EleoNora [17]
<span>Decrease. Net filtration is the equilibrium force that can be measured in the capsular space of the renal corpuscle. This determines how much water and small dissolved solutes leave the blood in the glomerulus. The equation for net filtration is: (IFOP); NFP = GBHP - (CHP + BCOP). The Net Filtration is generally around 10 mm Hg.</span>

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.

Individuals with premutation length repeats in FMR1 may have some of the phenotypes of Fragile X but not others, which is ______
IRISSAK [1]

Answer:

variable expressivity; incomplete penetrance

Explanation:

In genetics, variable expressivity refers to the fact that individuals having the same alleles/genes/genotype associated with a particular genetic condition may exhibit different clinical features of this condition. In general, variable expressivity is due to the combination of both genetic and environmental factors. An example of variable expressivity is the Marfan syndrome, where all individuals with this disorder have a dominant mutation in the FBN1 (fibrillin 1) gene and show different degrees of the same phenotype. Moreover, incomplete penetrance (also known as reduced penetrance) refers to the complete absence of a genetic trait or disease in individuals having alleles/genes/genotype associated with the condition. In consequence, individuals with incomplete penetrance do not develop features of the disease. An example of incomplete penetrance is given by those individuals with mutations in BRCA1/BRCA2 genes (associated with an increased risk of developing breast cancer) that do not develop cancer.

cricket20 [7]
Retrotransposons are class of transposons that contain long terminal repeats and code for an enzyme that synthesize DNA using an RNA template. It is found in all eukaryotes but absent in prokaryotes. About 42% of human genome is made up of retrotransposons. They are particularly abundant in plants, in maize 49-70% genome is made up of retrotransposons.
