And a synonymous mutation does not result in a different amino acid?
Are both of these considered examples of “point” mutations?
I am coaching for “Gene-ius”. I recently got the new karyotype model for practice and noticed that we were given 72 chromosomes on the magnetic sheet to cut out, however, on the content sheet it says that we are supposed to have 75 chromosomes. I was just wondering if this was a typo on the sheet, or if I am missing a piece of the set? Thanks
· Magnetic chromosomes (ideograms of G-banded human chromosomes) – The kit initially comes with one magnetic sheet containing 72 chromosomes (3 each of autosomes 1 to 22, 3 X’s and 3 Y’s). Individual chromosomes will need to be cut out of this sheet (easy to do with a pair of good scissors). Extra chromosomes are included in order to simulate trisomies and in case of the loss of a chromosome.
Q: Hello, First time coach here, fumbling my way through. I am watching the GENE-ius workshop and when answering question re: using the Codon chart, 13:55 into the workshop video, there is question about a mutation in the gene sequence. The amino acid sequence is identified as “methionine, leucine, tryptophan, tryptophan, glutamic acid, glutamic acid, stop.” The way I am reading it, there is only one glutamic acid before the Stop. Could you please check that for me? I just want to make sure I am understanding it correctly and that I teach the kids correctly. I think there is an error in the answer given. If I am mistaken, then I apologize, and I will need some further clarification on how to read the sequence. Thank you!!
A: Thank you for your comment. You are correct. The correct amino acid sequence resulting from the mutation is Met-Leu-Trp-Trp-Glu-Stop. I am unable to modify the video from last year but the corrected pdf of the PowerPoint used during the presentation has been posted here.
