Answer:
The best answer to the question: When the ribosome reaches a stop codon on the mRNA, no corresponding tRNA enters the A site. If the translaton reaction were to be experimentally stopped at this point, which of the following would you be able to isolate, would be, A: An assembled ribosome with a polypeptide attached to the tRNA in the P site.
Explanation:
When mRNA is ready to be translated, ribosomal units assemble around the chain to begin the translation. In order for this translation to be correct, and follow a specific, and desired, pattern, the ribosome counts with a series of sites that, when they meet the appropriate signals in the mRNA sequences, it will know when to stop assembling tRNA and with it polypeptides. As such, once a ribosome meets what is known as a stop codon, tRNA and its consequently binding parts of a protein will also stop.
The P site is the second binding site for tRNA in a ribosome. During translation the P site is the one responsible for holding together tRNA and its attaching and growing polypeptide chain. When the process is ended by reaching a stop codon, the bond between the peptydil at the P site and tRNA is broken and the new protein is thus released. Therefore, if in a hypothetical situation, you were to stop the translation process precisely at the point where tRNA has entered the A site, which is the beginning of the translation sequence, you would be able to find the assembled ribosome, and the growing polypeptide chain attached to the already started tRNA on the P site.
Strong base. Anything below seven is an acid while anything above it will be a base. Seven is Neutral because it is directly in the middle. <span />
Can be methan.
Due to the decomposing process, methan is released into the air and it can be collected in some special tanks
Through suppression of the aconitase enzyme in the tricarboxylic acid cycle, aconitase, fluoroacetate is extremely hazardous to humans and other mammals.
'Lethal synthesis' of an isomer of fluor citrate is the cause. fluoroacetate is present in many different plant species, and ruminant animals can die from ingesting them consists of aconitase.
With the chemical formula FCH 2 CO 2 Na, sodium fluoroacetate is an organofluoride. The taste of this colorless salt, which is utilized as a metabolic toxin, is comparable to that of sodium chloride. Potassium and sodium salts are both derived from fluor acetic acid. In 1942, a report on the efficiency of sodium fluoroacetate as a rodenticide was published.
