Ap Biology Chapter 20 Notes

What is the function of ribosomes? What are their two components? Ribosomes are the cellular components that carry out protein synthesis. Their two components are a large subunit and a small subunit.

Surface Tension: The measure of how difficult it is to stretch or break the surface of a liquid.

Biology 102 introduces students to the concept of evolution, the principles of evolution, natural selection, and major kingdoms of living things organisms. My major is nursing and taking this course is a prerequisite and is required for my major. Taking Biology courses will help me be better knowledgeable in my chosen field. I took biology 101 last semester and we learned about cell and organisms. These are fundamentals things that someone who plans to have a career in the healthcare field needs to know. Also these courses are prerequisites for other science courses I have to take such as microbiology, human anatomy and physiology. As a future nurse these are information that will come in handy everyday. I have three years left in my undergraduate study and more

Carbohydrates: any of a class of organic compounds that are polyhydroxy aldehydes or polyhydroxy ketones, or change to such substances on simple chemical transformations, as hydrolysis, oxidation, or reduction, and that form the supporting tissues of plants and are important food for animals and people.

We will not go through the process here, but as an illustration of this “alternate splicing”, remove codons (beads) 52 - 66 from your sentence above.

7)a) You would do the Benedict’s reagent test for simple sugars and the Lugol’s solution or Iodine test for polysaccharides and starch. To test the lipids you would use the Sudan iV test and Biurets reagent test for protein.

1. Information transfer is fundamental to all living organisms. For TWO of the following examples, explain in detail, how the transfer of information is accomplished.

In eukaryotes, stored primarily in the cell nucleus. A nucleic acid using deoxyribose rather than ribose.

Experimental Method: The experimental design was sourced from the lab course manual: Setting-up RNAi With a light microscope, two live worms were located on the control plate. 180 μl of M9 buffer was mixed with 20 μl of 1M IPTG. The entire 200 μl was pipetted into the plate covering the bacteria. The plate sat for ten minutes until the liquid was completely absorbed. The worms were put under the microscope to ensure they were still alive.

The topic of cloning has always been very controversial in today’s society. Some people believe that cloning is unethical and should not be done, while others believe cloning is perfectly fine and should be done. Both of these views have many people supporting them and have many different reasons to prove their case.
