inessss [21]

Answer:

Here is the complete question

The initiation of transcription requires melting of the DNA double helix, i.e. separating hydrogen-bonded base pairs, immediately upstream of the +1 site. In E. coli this melting is accomplished by ___________.

-DNA helicase unwinding the double helix around the +1 site.

-DnaA:ATP complexes binding to and twisting the double helix at the +1 site.

-RNA polymerase obtaining the energy to cause separation of strands from ATP hydrolysis.

-binding of the DNA complexes to the double helix at the +1 site and twisting of the double helix.

-bases at the promoter region flipping outward from the double helix into pockets on the polymerase.

And the answer is.....

bases at the promoter region flipping outward from the double helix into pockets on the polymerase.

The ability of the human body to break down the red color in beets is controlled by an autosomal dominant allele. The inability

Zinaida [17]

Answer:

Explanation:

Let the ability to break down the red color in beets be represented by the allele B. The inability would be represented by the allele b.

A nonsecretor's genotype would be BB or Bb while a secretor's genotype would be bb.

A nonsecretor woman with a secretor father would be a carrier with genotype Bb. A nonsecretor man who in a previous marriage had a secretor daughter would also be a carrier with genotype Bb. If the two marries:

Bb x Bb

BB 2Bb bb

(a) probability of their first child will be a secretor girl = probability of having a girl and being a secretor.

Probability of having a girl = 1/2

Probability of being a secretor = 1/4

probability of their first child will be a secretor girl = 1/2 x 1/4 = 1/8

(b) Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor.

Probability of having a girl = 1/2

Probability of being a nonsecretor = 3/4

Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor = 1/2 x 3/4 = 3/8

2. Probability that their first two children will be nonsecretors of either sex = probability of their first being a nonsecretor and of either sex and probability of their second being a nonsecretor and of either sex.

= 3/4 x 3/4 = 9/16
