We went over the virus concept map and discussed the lytic and lysogenic cycles. We then used the computers to view the Campbell activity 18.4 (lac operon) while answering the questions handed out yesterday. The homework is as follows: Read 18.3, complete the notes for objectives 13-18 and complete interactive questions 18.4 and 18.5. There will be a 40 point assessment covering the material from Chapters 17 and 18 next Tuesday.

We used the computers today to view and write about 2 simulations - about a retrovirus and a prokaryotic gene control process called an operon. The web site for the former is to the right and for the latter is on the Campbell site (18.4 activity). The homework is to continue the note pages (from yesterday) for objectives 8 through 12 as you are reading pages 342 - 346.

We wrapped up chapter 17 by looking at 2 mutation animations (showing frameshift and nonsense mutations). We then began work on chapter 18 with the objectives and the chapter 18 study guide. We spent the remainder of the period reading the beginning of chapter 18 and taking notes about the objectives. By tomorrow we should have the following completed: Reading pages 334 -342, notes for objectives 1 -7 and interactive q's 18.1 - 8.3

Monday 1/25/10 - In Class and Homework

We reviewed the process of protein synthesis by going through the campbell animations (overview, transcription, mRNA processing and translation). We also went through many of the study guide interactive questions (Chapter 17). We then passed back the chapter 15 & 16 quiz and explained there will be a requiz possibility, after some additional practice (and mastery). The homework is to review chapter 17 - connecting to the objectives.

We wrapped up our protein synthesis Lab today (lab sheets were turned in). The homework is to read the remainder of chapter 17 (pages 327 - 331) and to complete the remaining interactive q's from the study guide

Thursday, January 21st -In Class and Homework

we began our protein synthesis lab (this is a "2 in 1" lab - both an analogy {sentence} lab and a simulation {building a polypeptide}). We used props simulating a DNA strand, a mRNA strand, tRNAs, a ribosome and amino acids. The homework is to review sections 17.2 - 17.4.

Wednesday January 20th, 2010 - In Class and Homework

(No school for students Monday and Tuesday). We used the computers in class to observe and write notes about animations dealing with protein synthesis (specifically - transcription and translation). Handouts included a chapter 17 objectives sheet, a note sheet to describe the animations and a chapter 17 study guide. The homework is to read sections 17.3 and 17.4 and to complete the study guide questions 17.1 - 17.4
