Answer:
The correct answer would be option D.
Explanation:
Pollen of a plant is a gamete, that contains half of the alleles are required to produce the plant. Pollen fuse with stigma and complete the required alleles or genetic information.
Possible combinations in pollen would be one allele from each trait in every form either dominant or recessive. So ST, St, sT, st. would be the correct possible genetic combination present in a single grain.
Thus, the correct answer is option D.
The sequence of amino acids/bases
Answer:
Amino acids are the building blocks of life and are encoded by DNA. Enzymes and structural proteins are made of amino acids, and are used as precursors for other important biomolecules in the body. In addition, many different industries ranging from pharmaceuticals to the food industry rely on amino acids.
Answer and Explanation:
The regular synthetic denaturant of proteins is urea. The high grouping of urea causes unfolding of protein and accordingly brings about loss of capacity of protein. The urea communicates with the protein and counteracts collapsing of protein.
During oxidation, the disufide bonds that are required for legitimate working and adjustment of protein are shaped, while in nearness of urea, the disulfide bonds are not situated effectively. The protein oxidation brings about covalent adjustment of protein that outcomes in change of physical and substance properties of protein.
The difference in physical and chemical properties of protein after oxidation and in nearness of urea can't be altered even after expulsion of urea. Along these lines, protein doesn't crease appropriately.
