Which of the following describes the primary structure of amino acids?

A replication fork is a structure formed during DNA replication when specific enzymes (i.e., helicases) separate both DNA strands at the origin of replication. DNA is always synthesized in the 5' to 3' direction, thereby DNA can be synthesized continuously on the leading strand, because the growth of this strand proceeds in the same direction as the movement of the replication fork, while DNA synthesized in several short segments on the lagging strand which are called 'Okazaki fragments'. DNA polymerases are enzymes that can only add nucleotides to the 3' end of a DNA strand, thereby they require the synthesis of short stretches of RNA or 'RNA primers', which are necessary for DNA replication of the lagging strand.

Merle is a marking pattern in canine coats that appears as a marbling of color in a solid coat. The merle gene displays incomple

Over [174]

Answer:

A)

1. double merle with short coat: 1/4 (e).

2. double merle with long coat: 0 (a).

3. merle with short coat: 1/2 (g).

4. merle with long coat: 0 (a).

5. solid with short coat: 1/4 (e).

6. solid with long coat: 0 (a).

B)

1. double merle with short coat: 3/16 (d).

2. double merle with long coat: 1/16 (b)

3. merle with short coat: 3/8 (f).

4. merle with long coat: 1/8 (c).

5. solid with short coat: 3/16 (d).

6. solid with long coat:1/16 (b)

Explanation:

<u>Available data</u>:

CSCS individuals display a solid coat
CMCS individuals are merle and show patches of fur with a lighter, mottled effect
CMCM individuals are "double merle" and show patches of fur with much more pronounced lightening
short coats, L-, being dominant to long coats, ll.

The purple color in a purple pea plant is dominant to a white-color. what would be the expected outcome of a cross between a pur

pentagon [3]

Well, it depends on the purple pea plant. Purple pea plants can have either PP or Pp.

White pea plants always have recessive, so it would have pp only.

So, the expected outcome of the cross would be -
PP x pp or Pp x pp

PP x pp = all the offspring would be purple in colour
or
Pp x pp = half would be purple and the other half would be white
