Summarize the methods by which DNA was found to be located in chromosomes.

Biology
1 answer:
Pavlova-9 [17]3 years ago

Answer:

DNA packaging is the method to convert long DNA into condensed chromosomes. Histone protein is responsible for basic level packaging of DNA into the nucleosome. Histone proteins are positive in nature that neutralize the DNA's negative charge.

A nucleosome consists of eight histone proteins which wraps around 147 bp of DNA. Each nucleosome has linker histone which forms chromatosome.

The next level of organization is the compaction of nucleosome into approx 30nm diameter fiber due to the attraction between nucleosomes.  

Then protein condensin helps in making the 30 nm chromatin fiber to condense more to become a chromosome which is 1000 fold smaller than its original length.

Which factor can decrease the rate of a chemical reaction?
Illusion [34]

(c)Low Temperature of the Reactants can decrease the rate of a chemical reaction.

How temperature effects the rate of a chemical reaction

Chemical reactions typically occur faster at higher temperatures. Food can spoil quickly when left on the kitchen counter. However, the lower temperature inside of a refrigerator slows that process so that the same food remains fresh for days. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.Thus decrease in the temperature of a reaction can help in decreasing the rate of a chemical reaction.Lower the temperature lower the chemical reaction rate.
