depending on the way the introns are removed‚ and if there are different amino acids produced during translation in the ribosome‚ then there will be unique proteins created‚ too. This allows there to be more types of proteins in an organism than types of genes in an organism’s genome. Repressor proteins can influence the regulation of protein synthesis by binding to operators (the segments of DNA that act as switches to either allow or prohibit RNA polymerase to create mRNA strands) in an operon.

Shabnum Hamidi 11/14/12 Period 2 CST Synthesis Reflection CST & the Criminal Justice System “I am convinced that imprisonment is a way of pretending to solve the problem of crime. It does nothing for the victims of crime‚ but perpetuates the idea of retribution‚ thus maintaining the endless cycle of violence in our culture. It is a cruel and useless substitute for the elimination of those conditions--poverty‚ unemployment‚ homelessness‚ desperation‚ racism‚ and greed--which are at the

Module 2 Section 2 EXPERIMENT: DNA & Protein Synthesis Exercise 1 – Modeling DNA 1. List the four bases which are found in DNA. (1 pt) The four bases found in DNA are cytosine‚ adenine‚ guanine and thymine. 2. Fit any six nucleotides together to form a row‚ then list the six nucleotides in the order you used them. Work with your model pieces and try fitting the bases together to make a double strand as shown in Figure 9 of the lab manual. Which nucleotides form

AP BIOLOGY EXAM ESSAY (FREE RESPONSE) QUESTIONS General directions: Answers must be in essay form. Labeled diagrams may be used to supplement discussion‚ but in no case will a diagram alone suffice. It is important that you read each question completely‚ and answer each section of the question. When giving examples‚ the first ones you give will be the ones graded. (if two examples are asked for‚ and you write about 4‚ make sure the first two are the best ones; they are the only ones counted

AP Biology Summer Assignment Chapter 50.1: An Introduction to Ecology and the Biosphere Ecology is the scientific study of how organisms interact with the environment. When studying Ecology scientists want to know‚ where organisms live‚ why they live there‚ and how many are there. Ecology and environmental biology both stem from Darwin’s interest and observations upon the distribution of organisms and how they adapted to their specific environment. Darwin concluded that the environment interacting

in complexity. The most distinct difference is that Eukaryotic cells have a true nucleus bound by a double membrane. Prokaryotic cells do not have one. Another difference is despite the fact they both have DNA‚ eukaryotic DNA is complexed with proteins called histones and is organized into chromosomes. Prokarytoic DNA is naked‚ meaning it has not histones associated with it‚ and it is not

The giant amoeba is 5000 times larger than the smallest bacterium. 9. Prokaryotic and eukaryotic cells carry out the functions required for living‚ and both contain cytoplasm as well as cell membranes. Eukaryotic cells contain organelles and have a nucleus‚ whereas prokaryotic cells do not. 10. Eukaryotic;

AP Biology Summer Summaries There are many differences between proximate and evolutionary causes and explanations on why we are such easy targets for diseases. The proximate explanations are described by its anatomy‚ physiology‚ and biochemistry. Evolutionary explanations go into detail on what would happen if we didn’t have the genes that cause us to get sick. Proximate causes look for what genes it is made up of and how it works. Evolutionary causes are why natural selection hasn’t eliminated
