Africa is leading worldwide in terms of abundance of strategic minerals like diamond, platinum, chromium and many more. Other essential minerals such as gold, silver, copper and colored gemstones are critical minerals are imported from Afghanistan.
Answer:
The correct answer is - 130 kDa, 82 kDa, 45 KDa.
Explanation:
In the question given is there are 4 subunits in protein omicron in which two subunits are - 65 kDa and the other two subunits are - 85 kDa and 45 kDa.
So the size band would be in absence of beta-mercaptoethanol which is very essential to break down disulfide bonds that held together these subunits:
Size band = 65 KDa + 65 KDa
= 130 KDa (one band) (
65+65=130),
82, 45 as without beta mercaptoethanol disulfide bond is not broken
.
Thus, the correct answer is - 130 kDa, 82 kDa, 45 KDa.
