Why does chromatin remodeling have to be the first step in gene activation? why does chromatin remodeling have to be the first s
mezya [45]

Answer:

Option 1:  Eukaryotic DNA can be highly packaged in condensed chromatin and inaccessible to transcription factors and RNA polymerase.

Explanation:

A process in which chromatin is rearranged in such a way that it comes in a state ready to began the transcription is known as Chromatin remodeling.

Basically, what happens during chromatin remodeling is chromatin changes from a condensed state into a suitable state to begin transcription, in which DNA binding proteins and transcription factors have access to bind to the DNA and start the process of transcription or gene expression smoothly.

Significance of chromatin remodeling:

  • The process of chromatin remodeling holds immense importance in the expression of genes because if this remodeling will not occur, the most important gene expression controlling factors would not be able to access DNA and start transcription. Therefore, chromatin remodeling must has to be the first step in gene activation.
  • When chromatin is tightly packed,it is referred to as heterochromatin. But when chromatin becomes loose and accessible for transcription it is referred to as euchromatin (please see attached figure for a better understanding).
  • Once heterochromatin is changed into euchromatin, the process of transcription begins and makes it possible for the expression of genes in a timely and coordinated fashion.

Hope it helps!

How have scientists determined the earth's core is composed of iron and nickel?
Sedaia [141]
<span>The correct option from the given options is: "Scientist have determined the composition of Earth's core by using radiometric dating to examine meteorites".
</span><span>To date materials the procedure of radiometric dating or radioactive dating is used, for example, rocks or carbon, in which trace radioactive impurities were specifically fused when they were framed. The strategy looks at the abundance of a normally happening radioactive isotope inside the material to the abundance of its decay items, which shape at a known consistent rate of decay.</span>

Answer:

1.) Nucleic acid is an important class of macromolecules found in all cells and viruses.

2.) Two examples of nucleic acids include deoxyribonucleic acid (better known as DNA) and ribonucleic acid (better known as RNA). These molecules are composed of long strands of nucleotides held together by covalent bonds.

3.) Amino acids are the monomers that make up proteins.

4.) Phosphorus, Selenium, Iron, Zinc, Copper, Manganese, and Potassium.

5.)  Protein helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions.

6.)     Actin, tubulin, keratin.

You're welcome. Took a while, but worth it--

When the air pressure decreases, what happens to the wind speed?
bogdanovich [222]

Answer:

Thus, if the upper level divergence is removing molecules faster than the low level convergence the surface low pressure will decrease. This decreases the surface pressure which increases the pressure gradient force, which increases the wind speed and causes the air to rush in faster towards the low pressure center.
