Answer:

3/4

Explanation:

If we assume simple dominance and independent assortment for each trait, we can use Mendel's Law of Segregation to predict the phenotypic proportions in the offspring of the parental cross AABBCc x AabbCc.

<h3><u>Gene A</u></h3>

AA x Aa

  • F1 genotypes: 1/2 AA, 1/2 Aa
  • F1 phenotypes: all A
<h3 /><h3><u>Gene B</u></h3>

BB x bb

  • F1 genotypes: 1 Bb
  • F1 phenotypes: all B
<h3 /><h3><u>Gene C</u></h3>

Cc x Cc

  • F1 genotypes:  1/4 CC, 2/4 Cc, 1/4 cc
  • F1 phenotypes: 3/4 C, 1/4 cc

We want to know the proportion of progeny with all dominant phenotype (A_B_C_). Since the genes are independent, we can multiply the probabilities of each gene to obtain the overall probability of having a ABC progeny:

<h3>1 A_ x 1 B_ x 3/4 C_ = 3/4 A_B_C_</h3>

The function of the beta subunit is to prevent DNA polymerase III from dissociating from the template DNA strand while still all
leva [86]

Answer:

The alpha helices in the beta subunit are a ring shaped protein.

Explanation:

<em>Because the beta encircles DNA like a ring used gel filtration and radioactive beta subunit. Tipically beta and gamma complex are needed for fast and processive synthesis by polymerase III core. Some researchers  realized that adding polymerase III  core to the gel filtered isolated ³H-beta- DNA provide fast DNA synthesis typical of the polymerase III holoenzyme. Therefore the gamma complex is only needed to get the beta subunit onto the DNA, and is not required afterward.</em>

If Plant A with yellow flower (dominant trait) is crossed with Plant B white flower (recessive trait), what is the percentage of
marysya [2.9K]

Answer:

100%

Explanation:

Yellow flower color (Y) is dominant over white flower color (y). Plant A is YY while plant B is yy:

       YY    x    yy

  Yy    Yy    Yy    Yy

All the offspring would have Yy genotype and since Y is dominant over y, all of them will have yellow flower color as opposed to while.

<em>Hence, the percentage of the offspring that will have a yellow flower would be </em><em>100%.</em>
