Evolution describes the changes in the gene pool of a species over time. These changes are the results of mutations, natural selection and genetic drift. Often populations produce more offspring than the environment can support; in other words, they often exceed the carrying capacity. Over-production of offspring leads to intraspecific competition and survival of the…
Genetics Definitions Genes: portion of the DNA molecule that codes for a particular protein. Loci: location in the DNA molecule of the gene Alleles: forms of a gene Homozygous: paired alleles are identical Heterozygous: paired alleles are different Genotype: set of all alleles (i.e. genetic expression) Phenotype: all observable traits (i.e. physical expression) Genome: The…

All neutral atoms have electrons moving in orbits. Some atoms (Iron, Nickel, and Cobalt) have an electron arrangement that act like tiny…

A nucleotide consists of 3 molecules: a 5-carbon sugar (pentose) either deoxyribose (in DNA) or ribose (in RNA) a phosphate attached at the #5 carbon of the sugar an organic or nitrogenous base – a nitrogen containing ring structure – attached at the #1 carbon of…
In chemistry, isomers are compounds with the same molecular formula but different structural formulas. The word is derived from the Greek ισομερης, isomerès; isos = “equal”, méros = “part”. There are many different classes of isomers, like stereoisomers, enantiomers, geometrical isomers (see chart below). Isomers do not necessarily share similar properties, unless they also have…
Water is a unique substance essential to life. It is the most abundant molecule in any cell. Human body is 55-78% composed of water. 1. Polar Molecule – A polar covalent bond is formed between the oxygen and hydrogen. The oxygen atom is slightly negative and the hydrogen is slightly positive due to unequal sharing…
