10:01 Q.10. What are the anti-codon for start codon and stop codons? (hint read the question carefully) 2 Q11. What are sites of transcription, splicing, capping and Q. 12. Which of the following statements are correct? A) agiven amino acid has more than one codor B) each codon specifies more than one amino acid C) the first two bases specify the amino acid D) the genetic code is not degenerate E) all of the above F) none of the above Q.13. Transcription and translation of a gene composed of 30 nucleotides would form a protein containing no more than amino acids. A) 10 B) 15 C) 60 D) 90 Q.14. Transcription occurs along a template forming an in the direction. 1 A) 5 to 3; 5 to 3 B) 5' to 3; 3' to 5' C) 3to 5; 5 to 3 D) 3' to 5; 3' to 5 Q. 15. A geneticist isolates a gene for a specific trait under study. She also isolates the corresponding mRNA. Upon comparison, the mRNA is found to contain 1,000 fewer bases than the DNA sequence. Did the geneticist isolate the wrong DNA? A) yes, mRNA is made from a DNA template and should be the same length as the gene sequence B) yes, the mRNA should contain more bases than the DNA sequence because bases flanking the gene are also C) no, the final mRNA contains only exons, the introns were D) no, the mRNA was partially degraded after it was removed transcribedExplanation / Answer
Answers:-
10:- Start codon and stop codon are present on mRNA and each tRNA has an anti-codon which can base pair with codon.
There is only one start codon - AUG
Its Anti-codon is - UAC
There are 3 Stop codons :- UAA , UAG , UGA
Their anti-codons are :- AUU , AUC , ACU
11:- Site for transcription - Transcription is the process of synthesis of RNA from the DNA template occur in cell's nucleus.
Site for capping and splicing:- 5' capping and splicing of pre mRNA occur in cell's nucleus before RNA is translated.
Site for translation:- Translation is the process in which protein is synthesis from mRNA occurs in cell's cytoplasm.
12:- F: none of the above.
Reason:- Every codon is specific for only one amino acid.
The genetic code is degenerate.
There is tripple base set for one amino acid.
It's not confirm that given amino acid has more than one codon as there are few amino acids which have more than one codon but not all amino acids have more than one codon. So all statements are false and hence F option is correct.
13:- A) 10
14:- C) 3' to 5'; 5' to 3'
15:- C) no, the final mRNA contains only exons, the introns were removed.
