Suppose a newborn baby was accidentally mixed up in the hospital. In an effort to determine the parents of the baby, the blood t

ypes of the baby and two sets of parents were determined. Baby 1 had type O Mrs. Brown had type B Mr. Brown had type AB Mrs. Smith had type B Mr. Smith had type B .
a. Draw Punnett squares for each couple (you may need to do more than I square/ couple)
b. to which parents does baby # I belong? Why? Hint you may want to refer to your Punnett squares.

Answer:a. Draw Punnett squares for each couple (you may need to do more than 1 square/ couple)

Baby 2 MUST belong to the Browns because Mr. Brown is the only parent with an A allele to

contribute… then the rest works out as follows:

b. To which parents does baby #1 belong? Why? Hint you may want to refer to your Punnett

squares.

Baby 1 must belong to the Smiths, because they are the only ones with the possibility of EACH

having a recessive allele to pass down to the baby, Mr. Brown has type AB blood and therefore

only has the dominant A and dominant B alleles – no recessive allele possible.

A plasmid 41 twists and 6 right handed writhes. What is the Lk for this plasmid?
OLEGan [10]

Answer: Lk for this plasmid = 47

Explanation:

The formula to compute Lk is given by :-

Topological Linking Number (Lk): Twist (Tw) + Writhe (Wr)

Given: A plasmid 41 twists and 6 right handed writhes.

i.e. Twist (Tw) = 41   , Writhe (Wr) = 6

Then, Topological Linking Number (Lk) for this plasmid :  = 41+6

= 47

Hence, the Lk for this plasmid = 47
