જનીન સંકેત માટે શું સાચું નથી?
A
તે સર્વવ્યાપી છે.
B
તે અવનત છે.
C
તે અસંશયાત્મક છે.
D
$m-RNA$ માં સંકેતો પરસ્પર જોડાયેલા (કે લગોલગ) હોતા નથી.
(AIPMT-2009)
Solution
(d) : The relationship between the sequence of amino acids in a polypeptide and nucleotide sequence of $DNA $ or $mRNA$ is called genetic code. The genetic code is continuous and does not possess pause after the triplets. So a codon in $mRNA$ is a noncontiguous fashion. If a nucleotide is deleted or added, the whole genetic code will read differently.
