I must admit, I have LOVED teaching Honors Biology. Getting weekly reports from them, though, has been a bit challenging. Hopefully next 9 weeks we will be able to bring you a more consistent flow of information from that class. As with all classes this week, it is the end of the 9 weeks. I know that the students of Honors Biology are breathing a bit easier as they dance off into the sunset of Spring Break. With the end of the 9 weeks, we concluded our investigation of all things DNA. In truth, the students did really well this unit. Most of them seemed to have a pretty good grasp of the information, and some of them might have even found it interesting. They've been working on a genetic technology project throughout the course of this unit, so look for samples of that to pop up soon. This week (2/27-3/2), we do have two week in review reports from Catherine Parker and Maria Sanchez.
In class this week we started on Unit 6. Starting off we discussed significant events in the hunt for DNA, described the basic structure of DNA, and also applied the DNA base-pairing rules. In DNA we went over the structure of DNA and that was nucleotides are connected to form a nucleic acid. We also learned the structure of a nucleotide; 5-carbon sugar, deoxyribose, phosphate, and nitrogenous base. The two strands of nucleotides wind around each other and that allows A to be paired up with T, C goes with G. Bases are held together by hydrogen bonds. We went over how scientists use restriction enzymes to cut out things. In class we learned that there are 3 types of RNA. They are mRNA, known as messenger RNA, tRNA, known as transfer RNA, and rRNA, known as ribosomal RNA. IN describing the consequences of genetic mutation, we know that we have 2 levels of mutation. The first one is a gene mutation. The second level of mutation is a chromosomal mutation. Last we talked about genetic engineering and that's making changes into the genetic code of a living organism, selective breeding, and gel electrophoresis, which is used to separate DNA fragments.
In Biology this week we did alot! We started our week off with a fun assignment, which was practicing our understanding on Translation, Transcription (mRNA, tRNA. rRNA, DNA). Also we covered Genetic Engineering which is making changes in the genetic code of a living organism. During this week we also had to take a test, of coursed we reviewed over the material a day before the test, with a Jeopardy Review. Since Biology has a VOCAT test at the end of the year we can't waste no time, so we started a new unit today. To end the week before Spring Break we got a easy assignment assigned during Spring Break which is create a family tree.
