5.Molecular Basis of Inheritance
normal
Genetic codes are
A
Similar in $mtDNA$, virusus, bacteria and eukaryotes
B
Different in viruses and bacteria
C
Different in $mtDNA$
D
Different in $mtDNA$ and bacteria
Solution
(c) Genetic codes are different in mt $DNA$ i.e., $AGG$ and $AGA$ code for arginine but function as stop signals in human mitochondrion.
$UGA$, a termination codon, corresponds to cryptophan while $AUA$ $(codon for isoleucine)$ denotes methionine in human mitochondria.
