The correct answers are option A. "are specific nucleotide sequences", C. "are located in a specific place on a chromosome", and D. "determine the traits of an organism".
Explanation:
Genes are specific nucleotide sequences comprised of DNA that are translated into bioactive elements such as proteins. Genes are located at specific places on a chromosome, and a chromosome can contain hundreds to thousands of genes. Genes determine the traits of an organism, which are often the result of the action of more than one gene.
The correct option is D. Genes determine the trait of an organism.
Explanation:
Option D is correct because genes can be described as the hereditary molecules that determine the characteristics of a person.
Option A is false because each gene is made up of different nucleotide sequences.
Option B is false because genes do not occur as the same number of chromosomes. Rather, there are many genes present on a single chromosome.
Option C is false because all genes are not located in a specific location. Each gene has its specific location on the chromosome which is known as its locus.
Option E is false because genes are not units of RNA. Genes are made up of DNA.

The high concentration of urea causes unfolding of protein and thus results in loss of function of a protein. The urea interacts with the protein and prevents the folding of a protein.
During oxidation, the disulfide bonds that are required for proper functioning and stabilization of protein are formed, while in the presence of urea, the disulfide bonds are not positioned correctly. The protein oxidation results in covalent modification of a protein that results in the change of physical and chemical properties of a protein.
The change of physical and chemical properties of protein after oxidation and in the presence of urea cannot be modified even after the removal of urea. Thus, protein does not fold properly.
Hence the right answer is "disulfide bonds are not positioned correctly rather than week bonding interaction"
