Bacterial artificial chromosome (BAC) is a major breakthrough in genomic studies as it facilitates genetic sequencing of larger genomes, such as the human genome, in comparatively less time at a much lesser cost. Mechanism of genetic cloning: Genetic sequencing is the process in which DNA...

Definition of Yeast Artificial Chromosome (YAC) Libraries Yeast Artificial Chromosome libraries are made by the systemic insertion of series of large human DNA fragments into a yeast strain capable of replicating the DNA insert truly, through multiple generations. The resulting organisms, when maintained under tightly...

Artificial chromosomes are one of the major determinants of the successes made in the field of cloning and yeast artificial chromosomes (YAC) are one of its many forms. Among the other forms of artificial chromosomes, bacterial artificial chromosomes, phage artificial chromosomes and p1-derived artificial chromosomes...

What are amino acids? Amino acids are nitrogen containing organic molecules that can join together in chains called (poly-peptides) and form complex proteins. There are 20 basic amino acids of which 8 are essential (they must be obtained from food), and 12 are non-essential (the...

What are fatty acids? Essential fatty acids (EFAs) are fats that the body cannot produce. They´re important nutrients necessary for health; and are present in every healthy cell in the human body. They´re responsible for normal function and growth of the cells, nerves...

Solid, liquid and gas are called Phase, and they characterize an arrangement of atoms/molecules. Besides arrangement, all phases of a substance are made of the exact same atoms/molecules. Phase and their change depends on the weak attractive force between atoms/molecules and the distance between them...

In the realm of biochemistry, 'metabolism' comprises two distinct sets of pathways: anabolism, or synthesis; and catabolism, or break down. In humans, twenty amino acids serve as the building blocks of all proteins. Amino acids consist of a central carbon bonded to an NH2 group...

Dietary protein intake is critical to the maintenance of the body. Protein that people eat (such as meat and dairy products) gets digested and broken down into much smaller, simpler components, which are then re-assembled into one of many different things. Without sufficient dietary protein...

In humans and most other animals, dietary proteins cannot be absorbed in an intact form. They must be broken down into amino acids by enzymes secreted in pancreatic juice as well as those within the enterocytes lining the small intestine. The enzymes that accomplish this...

Bioluminescence is used in scientific research every day. It helps scientists study the genetic code and look for ways to repair genetic damage. It helps in the search for new ways to fight disease, and in the study of the nervous system as well as...
