What is the name of the sugar in the mrna nucleotides?

The answer is ribose.

mRNA is actually messenger ribonucleic acid. As any other RNA (ribonucleic acid) it consists of a phosphate group, sugar ribose, and nucleobases (adenine, uracil, cytosine, guanine). So, it is called RIBOnucleic acid because it consists of sugar RIBOSE.
Take for example DNA - deoxyribonucleic acid. It is called DEOXYRIBOnucleic acid because it consists of sugar DEOXYRIBOSE.

Twins are born minutes apart, not a year apart. fraternal twins are no more closely related genetically than ordinary siblings born a year apart. they just happen to be born at the same time. identical twins result from a single fertilized egg dividing and separating early in gestation. although identical twins are more similar to each other than other siblings, there is some research to suggest they are not 100% the same. you and your brother share very similar dna because you have the same parents, and you look the same. i'll bet you resemble one or both of your parents, and likely a grandparent or two as well.
