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 pulmonary circuit is supplied by both the right and the left sides of the heart. True False
egoroff_w [7]

Answer:

Answer is false.

Explanation:

The pulmonary circuit can be described as the route through which deoxygenated blood moves away from the right ventricle of the heart to the lung, so that the blood can mix with oxygen, and become oxygenated blood.

This simply means that, the right side of the heart allows or moves the blood via pulmonary circuit , in order to be enriched with oxygen.

In this sense, it can be concluded that, the pulmonary circuit is supplied only by the right side of the heart.

Note that, the oxygenated blood from the lung follow systemic circuit. This means that the oxygenated blood move back to the left atrium and supply to parts of the body.
