The value of amu is which of the following?
Updated On: Jul 28, 2022
- $1.5 \times 10^{-24} \,kg$
- $1.66 \times 10^{-24} \,kg$
- $1.99 \times 10^{-23} \,kg$
- $1.66 \times 10^{-27} \,kg$
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
amu represents atomic mass unit. It is used in place of unified mass unit.
$1 amu =1$ avogram $=1$ aston $=1$ dalton
$1 amu =\frac{1}{12} \times$ mass of $C -12$ atom
$=\frac{1}{12} \times 1.9924 \times 10^{-23} g$
$=1.66 \times 10^{-24} g =1.66 \times 10^{-27} kg$

Nucleic acids
Nucleic acids are explained as long-chain polymeric molecules, where the monomer (the repeating unit) is referred to as the nucleotides. Thus many times nucleic acids are referred to as polynucleotides. The two main kinds of nucleic acids are-
Deoxyribonucleic Acid (DNA)
Chemically, DNA is a composition of a pentose sugar, phosphoric acid, and some cyclic bases that have nitrogen in them. DNA has β-D-2-deoxyribose in it, in the form of the sugar moiety.
Ribonucleic Acid (RNA)
The RNA molecule is a composition of phosphoric acid, a pentose sugar, and some cyclic bases containing nitrogen. The sugar moiety inside RNA molecules is β-D-ribose.
