The C. elegans genome is about 100,000kb. If C elegans genomic DNA is digested with XbaI, which recognizes and cleaves the seque
nasty-shy [4]

Answer:

25000 fragments

Explanation:

A restriction enzyme can cut a random DNA sequence once per every 4^n where n = number of bases in the recognition site of enzyme.

There are 6 bases in Xbal's recognition site (TCTAGA) so it will cut once per every 4^6 = 4096 bases (4kb).

Total genomic size = 100000kb

So expected number of fragments = Total genomic size/Size of one fragment

= 100000/4

= 25000 fragments

The graph shows the change in number of two populations, lions and zebras. The solid line represents the population of zebras an
9966 [12]
<span>The graph portrays predation. The relationship shows that an increase in the population of zebra results in a subsequent increase in the lion population, and vice versa. This, therefore, means that the lion population is dependent on the zebra population due to an interaction (predation).  The lion population will always be lower than that of the zebra because of the inefficiencies of energy transfer up the trophic levels (exhibited by a typical energy pyramid).  </span>
