Answer:
the deliberate modification of the characteristics of an organism by manipulating its genetic material.
Explanation:
<span>The answer which is a correct statement about the events of the cell cycle is 4) Interphase consists of the G1, S phase, and G2 phase - it also consists of G0 phase, but that is not included in this option. 1 is incorrect because many important processes occur during these phases, 2 is incorrect because this happens during metaphase, and 3 is incorrect because M is not the longest phase. This means that the correct answer is 4.</span>
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.
Answer: the major function of mucus is to protect the lung through mucociliary clearance against foreign and chemicals entering the lung.

Answer:
C. Objects with a small inertia are harder to accelerate than objects with a large inertia.
