Consider the following sequence on m-RNA AUGGCAGUGCCA. Assuming that genetic code is overlap then how many number of codon may be present on this genetic code

Consider the following statements and choose the correct option :- (a) Six codons do not code for any amino-acid. (b) Codon is read in m-RNA in a contiguous fashion. (c) Three codons function as stop codons. (d) In eukaryotes the initiator codon AUG codes for methionine.

Assertion : Untranslated regions are sequences of RNA before initiation codon and after termination codon. Reason : Untranslated regions provide stability to mRNA and also increase translational efficiency.

Like the process of replication, the total DNA of an organism gets duplicated in transcription also

The following statements describe the process of translation. I. An amide linkage is formed between adjacent amino acids. II. Hydrogen bonds are formed between the anticodon and the codon.
