Answer:
<h2>URIC ACID </h2>
Uric Acid Uric acid is a compound similar to purines found in nucleic acids. It is water insoluble and tends to form a white paste or powder; it is excreted by birds, insects, and reptiles.
If you were able to look very closely at a portion of dna and find methylated histones, you would be looking at a region of inactive chromatin.
- Histone methylation is the process by which methyl groups are added to the histone protein amino acids, which create the nucleosomes around which the DNA double helix coils to form chromosomes.
- Histone methylation is the addition of one, two, or three methyl groups to certain amino acids within a histone protein. Histones are coiled around DNA in the cell nucleus.
- These findings collectively imply that DNA methylation can be either active—as a probable contributor to levels of gene expression variation—or passive—as a result of or a separate indicator of gene expression levels.

TB. It is open to change.he thing about science is that a discovery may be made today and written up but by tomorrow something else is found that edifies what was found or proves it incorrect or make it obsolete. .Therefore the answer is <span>B. It is open to change</span>
The correct answer is option (A) it is a sex-linked dominant allele.
Pedigree analysis helps to determine the different modes of inheritance like the dominance, recessive, sex-linked, autosomal, mitochondrial and others. It helps in knowing the probability of affected offsprings in a cross.
In a sex-linked dominant inheritance, the father passes their X chromosome to daughters only. Of his daughters, 100% percent will have the inheritance as daughters inherit their father's X chromosome. Mother passes her X chromosome to both the sons and daughters or it is passed on to the offspring irrespective of their gender. Of her sons and duagters, 50% will have the inheritance.
In the pedigree of a particular inherited trait given above, the father passes the trait in the first generation to all his daughters and none of his sons. These daughters to half of their children regardless of the gender. Hence, it is a sex-linked dominant allele inheritance.
