Chromatin is the material that makes up a chromosome that consists of DNA and protein. The major proteins in chromatin are proteins called histones.
<h3>
<em><u>They act as packaging elements for the DNA.</u></em></h3>
The reason that chromatin is important is that it's a pretty good packing trick to get all the DNA inside a cell.
Quaternary structures of proteins include different protein and non protein moiety to work together.
Option B
<h3><u>Explanation:</u></h3>
Proteins are the polymer of amino acids which are formed after several processing. The polypeptide chains are formed when the transcripted mRNAs are translated in the Ribosomes to produce the polypeptide chains. Then they are further processed by slicings and adding and cutting of several protein parts to this main polypeptide chains and they are slightly folded by means of hydrogen bonds between the polypeptide chain atoms to give a slightly coiled structure. Now this secondary polypeptide undergoes several structural modifications by chaperon proteins which introduce different ionic, disulphide, covalent etc bondings between different parts of polypeptide chain to produce a highly coiled tertiary structure.
Now in some proteins like haemoglobin, there are the protein part i.e globin associated with haem chains, which is the Quaternary structure of proteins. It's formed when different proteins are together associated to perform a particular function.
Answer:
Throughout the summer, wind and waves cause the warming water in the epilimnion to mix deeper and deeper, slowly incorporating hypolimnetic water through the metalimnion. The ability of a lake to mix through wind turbulence is determined by the “stability” of thermal stratification.

Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.
Tinea Pedis is a foot infection that frequently caused by Trichophyton rubrum, it presents with a red scaling rash on the soles of the feet.
