Question | Answer |
Genome | a complete set of genetic instructions for any organism. All genomes are encoded in DNA. |
Know the different divisions of Genetics | transmission, molecular, and population genetics. |
Transmission Genetics | encompasses basic principles of heredity and how traits are passed from one generation to the next. |
Molecular Genetics | how genetic information is encoded, replicated, and expressed. It concerns the chemical nature of the gene itself. |
Population Genetics | explores the genetic composition of groups of indivuals members of the same species and how that composition changes geographically and with the passage of time. ] |
What is a model organism? | an example of echoli. The whole genetics frequency is mapped out and it makes it easy to work with. KNOW SOME EXAMPLES OF ORGANISMS!! (Their scientific name). |
Published the first description of mitosis. | Water Flemmings. |
Who was the first to propose that genes were on chromosomes? | Walter Sutton. |
The 3 dimensional structure of DNA | James Watson and Grancis Crick. |
Came up with the first way of sequencing DNA | Water Gilbert and Frederick Sanger. |
What is cell theory? And who came up with it? | All cells come from preexisting cells. Schieden and Schwann. |
Gene | a unit of information that encodes an inherited characteristic ( trait or phenotype)- what is expressed and what you can see. |
Allele | one or more alternate forms of one or more genes. |
Genotype | complete set of genetic information from an organism. Set is a single haploid bunch of genes you get from a SINGLE parent. |
Somatic sells | non sex cells. |
Germ line cells | sex cells. |
Gametes | haploid final cell form that comes from germ line cells. |
What is chromatin? | is DNA and its associated protein. |
Viruses | are not alive but they can reproduce. Can have a DNA or a RNA genome. |
pangenesis. | The theory that specific particles carry information from various parts of the body to the reproductive organs, from which they are passed to the embryo at the moment of conception |
preformationism. | Inside of the egg or sperm there exists a fully formed miniature adult which simply enlarges in the course of development |
inheritance of acquired characteristics | In which traits acquired in a person’s lifetime become incorporated into that person’s hereditary information and are passed on to offspring. |
blending inheritance. | Proposed that offspring are a blend or mixture of parental traits |
germ-plasm theory | The cells in the reproductive organs carry a complete set of genetic information that is passed to the egg and sperm |

Six genetic organisms | 1) Drosophila melanogaster, 2) Escherichia coli, 3) Caenorhabditis elegans, 4) Arabidopsis thaliana, 5) Mus musculus 6) Saccharomyces cerevisiae |
Transmission | transmiting from one generation to another |
What was the first type of bacterial gene to be sequenced? | Haemophilus influenza |
The first eukaryote sequenced? | Saccharomyces cerevisiae |
Mutation | an inheritable change of genes. |
The simplest thing in genetics is a | gene |
