DIFFERENCE BETWEEN INITIATION & TERMINATION CODON

DIFFERENCE BETWEEN CODON & ANTICODON

Consider the following statements : Assertion (A) : Amber codon is a termination codon . Reason (R ) : If in a m-RNA, a termination codon is present, the protein synthesis stops abruptly whether the protein synthesis is complete or not. Now select you answer from code given below :

Anticodon present on tRNA complementary to initiator codon AUG of mRNA is

Assertion. A single mRNA strand is capable of forming a number of different polypeptide chains. Reason. The mRNA strand has terminator codons.

Assertion : A monocistronic mRNA can produce several types of polypepitude chains . Reason : The terminator codon is present on the mRNA.

Select the incorrect statement (s) : 1. Six codons do not code for any amino acid. 2. Codon is read in m-RNA in a contiguous fashion. 3. Three codons function as stop codons. 4. The initiator codon AUG codes for methionine
