How are histone modification enzymes (such as HATs) and chromatin remodeling complexes recruited to unmodified chromatin, and ho

w are they thought to aid in the activation of transcription from previously silent genes?
Biology

kiruha [24]3 years ago

Answer:

A histone modification mechanism proliferate through a process that includes post translational modification procedure. The methylation, acetylation as well as ubiquitylation are one of the main modifiers that help in activation of silent genes and ultimately these covalently bonded histone modifiers help in regulating chromatin. The PTM has a main role in altering histone structure by these modifier's recruitment....

Unattached microbes are moved from the lungs to the epiglottis by the _______ effect.
lisov135 [29]

Answer:

The unattached microbes are moved from lungs to epiglottis by the <u>mucociliary escalator effect.</u>

Explanation:

Mucociliary escalator, also known as mucociliary clearance, is one of the major defense mechanisms that protects the lungs. It describes the self-cleaning mechanism of the bronchi which are present in the lungs. The effectiveness of this mechanism depends on the properties of the produced mucus and on the quality and number of the cilia present in the lining of the airway.

Therefore, the unattached microbes are moved from lungs to epiglottis by the <u>mucociliary escalator effect.</u>

Elephant seals are abundant in their population size but they have low genetic diversity within their species due to overhunting
Anastasy [175]
<h2>Genetic diversity </h2>

Explanation:

If the environment changes, the species runs the risk of not having the genetic diversity to be adaptable to that change and could go extinct

  • Genetic diversity is the diversity  or genetic variability within species
  • The huge variety of different gene sets defines an individual or a whole population's ability to tolerate stress from any given environmental factor
  • While some individuals might be able to tolerate an increased load of pollutants in their environment, others carrying different genes might suffer from infertility or even die under the exact same environmental conditions;the former will continue to live in the environment the latter will either have to leave it or die
  • Any change in the environment - natural or human induced causes a selection of events that only the fittest survive
  • In case of elephant seals,overhunting reduces the sum of genes available,thus leaving behind a population that is less capable of tolerating any further natural or human disturbances in environment
  • The loss of genetic diversity within a species can result in the loss of useful and desirable traits

"Darwin's finches" reside on the galapagos islands. Each species has a different type of break, however, they can all be traced
Lilit [14]

Answer:

The correct answer would be adaptive radiation.

It is a natural phenomenon by which ancestor species diversify into new forms as a result of adaptation towards changing the environment, limited or different resources, new challenges or new ecological niches.

For example, Darwin's finches faced new niches, different environment, different types of food resources due to which they adapt to different species bearing beaks of different shapes and sizes.
