Question

Compare the phosphates, sugars and bases of DNA and RNA.

Answer 1

DNA is double helix, while RNAs are single stranded structure. Phosphates and pentose sugars are similar in both the nucleic acids, while the thymine is replaced by uracil in the RNA.

`#SolutionGiven`

Answer 2

Answer: The combination of phosphate, sugar, and nitrogen bases in DNA or RNA is called a nucleotide.

Step-by-step explanation:

Explanation: Nucleotides are building blocks of RNA and DNA. In RNA, nucleotide are made up of ribose sugar, a nitrogenous base which can be adenine, uracil, cytosine and guanine; and a phosphate group. The nucleotides in RNA are called ribonucleotides. The nucleotides in DNA are called deoxyribonucleotides and they contain a deoxyribose sugar, a phosphate group and a nitrogenous base which can be adenine, thymine, cytosine and guanine.
