Biology fascinates me‚ simply because we are only able to live‚ think‚ and question because of it. It is‚ quite literally‚ the foundation of our existence. The academic pursuit to understand the messy and complex logic of life‚ at the molecular‚ cellular and organismal level‚ deeply appeals to me. I am particularly interested in Biomedical Science‚ as it delves deeper into human biology‚ and applies the scientific knowledge gleaned to help with disease understanding and treatment. I was piqued by

ABSTRACT The effect of molecular weight on the rate of diffusion was measured using two tests namely: the glass tube test and the agar-water test. The set-up of the glass tube test used two cotton balls of the same size. One cotton ball is moistened with hydrochloric acid (HCl) and the other one is moistened with ammonium hydroxide (NH4OH). The two cotton balls were inserted in both ends of the glass tube. NH4OH which has a lighter molecular weight (35.0459 g/mole) diffused with a faster rate (dave=20

computer is an intrinsically dualistic entity‚ with its physical set-up designed so as not to interfere with its logical set-up‚ which executes the computation. The brain is di¡erent. When analysed empirically at several di¡erent levels (cellular‚ molecular)‚ it appears that there is no satisfactory way to separate a physical brain model (or algorithm‚ or representation)‚ from a physical implementational substrate. When program and implementation are inseparable and thus interfere with each other‚ a

RANELLE JANINE L. ASI BIO 120 S-5L EXERCISE 9. Genomic DNA Isolation & Exercise 10. Polymerase Chain Reaction (PCR) Cell and molecular biology is a science based on the various systems of a cell resulting to its regulation‚ maintenance and function. Many of these systems involve genetic information hence the study of the DNA is an essential part of this field. To able to analyze DNA‚ it must first be isolated and purified from its natural environment filled with biological molecules and compounds

DNA DIGESTION AND ELECTROPHORESIS In this experiment we will be doing a process called as DNA digestion or also known as restriction digest. A restriction digest is a procedure used in molecular biology to prepare DNA for analysis or other processing. It is sometimes termed DNA fragmentation‚ scientists Hartl and Jones describe it this way: This enzymatic technique can be used for cleaving DNA molecules at specific sites‚ ensuring that all DNA fragments that contain a particular sequence have the

Genetically modified foods use the latest molecular biology techniques and are commonly used for growing crops for human or animal consumption. GM foods can create specific characteristics of plants or animals‚ such as the ably to withstand weather conditions(temperature)‚ nutrition and they can keep
