Are the organelles that process coded genetic messages and assemble amino acids into proteins

Answer

            Ribosome is an imporatnat cell organelle that play a key role in protein synthesis.

Discovery

            Ribosome was discovered by Palade in 1955.

Structural composition

             Chemically it is composed of an equal amount of rRNA and proteins, thats why it is also known as ribonucleoprotein.

Sub units of ribosomes

             Ribosome is composed of two sub units one is smaller and the other one is larger. Both units are attached with each other with help of Mg atom.

Size of ribosome

             In prokaryote the ribosome size is 70S, while in eukaryotes its size is 80S.

Polysome

          When many ribosomes are attached to one mRNA strip it is called polysome or poly ribosome.

Role of ribosome

             Ribosomes are the sites of synthesis of protein from amino acids.

Mechanism

       mRNA which is the exact copy of DNA and formed in transcription come out from nucleus and attached to ribosomes. Now tRNA catch amino acids and come toward ribosome where its anti code match with genetic code of mRNA and then bonded to it. In this fashion a lot of amino acids are accumulated which make bonds with each others. Thus message present on mRNA in the form of genetic codes convert into protein through the process of transliteration.

easy

explanation:

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
