The main molecule found in nucleus is called DNA(deoxyribonucleic acid). This molecule is made of subunits called nucleotides. A nucleotide is made of a nitrogenous base that can be adenine, thymine, guanine or cytosine; a five carbon sugar called deoxyribose and a phosphate group. This molecule controns protein synthesis. Proteins are crucial to the cell's function.

Explanation:
Dominant alleles are always expressed when they are present. Recessive alleles are masked by dominant alleles.
Therefore, two copies of a recessive allele are required to show the recessive trait. Either one or two copies of a dominant allele produces the dominant trait.
Therefore, for dominant brown eyes, BB or Bb gives brown eyes, bb gives blue eyes.
For recessive long tails, tt gives short tails, TT and Tt gibe long tails

Explanation:
Age-related macular degeneration is an eye related disease which causes our macula to degenerate. It leads to blurred vision which further impacts our abilities like sewing, reading and driving adversely. It can be cured by intake of vitamin C and carotenoids in appropriate amount. Cataract is another disease related to eyes which most commonly occurs in old age people. In this disease, the eye lenses appear cloudy because of the changes in the eye lens tissue. Beta carotene and vitamin C both are very helpful in restricting cataract.
