Type II topoisomerases display all of the following characteristics EXCEPT

Biology
1 answer:
Firlakuza [10]3 years ago
6 0

Answer:

The correct answer is option A. "They only introduce supercoiling and cannot relax a covalently closed circular DNA".

Explanation:

Type II topoisomerases are enzymes that regulate the winding an unwinding of DNA during DNA replication. Basically, these enzymes are the scissor that remove the knots and tangles formed during the replication process. Is false to affirm that type II topoisomerases only introduce supercoiling and cannot relax a covalently closed circular DNA. Bacterial type II DNA topoisomerases  work with the circular DNA of bacterium by changing the linking number of circular DNA by ±2.

kow [346]

Hhv-5 infectious in pregnant women can be particular concern because this virus can be teratogenic.

<h3>What is teratogenic?</h3>
  • Teratology is the study of aberrant physiological development across the whole life cycle of all species, including plants.
  • Dysmorphology is a branch of medical genetics that focuses on the classification of congenital deformities.
  • Teratogens are substances that, when exposed to a pregnant woman, may result in physical or functional abnormalities in the human embryo or fetus.
  • Such substances include, for example, alcohol and cocaine.
  • A teratogen is an agent that increases a baby's risk of developing a birth defect or can actually cause one.
  • They are items to which a mother might be exposed while expecting.
  • Teratogens can result in neural tube abnormalities like spina bifida during this time.
  • Throughout the entire pregnancy, certain organs are vulnerable to teratogens.
  • The baby's brain and spinal cord are included in this.
  • Alcohol can be harmful at any point during pregnancy since it has an adverse effect on the brain and spinal cord.

How the process of natural selection canexplainhow evolution occurs?
harkovskaia [24]
In natural selection, there are three main things you need to know. There must be a variance in the genepool of course, or else to selection or evolution will take place. There also must be a selective force and time. Now, lets say that there is a population of many colored moths. But lets say that the brown colored moth blends in with the environment. This means that predators (selective force in this case) will have a much harder time finding these brown moths instead of easily finding some of the other colored moths (variation). This means that the brown moths will survive at a much higher rate because the are harder to find, and over time, the gene pool will narrow down to just brown moths because the rest of the moths die out due to predators and competition. This also means that this moth species has evolved over time to just become the brown colored moths only. Hope you can understand this but feel free to ask for clarification.
