Question

a) Transcribe and translate this sequence of DNA (write the mRNA sequence and protein code) TACATGCCG TTTCAG GGG TTAGGC GCGAAATGCATC mRNA: Protein: b) What happens if I insert an "A" at the 9* nucleotide position in the original sequence given? What is the protein message now? modified DNA: mRNA: Protein: c) Which enzyme was used during transcription? What is the machinery/organelle responsible for building the protein? I

Answer 1

Caly TACATGCCG TITCAG GGG TTA Ĝ G C GCG AAA TGCATC. Aften than scription of the DNA sequence, the new mRNA sequence would be mRNA: AUGU ACGGC AAA GUC CCC AAU CCG CGCUUU ACGUAG. After translation of the mRNA sequence, the new proton seguence would be - Proton :- Met - Tyre - Gly-Lys Val - Preo - Asn - Preo - Ang Phee Thre,

(b)% of we inseret an "A" at the 9th position, the original sequence woolol become : DNA:- TAC ATG CCG ATT I CAG GGG ITA GGC GCG AAA TG CATC. The mRNA would be :- AUG UAC GGCUAA A GUCCCC AAU,CCGCGCOLUACGUAG, G The new protein would be Met - Tyre-Gly. ( The protein sequence will stop at Gly due to codon UAA). presence of stop
