Which of the following is the main difference between DNA and RNA?

✅Explanation:
-DNA and RNA are both nucleic acids, but they have some key differences. One of the most important differences is their structure. DNA is a double-stranded molecule, while RNA is a single-stranded molecule. This difference in structure has a number of implications for the functions of DNA and RNA.
-DNA is the genetic material of all living things. It stores the genetic information that is used to build and maintain cells. DNA is found in the nucleus of cells, where it is packaged into chromosomes. When a cell divides, the DNA is copied so that each new cell receives a complete set of genetic information.
-RNA is used to translate the genetic information in DNA into proteins. Proteins are the building blocks of cells and they carry out a wide variety of functions. RNA is found in the cytoplasm of cells, where it is associated with ribosomes. Ribosomes are the organelles that synthesize proteins.
-The other options are also differences between DNA and RNA, but they are not as important as the difference in structure.
-DNA has T, while RNA has U. This is true, but it is not a major difference. T and U are both pyrimidine bases, and they can form hydrogen bonds with each other.
-DNA has genetic function while RNA, generally, has non-genetic functions. This is also true, but it is not a major difference. RNA does have some genetic functions, such as in the regulation of gene expression.
-DNA has 2'-deoxyribose, while RNA has ribose. This is a minor difference. The presence of a hydroxyl group on the 2' carbon of the sugar molecule makes RNA more susceptible to hydrolysis than DNA.
