1. Introduction Nepal has more villages than cities and towns. More than 80% of the people are dependent on agriculture for their livelihood. Nepal is rich in forests. % of the total land is covered with forest. Majority of the rural households are subsistence farmers and rely heavily on forest products to meet their daily requirements. Fuel wood is used for cooking and heating purposes‚ fodder and grass for livestock‚ leaf litter for manure‚ and timber for constructing houses and for making agricultural

Epigenome biomarkers a. DNA methylation In the broad sense‚ epigenetics can be seen as a bridge between the genotype and phenotype‚ where the final outcomes of a locus or a chromosome can be changed without altering the underlying DNA sequence (Goldberg et al. 2007)‚ while epigenomics aims to study the location and nature of the gemonic sequences that are epigenetically modified (Fazzari and Greally 2004). Usually‚ three mechanisms have been attributed for epigenetics – DNA methylation‚ histone modification

electrophoresis machine. An electric current is run through the machine and the different sized molecules form bands on the gel matrix. In visualization‚ the gel is dyed so the results become present. This is used in modern crime labs‚ figuring out DNA‚ which plays a key role in many criminal trials. The researcher completed this experiment to figure out who committed the murder using gel electrophoresis. The researcher followed five steps in this experiment; First was placing the gel in the electrophoresis

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

DNA replication mechanism is an integral and the most important part of cell division. It is a complicated mechanism that requires a lot of steps and different enzymes. Many scientists were trying to understand the mechanism of DNA replication and its role in the transfer of the hereditary information to the offsprings. DNA replication begins with a single origin of replication that starts off the process by creating a replication bubble. In many eukaryotic cells‚ the DNA strand will have more than

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
