Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
STRUCTURE:The five-carbon sugar found in DNA.
A
ribose
B
guanine
C
deoxyribose
D
helicase
Explanation: 

Detailed explanation-1: -Deoxyribose is made up of 5 carbon atoms that are arranged in a pentagonal shape. Because it only has four oxygen atoms, deoxyribose is considered a modified sugar when compared to other pentose sugars.

Detailed explanation-2: -deoxyribose, also called d-2-deoxyribose, five-carbon sugar component of DNA (q.v.; deoxyribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the DNA polymer and binds to nitrogenous bases.

Detailed explanation-3: -The five-carbon sugar in DNA is called deoxyribose, while in RNA, the sugar is ribose.

Detailed explanation-4: -DNA contains deoxyribose as the sugar component and RNA contains the sugar ribose.

Detailed explanation-5: -Ribose is a single-ring pentose [5-Carbon] sugar. The numbering of the carbon atoms runs clockwise, following organic chemistry rules.
