The answers;
1. Termination. Out of the 64 codons, UAG, UAA, and UGA are the stop codons that terminate translation when encountered by the ribosome. These three do not code for any amino acid but rather cause the translation complex to dislocate.
2. Translation. In this process, the ribosome ‘reads’ the codon and brings in a t-RNA with an anticodon to the codon. This tRNA carries a specific amino acid (for that codon) and engages in the P-site of the ribosome. The amino acid is taken from the t-RNA and used to elongate the polypeptide chain being formed. Thereafter the empty t-RNA dislocates.
3. Aminoacyl-tRNA synthetase. When a tRNA brings in an amino acid to the initiation complex, it is dislocated when ‘empty’. Aminoacyl-tRNA synthetase then catalyzes the reattachment of another amino acid through a chemical reaction called esterification. The cognate tRNA then become an aminoacyl-tRNA.
4. tRNA . Every tRNA has an amino acid attached to it. The type of amino acid (out of the 22 amino acids) is determined by the anticodon on the tRNA. There are many codons that are amino acids meaning that there are redundant codons that specify for the same amino acid.
5. Initiation. Initiation begins by the formation of an initiation complex. This complex is comprosed by the two subunits of the ribosome, and the mRNA. The complex becomes compelete when a Met-tRNA (a tRNA with a methionine amino acid) engages the P-site and then translation begins.
Explanation:
With few exceptions, cellular membranes — including plasma membranes and internal membranes — are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains. Glycerol is a three-carbon molecule that functions as the backbone of these membrane lipids.
Answer:
The wastes or run off of the industrial farming enters the water and nearby cultivated crops, this waste consist of chemicals and pesticides mostly, that are the cause of destruction of not only the cultivated crops but also the useful soil-borne rhizoshpere bacteria too. On the other hand climate change impacting from emission of greenhouse gases, increase air pollution and also cause deforestation. Such circumstances could all lead to the extinction of important crops.
In order to avoid these problems, proper waste management systems should be developed to dispose the waste of industries and others at area that is far from the population or cultivation. The climate change resulting from the pollution could be avoided by the use of filtered products for the smokes, so that filter could absorb harmful substances and the smoke released in air would not be that much toxic. Moreover, there is the need to identify and grow such crops that can adapt these environmental changes.
I would say B, <span>differ greatly between single solar systems. As we all know, I believe this is the only planet with life, but there might be many out there, too. Each planet should have very different characteristics unlike ours. So it may vary.</span>
Under saturated or perhaps they are looking for hypotonic (remember 'hypo' rhymes with 'low' - for 'low' solute concentration).
