Textbook Question
Chapter 14.5, Problem 3CC
WHAT IF? DRAW IT The template strand of a gene includes this sequence: 3’-TACTTGTCCGATATC-5'. It is mutated to 3’-TACTTGTCCAATATC-5’. For both versions, draw the DNA, the mRNA, and the encoded amino acid sequence. What is the effect on the amino acid sequence?

Thank u!!
HELP PLEASE !!
In moelcular genetics, initiation is often accomplished using proteins that prevent elongation. Name and describe 3 processes where this happens, they can be in different species. Make sure to name or describe the proteins and substrates involved and how the elongation inhibition is overcome.

- 1. Create an inversion on your mini gene .. ? that results in an inversion. Sequence 5 ATGGTGCAAGATTAA 3' 3 TACCACGTTCTAATT 5' The sequence after the inversion is: 5 ATGCTTACGGATTAA 3 3 TACGAATGCCTAATT 5' Comments and help • By convention we write DNA sequences starting with the 5' end and ending at the 3' end. 4. Create mutation on the sequence on your minigene that results in an in-frame non-tandem duplication. • Also, by convention when you write double stranded sequences, the top strand is the 5' to 3' and the bottom strand 3' to 5'. 2. Generate a primer pair that is 6 base-pairs long to amplify the inversion you created, that will not amplify your wildtype mini gene. • If you are typing your answer, use the Courier font for the sequence. This allows proper alignment of the two strands. 3. Create point mutations on the sequence on your > minigene that results in: i. a frameshift, ii. a silent mutation, iii. a conservative mutation, iv. a missense, v. a nonsense mutation.arrow_forwardwhich multiple choice?arrow_forwardpls help me to do these my activity and answer properlyarrow_forward
