The recognition sites for the restriction enzymes BamHI, XbaI and BglII are G^GATCC, T^CTAGA and A^GATCT, respectively. Which en
Goshia [24]

Answer:

(C) Only BamHI and BglII fragments are compatible.

Explanation:

First we can visualize how the enzymes cut by completing the strand below and cutting where indicated. The three enzymes cut with cohesive ends.

Then we can complete the sense of the strands and serach compatible ends. Keep in mind that we can only join 5 'ends with 3' ends.

BamHI =  G...3'               5'...GATCC  

               CCTAG...5'               3'...G

               

XbaI =      T...3'               5'...CTAGA

                AGATC...5'               3'...T

BglII =       A...3'              5'...GATCT

                TCTAG...5'              3'...A

In bold, leave the bases that remain in single strand and must be compatible with those of the other end.

To be compatible they must be complementary bases. A with T and C with G.  

Now you can see that only BamHI fragments are compatible with those of BglII.

Which of the following hominin taxa had the LARGEST average cranial capacity?
DiKsa [7]

Answer:

The correct answer is option c.

Explanation:

Starting from the initial primates to the hominids, and eventually, to Homo sapiens, the brain of humans has grown spontaneously. The volume of the brain has increased with the evolution of humans, that is, starting from about 600 cubic centimeters in Homo habilis to 1600 cubic centimeters in Homo neanderthalensis. The Homo neanderthalensis was the hominid with the largest size of the brain, that is, with the maximum cranial capacity. The enhancement in the size of the brain ceased with neanderthals. After that the shrinking of the brain size took place.
