EXTRACTION OF INVERTASE FROM YEAST AND EFFECT OF pH ON ENZYMATIC ACTIVITY Jenelle C. Faustino‚ John Gambit B. Garcia‚ Fatima S. Jusay‚ Oliver Alexander B. Lao and Eunice L. Licudine Group 4 2 E Medical Technology Biochemistry Laboratory ABSTRACT Enzymes are substances that are produced by living organisms and act as catalysts in order to speed up or chance a chemical reaction without changing itself at the end of the reaction. Invertase was extracted first from baker’s yeast. Determination

What is a Tooth Extraction? A tooth extraction is the process of removing a tooth from the mouth. The procedure may need to be done for a number of reasons. Sometimes before getting braces‚ a tooth needs to be removed in order for the teeth to have enough room to move into their proper location and order for a straight smile. In other cases‚ a tooth may need to be removed because it has decayed or has become loose due to gum disease. Removing it is the first step in stopping the pain and infection

It takes a period of 20 years for the Prunus Africana to grow to 30 meters or more. That is one reason there are only a limited number of Prunus Africana found in Kenya‚ Uganda‚ and the Democratic Republic of Congo. The extraction of pulverized‚ dark bark of Prunus Africana is the reason for high demand on these trees for production of drugs for prostate issues. The Prunus Africana is currently being harvested out of eastern highlands of Kenya in the Aberdares Mountains

DNA replication is a biological process that occurs in all living organisms and copies their DNA; it is the basis for biological inheritance. The process starts when one double-stranded DNA molecule produces two identical copies of the molecule. The cell cycle (mitosis) also pertains to the DNA replication/reproduction process. The cell cycle includes interphase‚ prophase‚ metaphase‚ anaphase‚ and telophase. Each strand of the original double-stranded DNA molecule serves as template for the production

strands of DNA double helix are separated‚ each can serve as a template for the replication of a new complementary strand‚ producing two daughter molecules each of which contains two DNA strands with an antiparallel orientation. The enzymes involved in DNA replication process are template-directed polymerases that can synthesize the complementary sequence of each strand with extraordinary fidelity. This complex leads to the local denaturation and unwinding of an adjacent A + T rich region of DNA. The interaction

Forensic DNA Profiling Forensic DNA Profiling Recent advancements in science and computer technology have allowed scientists and investigators to use genetics to aid in solving crime cases. Although there are many different types of methods used to analyze DNA‚ the general process is based upon the uniqueness of each individual’s DNA‚ much like a fingerprint. Due to this uniqueness‚ genetic evidence that matches a specific individual to a crime scene is often viewed as concrete and undeniable

Acme Minerals Extraction Company A long time ago‚ work used to be assigned only to one person and that person was in charge of doing only that task. Then‚ with the new technology innovations‚ we start seeing how companies started to trained some employees to be what they usually called “multi-tasking employees”. Since technology kept changing and became more advanced companies realized that having “multi-tasking employees” was not enough to satisfy the market demands and the production problems

Importance of DNA Typing i Outline Thesis Statement: Although having an infant’s DNA typing done at birth can effectively analyze important health information‚ it should be an individual’s given right to accept and/or decline the storage of their private information. I. Some individuals are unaware of DNA typing of infants at birth. A. An individual may be described as parent‚ or person distinguished from others by a special quality. B. Some individuals claim that DNA typing

BIOTECHNOLOGY RECOMBINANT DNA technology 1. This is a modern biotechnological advance ‚ in which a desired gene fragment can be inserted in to a cloning vector and the resulting DNA (Recombinant DNA) can be amplified in suitable host. 2. A vector can be a plasmid‚ cosmid‚bacterophage‚retroviruses‚ animal and plant viruses or artificial chromosomes like YAC‚ BAC‚or HAC.(Yeast artificial chromosome‚ bacterial........) 3. The rec. DNA produced can be amplified or cloned in a suitable vector
