Consider the following statements (A). r-RNA provides the template for synthesis of proteins (B) tRNA brings amino acids and reads the genetic code (c ) RNA polymerase binds to promother and initiates transcription (D) A segment of DNA coding for polypeptide is called intron

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.

Consider the following statements with respect to translation. A. Translation refers to the process of polymerisation of ribonucleotides. B. The site of translation (protein synthesis) is ribosomes. (D) An m-RNA also has untranslated regions (UTR) that are not translated. Of the above statements :

Which of the following statements regarding transcription are correct? Br a. Transcription governs the principle of complementarity. Brb. If both strands of DNA act as a template, they would code for RNA molecule with same sequences. Br c. Double stranded RNA formed after transcription promotes RNA from being translated into protein. br d. Like the process of replication, the total DNA of an organism gets duplicated in transcription also

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

Select the incorrect statement (a) Six codons do not code for any amino acid (b) Codon reading of mRNA is contiguous (c) Three codons function as stop codons (d) Initiator codon AUG codes for methionine

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 :
