  • Most of the bioremediation processes includes oxidation-reduction reaction.
  • The natural degradation process of pollutants is improved by bioremediation.

Given the parents AABBCc × AabbCc, assume simple dominance for each trait and independent assortment. What proportion of the pro
galina1969 [7]
The answer is C) 3/4

Let's analyze separately each of the traits:

Parental generation: AA x Aa
F1 generation:       AA AA Aa Aa
So, all progeny will <span>phenotypically resemble the first parent.

</span>Parental generation: BB x bb
F1 generation:       Bb Bb Bb Bb
So, all progeny will <span>phenotypically resemble the first parent.
</span>
Parental generation: Cc x Cc
<span>F1 generation:       CC Cc Cc cc
</span>Only 3 (CC, Cc, Cc) out of 4 progeny will <span>phenotypically resemble the first parent.

The genotypes for first two traits will not affect </span>phenotypical resemblance to the first parent. So, it only counts the third trait, for which the chance to have progeny that <span>phenotypically resemble the first parent is 3/4.</span>

Restriction endonucleases are especially useful if they generate sticky ends. What makes an end sticky?
Mazyrski [523]

The question is incomplete as it does not have the options which are:

A) single-stranded complementary tails

B) blunt ends

C) poly-A sequences

D) 5' cap

E) interference

Answer:

A) single stranded complementary tails

Explanation:

Restriction endonuclease is the enzyme which cuts the DNA sequence in the internal sequence.

The endonuclease enzyme can cut the DNA sequence in a way that it can form the cuts with the single-stranded overhangs called sticky ends and without overhangs called blunt ends.

The sticky ends are produced when the enzyme makes cut at the single strand and then makes the cut at between the same base at the nitrogenous base. This type of asymmetrical cut forms the single-stranded overhangs which can form the complementary base pairs easily.

Thus, Option-A is correct.
