absolute value
'Absolute Value' is used for mentioning a number regardless of it's sign. A result of a calculation may be positive or negative can be called as 'absolute value'. Any negative value needs to be converted to a positive number for additional calculation. The value itself called as 'Absolute Value'.

Genetics
Genetics
Genetics from Ancient genetikos, “genitive” and that fenesis, “origin”, a discipline of biology, is the science of heredity and variation in living organisms. The fact that living things inherit traits from their parents has been used since prehistoric times to improve crop plants and animals through selective breeding. However, the modern science of genetics, which seeks to understand the process of inheritance, only began with the work of Gregor Mendel in the midnineteenth century. Although he did not know the physical basis for heredity, Mendel observed that organisms inherit traits in a discrete manner—these basic units of inheritance are now called genes.DNA, the molecular basis for inheritance. Each strand of DNA is a chain of nucleotides, matching each other in the center to form what look like rungs on a twisted ladder.DNA, the molecular basis for inheritance. Each strand of DNA is a chain of nucleotides, matching each other in the center to form what look like rungs on a twisted ladder.enes correspond to regions within DNA, a molecule composed of a chain of four different types of nucleotides—the sequence of these nucleotides is the genetic information organisms inherit. DNA naturally occurs in a double stranded form, with nucleotides on each strand complementary to each other. Each strand can act as a template for creating a new partner strand—this is the physical method for making copies of genes that can be inherited.The sequence of nucleotides in a gene is translated by cells to produce a chain of amino acids, creating proteins—the order of amino acids in a protein corresponds to the order of nucleotides in the gene. This is known as the genetic code. The amino acids in a protein determine how it folds into a threedimensional shape this structure is, in turn, responsible for the proteins function. Proteins carry out almost all the functions needed for cells to live. A change to the DNA in a gene can change a proteins amino acids, changing its shape and function this can have a dramatic effect in the cell and on the organism as a whole.Although genetics plays a large role in the appearance and behavior of organisms, it is the combination of genetics with what an organism experiences that determines the ultimate outcome. For example, while genes play a role in determining a persons height, the nutrition and health that person experiences in childhood also have a large effect.
