Gene Technology Polymerase Chain Reaction (PCR) Using PCR, minute amounts of DNA can be replicated very rapidly producing enough DNA to easily detect, study and use in a variety of applications. PCR has become an essential tool in crime investigations and diagnosing genetic diseases. Producing a Vaccine Using genetic engineering techniques, vaccines can be developed by inserting genes from disease-causing microbes into harmless bacteria or viruses. Once these modified harmless microbes are injected into the body, they stimulate the production of disease-attacking antibodies. T T C G G T A A C G G DNA Fingerprinting Each person has a unique set of DNA. Because of this uniqueness, it can be used to produce a genetic fingerprint known as DNA fingerprinting. It is a method used by scientists to solve crimes, determine familial relationships or to track hereditary diseases. 1. DNA is extracted from the cell. 2. The extracted DNA is cut into smaller pieces with special enzymes. 3. The DNA pieces are placed on a gel that uses electric current to push them through the gel and separate them according to size. The larger DNA pieces remain closer to the top, while the smaller ones move towards the bottom. 4. The separated DNA pieces on the gel are then stained to reveal their unique banded pattern known as a DNA fingerprint. gel (stained) electrophoresis system DNA added A person injected with the harmless virus containing the gene for the antigen produces antibodies against it. www.newpathlearning.com © Copyright NewPath Learning.

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. The hereditary information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C) and thymine (T). The order, or sequence, of these bases, determines the information available for building and maintaining an organism; similar to the way in which letters of the alphabet appear in a certain order to form words and sentences. DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each chromosome contains thousands of genes. A gene is a section of a DNA strand that is made up of a series of bases which contains the information for cells to make one specific protein. Proteins in cells act as messengers and help to determine the traits of an organism such as the different shapes, sizes, colors and other features found in living organisms. Copying DNA The amount of DNA doubles during the beginning of mitosis. The double stranded DNA unzips and each strand becomes a template on which a new strand is formed. Complementary bases pair-up with the exposed bases on the template strand. Every amino acid is coded by a sequence of three bases called a codon. A copy of the DNA (mRNA) is transferred from the nucleus to the cytoplasm. Translation mRNA runs through the ribosome three bases at a time; tRNA brings amino acids to the ribosome. Each amino acid is attached to the growing protein chain in proper order.

Meiosis I Meiosis II Meiosis During meiosis, a parent cell divides into four sex cells each with half the number of chromosomes as the parent cells. Sex cells of males are called sperm cells and sex cells of females are called egg cells. Anaphase I The chromosome pairs split and pull apart to opposite ends of the cell. Anaphase II The centromeres split and the single chromosomes move apart to opposite ends of the cell. Metaphase II Chromosome pairs line up in the middle of the cell. Prophase II Double-stranded chromosomes and spindle fibers reappear in each new cell. Telophase II & Cytokinesis Four sex cells are produced, each with only one chromosome from each original pair.

Mitosis Cell Growth DNA Replication Cytokinesis Preparation for Mitosis Interphase The Cell Cycle Cells reproduce by a process called cell division. The cell cycle is the sequence of stages of growth and division that a cell undergoes. The three stages of the cell cycle include interphase, mitosis, and cytokinesis. The chromatin condenses and spindle fibers form at each side of the cell. The nuclear membrane breaks apart. The spindle fiber splits the centromere and the chromatids move to opposite sides of the cell. Interphase is the first stage of the cell cycle and the period before cell division. During this phase, the cell matures, copies its DNA, and prepares to divide. daughter cells The chromosomes line up along the center of the cell and the spindle fibers attach to each chromosome at the centromere. Stages of Mitosis Interphase Anaphase Telophase & Cytokinesis Prophase Metaphase During Telophase the chromosomes loosen on each side and the nuclear membrane begins to form around the chromatin (strands of DNA). During Cytokinesis the cell membrane pinches in at the middle of the cell dividing the cell into two separate daughter cells. Each daughter cell gets half of the cell organelles and an identical set of chromosomes. Plant Cell Division plate forming www.newpathlearning.com © Copyright NewPath Learning.

Endoplasmic reticulum is a transport system of tubes and channels connecting organelles in the cell. Nucleus is the control center of the cell. It houses the nucleolus and the genetic material (chromatin). Nuclear envelope is a membrane which surrounds and protects the nucleus. Nucleolus is the site where ribosomes are made. Chromatin contains the genetic material that is used for directing the cell functions. Nuclear pores allow materials to pass in and out of the nucleus. Ribosomes are the factories that produce proteins needed by the cell. Cytoplasm is a gel-like substance containing the organelles. Lysosome contains chemicals (enzymes) that break down and recycle harmful materials. Mitochondrion is a rod-like structure that converts the energy in food molecules to a form that the cell can use. Golgi bodies are organelles that direct different materials made in the cell where they need to go. Cell wall is a rigid outer layer of plant cells that provides support. Vacuoles are sacs that contain water and store nutrients and waste products. Microfilaments (cytoskeleton) Centrioles Chloroplasts contain chlorophyll which captures energy from the Sun and uses it to produce food for the plant in a process known as photosynthesis.

Scientists examine a karyotype to identify and evaluate the size, shape and number of chromosomes in a human cell. Extra, missing or abnormal positions of chromosome pieces can cause problems with a person's growth, development and body functions. A normal human male karyotype is represented as 46, XY and a normal female karyotype is represented as 46, XX.

All Rights Reserved. 94-4635 Genes and Heredity Heredity Heredity is the passing of traits or characteristics from one generation to the next. When an egg and a sperm unite, a copy of each parent’s genes is incorporated into the resulting embryo. Humans have about 100,000 genes spread over 46 chromosomes. Half of these chromosomes come from the person’s mother, and the other half come from the person’s father. A Look at Traits The laws of dominance determine whether a child will display the trait coded for by a gene inherited from its father or its mother. Some genes, called dominant genes, express themselves when only one copy is present. Other genes, called recessive genes, express themselves only when two copies are present. Scientists use capital letters to designate dominant genes and lowercase letters to represent recessive ones. An individual with two recessive genes or two dominant genes for a trait is said to be homozygous for that trait. An individual with one dominant gene and one recessive gene is said to be heterozygous. Making a Pedigree A pedigree is a diagram showing the transmission of a genetic trait through several generations of a family. It provides clues to the kinds of traits that may be passed on to future offspring. A pedigree is also useful for determining the genotype of an individual, as well as predicting the genotypes of future generations. In a pedigree, each individual is represented by an Arabic number, while each generation is represented by a Roman numeral. Squares represent males and circles represent females. A shaded box indicates an individual who displays the characteristic being studied. The genetic makeup of an individual is known as a genotype, while the observable physical characteristics that result from an individual’s genotype is known as a phenotype.
