Carbon-14 dating method is based on the fact that
- carbon-14 fraction is same in all objects
- carbon-14 is highly insoluble
- ratio of carbon-14 and carbon-12 is constant
- All of the above
The Correct Option is C
Solution and Explanation
Age of wood $=\frac{2.303}{.693}\times T_{0.5} log\Bigg(\frac{N^0}{N}\Bigg)$
$\, \, \, \, \, \, \, \, \, \, \, \, \, \Bigg[\frac{Ratio of C^{14} / C^{12} in living wood}{Ratio of C^{14} / C^{12} in dead wood}\Bigg]$
Hence, it is based upon the ratio of $C^{14} and C^{12}$

Questions Asked in NEET exam
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :

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.
