Question

Write the differences between(i)DNA and RNA (iii)alpha form of glucose ane beta form of glucose
​

Answer 1

Explanation:

different between rna and dna:-

rna contains the sugar of ribsoe or dna different sugar de oxyribose

rna nucleo base but dna containe thymine.

alpha glucose and beta glucose are two cyclic hemiacetal forms of glucose which also different only in the configuration of hydroxyl group (-OH) at anomeric carbon.

some isomere are called anomers.alpa d -glucose and beta -D-glucose are stereoisomers, they differ in 3-dimensional configuration of atoms/groups.

Answer 2

Answer:

They differ only in the direction that -H and -OH groups point on carbon 1 (See the jmol images below). When alpha-glucose molecules are joined chemically to form a polymer starch is formed. When beta-glucose molecules are joined to form a polymer cellulose is formed.
