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) 90Explanation / Answer
7. in order to initiate transcription, you need
A. a core promoter sequence must be present.
C. RNA polymerase must be present.
8. after synthesis, eukaryotic pre-mRNA undergo extensive modifications to form mature mRNA, including
Capping, polyadenylation, and splicing.
All of the above.
9. correct genetic sequence
A. promoter, initiation code, gene, terminator code, terminator region.
10. anticodon for start codon- 5’-CAU-3’
Anticodons for stop codons- 5’-UUA-3’, 5’-UCA-3’, and 5’-CUA-3’
11. site of transcription- (Pyrimidine-2,A,pyrimidine-4) 25 bases after TATAAA sequence (in eukaryotes)
The site of splicing-at both the sides of introns. usually GUat 5’-splice site and AG at 3’-splice site.
The site of capping- 5’ end of mRNA (7-methyl guanosine is added to 5’-end)
The site of translation- starts at AUG codon.
12. correct statement- a given amino acid has more than one codon.
13. transcription and translation of a gene composed of 30 nucleotides would form a protein containing no more than 10 amino acids.
(3 nucleotides constitute a codon that codes for one amino acid)
14. transcription occurs along DNA template.
