and human body has low oxygen level so the oxygen moves from the air to the lungs of the human body from there oxygen is loaded in the hemoglobin while on the other hand, carbondioxide is removed from the blood into the lungs which goes outside the body through breathing.

translation can be considered to have three phases or steps: initiation, protein synthesis, and termination. Please give a detai

iVinArrow [24]

Answer and Explanation:

Prokaryotic Translation :

Initiation :

First amino acid participating is f-methionine.
Requires three initiation components are $IF_1$ , $IF_2$ and $IF_3$
Initiation complex framed at Shine-Dalgarno succession of mRNA.
There is no concept of Kojak rule in prokaryotic.

Protein synthesis :

Faster process. Adds 20 amino acids per sec.

mRNA is poly-cistronic.

Occurs on 70S ribosome.

Termination :After translation, the formyl group of first formylated methionine is removed. Methionine is retained in the polypeptide chain

Eukaryotic Translation :

Initiation :

First amino acid taking part in translation if methionine.
Requires a set of eleven initiation factors, named as eIFn.
Initiation complex formed at 5’ end of mRNA.
Kojak rule followed

Protein synthesis :

Slow process. Adds 1 amino acid per second.
mRNA is mono-cistronic.
Occurs on 80S ribosome.

Termination :

Initiating methionine codon is removed from the polypeptide chain.
