Protein Synthesis Notes If DNA’s shape is altered it can’t function properly. RNA is more flexible so changing the shape changes the function‚ which is wanted. Any shape of RNA can become another. Three shapes/functions of RNA: -mRNA: messenger (linear_____) -rRNA: ribosomal (large and like a globe) More stable than mRNA. -tRNA: transfer (shaped like t) If you flatten this it becomes mRNA. Hydrogen Bonds ………………………………. Protein Synthesis Overview- Two Processes: Transcription- synthesis of mRNA

Evolution Lab “Evolution by Natural Selection” The object of this experiment is to determine how changing the size of the beak of a finch will affect the population as well as the growth rate of the finch’s beak. The reason for the experiment is to evaluate evolution and how it affects the finch’s population‚ and how natural selection is always present in life. In this experiment I will show that the finch will continue to evolve until its beak has reached the optimal size for sustaining

Angelica Mendoza May 20‚ 2013 For almost any situation in life‚ it’s important to make progress; rather than staying the same‚ which is an idea showed greatly in the play Inherit the Wind by Jerome Lawrence and Robert E. Lee. Throughout the play‚ Drummond‚ the defense lawyer‚ is defending Cates‚ a schoolteacher‚ who is accused of teaching Evolution in a public school‚ which is illegal at the time. Living in a town filled with extremely religious people‚ Cates and Drummond obviously know that

Presidential elections have been going on in our county for hundreds of years. Most of them took place before television even existed. Television was invented witch color in the early 1960’s and that is when the first televised presidential debate took place (document D). Presidential debates‚ from the start have always been a pretty big hit on the television but ever since 1988‚ the debates ratings have been below 40. I think that this is because more interesting television programs have come

enetics is the study of heritable changes in gene function that do not involve changes in the DNA sequence. Involves a methylation composition that affects the communication and response between cells and DNA. We all know DNA is your genetic makeup passed down from generation to generation. However‚ our DNA is intertwined with a protein known as histone. The bond between histones and DNA can vary along the DNA strand. This is caused by mythol group composition that cause the histones and DNA to coil

Traditional way of synthesizing sensitive rhodamine starts with rhodamine B‚ amino compound‚ and some alkali additive in the presence of weak base. However‚ for RH-PY‚ the stearic hindrance of pyrene slows the reactivity‚ and the reaction does not go to completion. Therefore‚ the reaction procedure was modified as follows. First‚ HATU and DIPEA were used to activate the carboxyl group of rhodamine B‚ then the activated rhodamine B was reacted with 1-aminopyrene. By introducing this method‚ the reaction

The dust in our homes and the air we breathe harbor a complex stew of chemicals. Some‚ like oxygen‚ sustain life. Others are pollution stemming from things like car exhaust or from tiny scraps of household products. A pair of new studies adds a level of much-needed detail about exactly how widespread such toxic exposures can be. A new analysis‚ published Wednesday in Environmental Science & Technology‚ reaffirmed that consumer product chemicals including phthalates‚ phenols and flame retardants are

Neuroplasticity is the process where the brain learns to acquire new skills or adapt to different experiences. It is a useful component for the mental capacity of a human being especially during their performances in the day to day lifestyles. This process involves changes in the brain where it includes replacement of injured tissues leading to an addition of neurons in the brain. After that‚ the reorganization of the information processing areas within the brain systems occurs. Whenever a brain

Introduction In this lab‚ caproic acid was synthesized in a multi-step process that involved the synthesis of three intermediates – diethyl n-butylmalonate‚ potassium n-butylmalonate‚ and n-butyl malonic acid respectively. An IR was used to characterize the starting material‚ n-bromobutane‚ and the first intermediate‚ diethyl n-butylmalonate; while IR and NMR were used to characterize the final product‚ caproic acid. Reactions‚ Mechanism and Theory Caproic acid a.k.a n-hexanoic acid is a carboxylic
