Question

how does nuleoside and nucleotides are formed?

Answer 1

Answer:

nitrogen base + pentose sugar=nucloside........

nitrogen base +pentose sugar+phosphorous group=nuclotide

Answer 2

Nucleoside and Nucleotide formation

Explanation:

Formation of nucleoside:

• When sugar is attached with the nitrogenous base it leads to the formation of the nucleoside.
• In the case of DNA, the nucleoside is formed by the addition of nitrogenous bases such as adenine or guanine or cytosine or thymine with deoxyribose sugar.
• In the case of RNA, it is formed by the addition of nitrogenous bases such as adenine or guanine or cytosine or Uracil with ribose sugar.

Formation of nucleotide:

• When sugar is attached with a nitrogenous base and a phosphate group, it leads to the formation of nucleotide.

• In the case of DNA, the nucleotide is formed by the addition of nitrogenous bases such as adenine or guanine or cytosine or thymine with deoxyribose sugar and a phosphate group.
• In the case of RNA, it is formed by the addition of nitrogenous bases such as adenine or guanine or cytosine or Uracil with ribose sugar and a phosphate group.
