DNA- The abbreviation DNA refers refers to a form of Nucleic Acid ( a complex organic acid found in the nucleus) known as Deoxyribonuceic Acid. It is a double-helical structure made up of two strands that run anti-parallel to each other, twisted together around a common axis. Each strand of DNA, which comprises of a polynucleotide chain held together by phosphates, is made up of a Deoxyribose sugars bonded to nitrogenous bases (guanine, adenine, thymine or cytosine) with the complementary based to that nitrogenous base on one strand being on the second strand. This structure which is held together by hydrogen bonds between the two complementary bases, contain genetic information carried by every cell and as such is responsible for directing all the activities of the cell.

Gene- A Gene, which is deemed the unit of genetic inheritance, refers to a segment of the DNA sequence that codes for amino acid peptides that interlink to for proteins (thus being that chemical instruction that allows for protein synthesis in cells). It is these proteins that carry out bodily and cellular functions, since protein plays a major role in the functioning of cells.

Chromosomes- A chromosome is a thread-like long coil of DNA located inside the nucleus of cells. Each chromosome is made up of a pair of chromatid that is joined at a center known as the centromere with each chromatid being made up of DNA coiled around proteins (often time histone). Chromosomes are passed from parent to off spring during nuclear division.

Answer from: Quest

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

Bisphenol a (often called bpa) is a chemical found in products that people use every day, from water bottles to food containers to children's toys. unfortunately, bpa leaches out of its many products and makes its way into our bodies. what are the health effects of bpa exposure? ongoing research is finding that elevated exposure to bpa can affect a wide variety of developmental and physiological processes, but one of the first studies of bpa's health effects came about because of a simple mistake in the lab. at a laboratory at case western reserve university in 1998, geneticist patricia hunt was making a routine check of her female lab mice. as she extracted and examined developing eggs from the ovaries, she began to wonder what had gone wrong. she noticed that many of the eggs showed problems with their chromosomes, and some had irregular amounts of genetic material, which can lead to miscarriages and birth defects in mammals. she learned that a lab assistant had mistakenly washed the plastic mouse cages and water bottles with a harsh soap, releasing bpa from the plastic. knowing that bpa is an endocrine disruptor, a chemical that can enter organisms and mimic hormones, hunt set out to discover whether it had adversely affected her mice.
