Assertion : $UAA,\,UAG$ and $UGA$ terminate protein synthesis.
Reason : They are not recognised by $tRNA$.
Initiating codon in eukaryotes is
Choose correct pair.
Column $– I$ | Column $– II$ |
$(A)\; AUG$ | $(1)$ Phenyl alanine |
$(B) \;UAA$ | $(2)$ Methionine |
$(C)\;UUU$ | $(3)$ Tryptophan |
$(D) \;UGG$ | $(4)$ Stop |
How many codes are blank
In $mRNA, AUG$ is the initiation codon and $UAA, UAG$ and $UGA$ are termination codons, therefore polypeptide cannot be synthesized beyond any of these triplets to the end of $mRNA$. Then which one of the following $mRNA$ can be translated completely
