Fri-Day 2
AP Chem- we went through our REDOX (not acid-base!) titration lab, drawing out the equipment used, reactions involved, and proper techniques performed.
This lab is due Thursday the latest but you should finish it this weekend because we will be deep into the next unit by Wednesday and you will have to focus on that hw then.
Continued success in the second quarter! So far, the gas unit exam is looking quite good; the few exceptions involve NOT identifying and using keywords in the question, in which case you cannot possibly answer the question that was asked, and also, not labeling the substances involved, which resulted in calculation of the quantity of the wrong substance. Please heed the written helpful rules that appear at the end of every test (but that won't be there for you on the AP exam, by which time you'll do them automatically, of course).
Bio 6- Friday's notes and worksheet answers are posted.
We discussed the various mutation types and the effects that they ultimately have on the proteins formed and the altered traits or lack of a given trait that can be caused by these mutant shaped proteins.
We will finish our protein synthesis lab discussion and do unit test review on Monday.
Bio 7/8- Friday's notes and worksheet answers are posted.
We discussed the various mutation types and the effects that they ultimately have on the proteins formed and the altered traits or lack of a given trait that can be caused by these mutant shaped proteins.
We drew out and saw that "silent" mutations, though they involved a substituted nucleotide/slightly changed base sequence in the DNA, do not cause a different protein to be produced or coded for. This is because, in a silent mutation, the mutated codon codes for the SAME amino acid in the protein/polypeptide chain. There are only 20 different amino acids BUT there are 64 different DNA codons (triplet combinations of A,T,G,and C) so some of the DNA codons code for the SAME amino acid.
