Higher-order folding involves association of the DNA with a nuclear scaffold, which contains large amounts of Histone H1 and Topoisomerase II.

<h3>What is Histone?</h3>

Histones are highly basic proteins abundant in lysine and arginine residues that provides structural support for a chromosome. They are found in eukaryotic cell nuclei. They act as spools around which DNA winds, which gives the chromosome a more compact shape, to create structural units called nucleosomes. Nucleosomes in turn are wrapped as 30-nanometer fibers that form tightly packed chromatin. There are five types of histones namely H2A, H2B, H3, H4 and H1 linker histone. Within a nucleosome, they exist as two dimers of (H2A-H2B) and a complex of (H32-H42) eventually forming an octamer.

<h3>What is Topoisomerases?</h3>

Topoisomerases are nuclear enzymes which play essential roles in DNA replication, transcription, chromosome segregation, and recombination.

Alex787 [66]

Answer:

The correct answer is ;

1. evolution.

2. growth and development

3. every living organism grows or develop

Explanation:

Fossils and traces and body remain provide information about the evolution of organisms and earth was found and how much it is change from then to modern organism and modern earth.

Comparing the skeleton of an adult horse to that of newborn foal provides the information of growth and development of the bones of foal to the adult horse.

Developing or growing is the property of life which is found in every living organism and comparison of the DNA sequence of Equus and Merychippus and draws conclusions about their genes and proteins isan example of this property.

What is the increase in temperatures due to more greenhouse gases?

xeze [42]

Answer: Since the industrial revolution, human activities have also resulted in an increase in natural greenhouse gases, especially carbon dioxide. An increase in these gases in the atmosphere enhances the atmosphere's ability to trap heat, which leads to an increase in the average surface temperature of the Earth.
