A DNA fragment with the sticky end sequence TGGCA will bind with another DNA fragment with the sticky end sequence _____
klio [65]

Answer:

A DNA fragment with sticky end sequence TGGCA will bind with another DNA fragment with sticky end sequence ACCGT.

Explanation:

When a DNA strand is separated by the restriction endonuclease, it forms two separate single strands. These strands or cuts are known as sticky ends as they are detached from the complementary pairs.

These cuts of DNA are without complementary pairs and when they find suitable base pair, they get attached to it. These sticky ends are allowed to fix with the complementary base pairs during PCR/ polymerase chain reaction.

They are called sticky ends as they are ready to stick with the complementary base pairs of nucleotides.

Calculate the average metabolic rate of a 65-kg person who sleeps 8.0h, sits at a desk 6.0h, engages in light activity 6.0h, wat
Anna35 [415]

Calculate the average metabolic rate of a 65-kg person who sleeps 8.0h, sits at a desk 6.0h, engages in light activity 6.0h, watches TV 2.0h, plays tennis 1.5 h, and runs 0.50h daily, If the metabolic rate for sleeping is 70 J/s, for sitting is 115 J/s, for engage in light activity is 230 J/s, for watching TV is 115 J/s, for playing tennis is 460J/s and for running is 1150 J/s.

Answer:

171.8 W

Explanation:

The Average metabolic rate can be deduced by multiplying each entity performed at a some particular hour of time with their corresponding energy, all divided by 24 hours.

Average metabolic rate = \frac{(8.0*70)(6.0*115)(6.0*230)(2.0*115)(1.5*460)(0.5*1150)}{24}

                                        = 171.8 W
