A study of biology includes the study of the chemical basis of living organisms, DNA.

Other related sciences include microbiology and organic chemistry. The word science comes from a Latin word scientica, which means knowledge, or information.

Science is a process of systematically gathering detailed information and gaining exact knowledge. We do not know all the "life" information secrets but we are learning more every day. The three biological life cycle s, are; Zygotic meiosis, Sporic meiosis, and Gametic meiosis, Amoeba - one basic life form.

The science of evolution

Amoebas and there are many different kinds feed by phagocytosis the engulfing and ingesting of foreign particles or waste matter by phagocytes --they flow around their prey usually a smaller cell and engulf it.

Organism that eat other organisms are usually called "consumers".

The amoeba's cell membrane then fuses with itself, trapping the prey in a "food vacuole" where it will be digested. In the first place, no slight inconvenience results from too great separation beween branches of study which serve for the perfection of one art.Ian K.

He has created two national health initiatives—the 50 Million Pound Challenge and the Makeover Mile—and has served two terms on the President’s Council on Fitness, Sports, and Nutrition.

Featured Advancing Products and Practices to Fight Climate Change. In December , Monsanto announced a first-of-its-kind program to introduce a model for carbon neutral crop production that will help reduce the carbon footprint of crop production. Andrew Ellington is the Fraser Professor of Biochemistry at the University of Texas at Austin.

He is perhaps best known for the invention of the word "aptamer," but is now most involved in the development and evolution of artificial life, including nucleic acid operating .

The effect of base substitutions, or point mutations, on the messenger-RNA codon AUA, which codes for the amino acid isoleucine. Substitutions (red letters) at the first, second, or third position in the codon can result in nine new codons corresponding to six different amino acids in addition to isoleucine itself.

However, some intrinsic characteristics of IMCRs hamper this approach. Both reactions can proceed spontaneously under appropriate conditions, and these competing background reactions can have an impact on the enantiomeric excess.

The activation responsible for the enantioselectivity must occur on the carbonyl (Passerini reaction) . DNA cloning Cloning is the process of moving a gene from the chromosome it occurs in naturally on the topology of the DNA molecule. Covalently closed supercoiled molecules bind less ethidium bromide than linear DNA because the DNA is constrained.

Linear molecules, The complex is responsible for both restriction and modification.
