Kinetic Molecular Theory Basic Concepts The gas laws developed by Boyle‚ Charles‚ and Gay-Lussac are based upon empirical observations and describe the behavior of a gas in macroscopic terms‚ that is‚ in terms of properties that a person can directly observe and experience. An alternative approach to understanding the behavior of a gas is to begin with the atomic theory‚ which states that all substances are composed of a large number of very small particles (molecules or atoms). In principle‚ the

THE MOLECULAR BASIS OF INHERITANCE I. History A. Discovery of “transformation” – a change in genotype and phenotype due to the uptake of external DNA by a cell 1. Griffith 1920s did experiments with Streptococcus pneumoniae (p294 fig16.2) a. took two strains of S. pneumoniae‚ one virulent‚ one not b. heat killed virulent strain‚ then mixed them with the living nonvirulent strain c. living nonvirulent strain became virulent d. nonvirulent strain took on virulent strain’s DNA became virulent

arena. I had my first glimpse at molecular biology then. But that brief introduction to molecular biology was enough to compel me to the idea that I want to spend my whole life working and conducting research on it. That passion and zeal brought me to where right now I am. I have successfully completed my masters from the Department of Genetic Engineering and Biotechnology‚ University of Dhaka. I want to note that very few universities offer courses related to molecular biology here in Bangladesh but

State Shapes 1. One distinct shape is not better than another‚ as it depends on the state’s situation. Politically‚ compact states are by far the best. The government is close to all portions of the state‚ rather than any other state shapes. For example‚ Brussels in Belgium is more politically stable‚ mainly because of its ability to interact with the other portions of the state. In other state shapes‚ there is an area where it is more difficult to communicate with. For example‚ in a prorupt state

What would you expect to happen if you added ddCTP (shown in a) to a DNA synthesis reaction in vitro in large excess over the concentration of deoxycytidine triphosphate (dCTP)? How will this affect the pattern of bands on the sequencing gel? The ddCTP lacks the OH‚ which is required for elongation

The Shape of Things Essay “Love is whatever you betray‚ betrayal can only happen if you love” (John le Carre). The play The Shape of Things by Neil Labute reminded me of this quote by John le Carre because of the reality in life and reality in the play. Beginning in a museum located in a small town‚ Adam was a shy student working at the historical facility and a conversation sparked up between him and a girl named Evelyn. As the play went on‚ Evelyn became so important to Adam that he simply

Hierarchy of Monstrous Behaviour Adrienne represents "a monster in the shape of a girl‚" (MacLeod‚ P.40) by physically demonstrating a selfish‚ emotionless and unexplainable hate towards Sophie. Adrienne leads her friend Braidie‚ who contributes on a more subtle level to this motif of monstrous behaviour. Adrienne shows her sinister leadership by constantly instigating a form of abuse towards Sophie. "Adrienne leans into Sofie so that Sofie is squished‚" (P.42) causing apparent physical harm. Mentally
