Even supposing we regularly seek social and ancient files for clues to our previous, organic records maybe carry crucial proof of our history. The features we inherit from our mom and dad and move directly to our offspring are encoded in our genes and DNA and show a lot approximately either our origins and our destiny. This quantity examines the attention-grabbing biology at the back of genetics and genetic issues. It additionally rigorously considers the foundations of gene manipulation and genetic engineering whose power to revolutionize drugs, undefined, and agriculture is turning into more and more obtrusive with each new discovery.

Sample text

The term genetic engineering initially encompassed all of the methods used for DNA contains two strands of nucleotides linked together by chemical bonds. Each nucleotide contains a phosphate, deoxyribose (a sugar), and one of four nitrogen-containing bases: adenine (A), guanine (G), cytosine (C), or thymine (T). The bases of one strand are linked to bases of the second strand. Because of their structures, adenine can only pair with thymine, and cytosine can only pair with guanine. Encyclopædia Britannica, Inc.

Morgan also confirmed the findings of earlier studies showing that genes lying close together on the same chromosome tend to be inherited together. Chromosomes and Cell Division Chromosomes are aggregates of DNA and protein found in every living thing. Every gene has a specific location on a particular chromosome. Most organisms have two sets of paired chromosomes (the diploid number), with one set (the haploid number) inherited from each parent. Each chromosome pair consists of two homologs—chromosomes that resemble each other in both appearance and genetic characteristics—and each homolog has one allele of each gene pair.

Polyploidy is found in some animals, including goldfish and some salamanders, and most commonly in plants, including ferns, wheat, pansies, and many others. Humans are diploid; each somatic cell has a set of 23 chromosomes from each parent, for a total of 46. In humans, the haploid number (n) is 23, and the diploid number (2n) is 46. “Mitosis is the process in which one cell divides into two identical cells. ” Jupiterimages/Photos. com/Thinkstock 36 The Nature of Chromosomes and Genes Mitosis Unicellular organisms such as bacteria and the somatic cells of higher organisms replicate through mitosis, a process in which one cell gives rise to two genetically identical daughter cells.
