You have been studying a family of enzymes. you know that the original protein contains the amino acid sequence gly, trp, asp, ser, lys, arg. you start with several different samples, and you discover that each one has a different mutation in the amino acid sequence. you decide to assay each of them in the hope that at least one will have at least some activity. which of the following five sequences would you expect to give you the best result? a. gly, tyr, asp, ser, lys, arg b. asp, trp, asp, ser, lys, arg c. gly, trp, asp, ser, asp, arg d. gly, trp, asp, thr, lys, arg e. gly, met, asp, thr, lys, arg

The correct sequence from the five of the following is option D, which is Gly, Trp, Asp, Thr, Lys, Arg.

Explanation:

It is rightly assumed that the genetic code was absolute from the starting; it was the circumstances for the origin of life and its variability.

Rule 1: Same position in the four quadrants for essential hyperbolic codons.

Rule 2: Same or contiguous position in two quadrants for synonymous or related.

Rule 3: Same quadrant for equivalent codons.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
