As DNA replication continues and the replication bubble expands, the parental double helix is unwound and separated into its two
Korolek [52]

Answer:

DNA replication is initiated by the help of these enzymes.

Explanation:

Helicase enzyme helps is unwinding the two complementary strand of DNA by hydrolysing the hydrogen bonds present between the nitrogenous bases of the two opposite strands.

Topoisomerase enzyme help in expansion of the Replication bubble by releasing the super coiling or tension occured while unwinding by helicase. It breaks the phosphate bonds in one of the two strands ahead of replication bubble or fork to release super coiling or overwinding.  

Single-strand binding proteins gets bind to the separated strands to stabilize the structure of Replication bubble or to keep the both strand separated from each other.

Alcoholic fermentation:___________
Irina-Kira [14]

Alcoholic fermentation includes: <u>All answers are correct</u>

a. is carried out by yeasts.

b. produces far less ATP than aerobic respiration.

d. produces ethanol.

e. produces carbon dioxide.

Fermentation- Fermentation is an anaerobic process in which energy can be released from glucose even though oxygen is not available. Fermentation occurs in yeast cells, and a form of fermentation takes place in bacteria and in the muscle cells of animals.

Aerobic respiration- It is the process of cellular respiration that takes place in the presence of oxygen gas to produce energy from food. This type of respiration is common in most of the plants and animals, birds, humans, and other mammals. In this process, water and carbon dioxide are produced as end products.

How can the random distribution of alleles result in a predictable ratio?
levacccp [35]
Phenotypically and genotypically there are only two different ratios. If you think of a Punett square... 

<span>You could say that a pea plant with the trait for the dominant color green (G) could also carry the recessive trait for yellow (g). So let's say you mate a dominant green, (Gg) with another dominant green, (Gg). You would get 1 (GG), 2 (Gg) and 2 (gg). </span>

<span>Phenotypically (as in physical traitwise), the ratio is 3:1 because you have 3 green colored peas and one yellow. </span>

<span>Genotypically (as in traitwise), the ratio is 1:2:1, because you have 1 (GG), 2 (Gg) and 1 (gg). </span>

<span>So although it's random, for any specific trait there are only 4 different outcomes.</span>
