Genetics chp 1

QuestionAnswer
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
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 pangenesis.
In which traits acquired in a person’s lifetime become incorporated into that person’s hereditary information and are passed on to offspring. inheritance of acquired characteristics
Inside of the egg or sperm there exists a fully formed miniature adult which simply enlarges in the course of development. preformationism.
Proposed that offspring are a blend or mixture of parental traits blending inheritance.
The cells in the reproductive organs carry a complete set of genetic information that is passed to the egg and sperm germ-plasm theory
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
