8. Orthologous Genes: A type of homologous gene (genes that arise from a common DNA ancestral sequence), this gene diverged after a speciation even 9. Paralogous Genes: Diverged from one another within a species Chapter 10 1. DNA Polymorphism: any difference in the nucleotide sequence between individuals. These differences can be single base pair changes, deletions, insertions, or even changes in the number of copies of a given DNA sequence. 2. SNP: Single nucleotide polymorphism is the most common type of DNA Polymorphism in humans. a DNA sequence variation occurring when a single nucleotide adenine (A), thymine (T), cytosine (C), or guanine (G]) in the genome (or other shared sequence) differs between members of a species or paired chromosomes in an individual 3. DNA Fingerprinting: DNA fingerprinting or DNA profiling is a process used to determine the nucleotide sequence at a specific part of the DNA that is unique in all human beings. 4. SSR: Simple sequence repeats. sometimes described as genetic 'stutters,' are DNA tracts in which a short base-pair motif is repeated several to many times in tandem (e.g. CAGCAGCAG). These sequences experience frequent mutations that alter the number of repeats 5. Locus: in genetics is a fixed position on a chromosome, like the position of a gene or a marker (genetic marker). Each chromosome carries many genes; human's estimated 'haploid' protein coding genes are 19,000–20,000, on the 23 different chromosomes 6. Exome: a genomic technique for sequencing all of the protein-coding region of genes in a genome (known as the exome). It consists of two steps: the first step is to select only the subset of DNA that encodes proteins Chapter 11 1. Chromosome: a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes 2. Euchromatin: chromosome material which does not stain strongly except during cell division. It represents the major genes and is involved in transcription 3. Nucleosome: a structural unit of a eukaryotic chromosome, consisting of a length of DNA coiled around a core of histones 4. FISH: Fluorescence in situ hybridization (FISH) provides researchers with a way to visualize and map the genetic material in an individual's cells, including specific genes or portions of genes. This may be used for understanding a variety of chromosomal abnormalities and other genetic mutations 5. Chromatin: a macromolecule made up of DNA or RNA and proteins. ... Its functions are to package DNA into a smaller volume to fit in the cell, strengthen the DNA to allow mitosis and meiosis, and to serve as a mechanism to control expression. The chromatin is found within the cell nucleus of eukaryotic cells 6. Histones: highly alkaline proteins found in eukaryotic cell nuclei that package and order the DNA into structural units called nucleosomes. They are the chief protein components of chromatin, acting as spools around which DNA winds, and playing a role in gene regulation 7. Telomere: They function to protect the ends of chromosomes from sticking to each other.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
