When two nucleons combine , mass defect is caused which leads to loss of mass associated with energy and therefore the mass of nucleus is less than the mass of nucleons.  

Hence, Option B is correct.

professor190 [17]

Answer:

b. 17%

Explanation:

Let's begin by stating that the human genome possesses around 3,000 millions of base pairs.

Therefore, if this retrotransposon is around 1,000 base pair and possesses 516,000 copies, it will produce 516,000,000 of base pairs overall.

Let's consider,

516 millions

--------------------- × 100

3000 millions

= 17.2% (approximately 17%)

it gives us a percentage of the human genome which is for this transposon.
