Answer:

<h2>A</h2>

Explanation:

1. As given, the of a strand DNA contain sequence;

A-T-G-C-C-A-T-C-G-G-T-A,

2. After exposure to UV light, the strand contain the bases;

A-T-G-G*-C-C-A-T-C-G-G-T-A,

3. By comparing both the strands, we find that, the strand of DNA after exposure to UV contain extra G nucleotide between G and C, which is resulted by an insertion.

So we can say that, a new base has been inserted.

Suppose concordance data were collected from a cohort study of twins to study the genetic contribution to the onset of type 1 di
Dmitry_Shevchenko [17]

Answer:

The heritability of type 1 diabetes is likely high, indicating that genetics plays a larger role in the development of type 1 diabetes than the environment.

Explanation:

Identical twins are formed when a single zygote separates into two embryos after the process of fertilization. Hence, these twins arise from the same egg and sperm.

Fraternal twins arise when two different sperms fertilize two eggs at the same time.

Hence, we can say that the genotype of the identical twins is similar.

The results from concordance data prove that genetics play a higher role in type 1 diabetes.

Which class of molecules can directly cross the cell membrane without the aid of transport proteins? Choose one: A. Ions B. Suga
yulyashka [42]
Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.

Jobisdone [24]

A mushroom-shaped landform consisting of a column of less resistant rock supporting a broader extent of wind-resistant rock is termed a yardang. Yardangs form in environments where prevailing winds are strong and move in a single direction. Yardangs occur in various deserts of the world such as the Turkistan and the Mojave deserts.

Under the right circumstances, the lysogenic cycle changes to the lytic cycle. Explain whether the lytic cycle can change to the
kap26 [50]

Answer:

The correct answer is - no it cant not change from the lytic cycle to the lysogenic cycle.

Explanation:

In the lysogenic cycle, phage DNA is fused into the host genome, where it is moved to the next generation with the host genome. Natural stressors, for example, exposure to toxic compounds or starvation may cause the prophage to extract and enter the lytic cycle where the virus burst or kill the host genome.

So, in the lytic cycle virus kills the host cell s there is no chance or need to change into the lysogenic cycle as whereas in the lysogenic cycle virus incorporated with the host and becomes a chromosome.
