Question

Nucleotides have a nitrogenous base attached to a sugar at the:

Answer 1

Answer:

Explanation:

→ A nucleotide consists of three things: A nitrogenous base, which can be either adenine, guanine, cytosine, or thymine (in the case of RNA, thymine is replaced by uracil). A five-carbon sugar, called deoxyribose because it is lacking an oxygen group on one of its carbons.

Answer 2

Answer:

Attached sugar at C-1 portion

Explanation:

• The nitrogenous chemicals known as nitrogenous bases, or nucleobases, are a crucial component of nucleotides.
• The building blocks of DNA and RNA are called nucleotides, and each one consists of a sugar, a nitrogenous base, and a phosphate group.
• Adenine, guanine, cytosine, uracil, or thymine are the nitrogenous bases present in the DNA.
• These nitrogenous bases are joined to the C1' of deoxyribose via a glycosidic link. A nucleoside is a form of deoxyribose that is joined to a nitrogenous base.
• A nucleotide is a nucleoside that has a phosphate group connected to it.
