Review the numbered items below. Then, decide which of the following lists the correct steps of translation in the correct chron
ological order. I. UGA codon is identified.
II. DNA is unwound to expose a single template strand.
III. tRNA molecules carrying various amino acids bond to mRNA based on the sequence of mRNA codons.
IV. mRNA arrives at the ribosome
V. Introns are snipped out of an mRNA molecule.
V. tRNA, carrying methionine amino acid, bind to mRNA.
Translation is the process of synthesis of protein from with the help of messenger RNA (mRNA).
The process of translation include initiation, elongation and termination.
Initiation: In this step mRNA binds to ribososomes and tRNA, carrying start codon or methionine binds to mRNA.
Elongation:In this step, the tRNA molecules carrying several amino acid bind to mRNA based on the sequence of mRNA codon and then moves (translocates) to the next mRNA codon which leads to amino acid chain.
Termination: At the end, when a stop codon (UGA) identified, polypeptide is released.
So, the correct chronological order is IV, VI, III, I.
While linebreeding is less likely to cause problems in the first generation than does inbreeding, over time, linebreeding can reduce the genetic diversity of a population and cause problems related to a too-small gene pool that may include an increased prevalence of genetic disorders and inbreeding depression
When a person starts exercising (running) the increase in energy expenditure causes an elevation of oxygen consumption and carbon dioxide production. To compensate for this the respiratory control center senses the LOW oxygen level in blood and the HIGH carbon dioxide level and signals the diaphragm to contract and relax more often (INCREASE THE RATE).
It is more probable that the third one has a more developed sense of the vision with a large eye, and its movements. Also with a opened back to receive its nutrition and optic nerve.
