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.
Sorry if I'm wrong but if I'm correct its pupa
Answer:
Explanation:
Cells divide and reproduce in two ways, mitosis and meiosis.
Mitosis results in two identical daughter cells, whereas meiosis results in four cells.
<u>Keys differences and similarities between the two types of cell division.</u>
Mitosis Meiosis
cells created: two daughter cells four daughter cells
Ploidy Creates diploid daughter cells Creates haploid daughter cells
Genetics Daughter cells are Daughter cells are . . genetically identical genetically different
<em>Why is there a meiosis II but not mitosis II?</em>
<em>Meiosis II is generally regarded as being very similar to mitosis, except for the presence of two parent cells, instead of only one. In both meiosis I and II, cytokinesis occurs, and there are two daughter cells per parent cell.</em>
