Genetic recombination – the exchange of segments, typically genes, between two DNA Molecules Genome – The sum of all the genetic material in a cell or virus Genotype – actual set of genes in an organisms genome Histone – globular protein found in eukaryotic and archael chromosomes Horizontal gene transfer – process in which a donor cell contributes p-art of its genome to a Recipient cell, which may be a different species or genus from the donor Lagging strand – daughter strand of DNA synthesized in short segments rthat are later joined. Synthesis of the lagging strand always moves away from the replication fork and lags behind synthesis of the leading strand Light repair – mechanism by which prokaryotic DNA photolyase breaks the bonds between Adjoining pyrimidine nucleotides, restoring the original DNA sequence Mutagen – physical or chemical agent that introduces a mutation Nucleoid – region of the prokaryotic cytosol containing the cell’s chromosome(s) Nucleosome – bead of DNA bound to histone in a eukaryotic chromosome Operator – regulatory element in an operon where repressor protein binds to stop transscription Operon – a series of genes, a promoter, and often an operator sequence controlled by one Regulatory gene. The operon model explains gene regulation in prokaryotes Phenotype –

    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.
