Mr Camp - Topic 3

TermDefinition
asexual reproduction involves one parent, offspring is a CLONE of the parent, NO GENETIC VARIATION therefore decreases the chances of survival of the individual and the species
bond chemical link that holds molecules together, when broken, energy is released, when formed, energy is stored
chromosome threadlike structure that contains DNA, found in the nucleus
clone organism that is genetically identical to the organism from which it was produced
DNA material found in all organisms, contains genetic information about the organism, provides instructions for the building of proteins
egg gamete (sex cell) of a female, produced in the ovaries, involved in sexual reproduction, contains half the complete set of genetic information, haploid (monoploid) (n)
expressed when a gene is "turned on" the trait is seen
genes segment of DNA, contains instructions for a specific trait
genetic engineering when gene(s) is(are) inserted into the complete set of DNA of another organism EX: Human gene for insulin/growth hormone and bacterial DNA
genetics recombination formation of a new combination of genes during sexual reproduction
heredity passing of traits from parent to offspring
mutation an alteration to the DNA sequence. May have a positive, negative or no effect on the organism
replicate to copy
selective breeding process of choosing organisms with desirable traits to serve as the parents of the next generation. EX: dog breeding and race horses
sexual reprodcution two parents are involved, offspring has genetic variation, increases chances of survival of the individual and the species
sperm gamete (sex cells) of a male, produced in the testes, involved in sexual reproduction, motile, carries half of the complete set of DNA, monoploid (haploid) (n)
nucleotide section of DNA that contains a sugar, phosphate and nitrogeneous base
template pattern for a new molecule. EX: one strand of DNA during DNA replication
trait characteristic that is passed from parent to offspring through genes
