words only definitions & notes
  1. organelle
    a specialized part of a cell; analogous to an organ
    Organelle DNA

    Not all genetic information is found in nuclear DNA.
  2. eukaryote
    an organism of one or more cells with membrane-bound nuclei
    The location and base sequence of each promoter site vary for prokaryotes (bacteria) and eukaryotes (higher organisms), but they are both recognized by RNA polymerase, which can then grab hold of the sequence and drive the production of an mRNA.
  3. mRNA
    the template for protein synthesis
    Ribonucleic Acids
    In addition to mRNA, DNA codes for other forms of RNA, including ribosomal RNAs (rRNAs), transfer RNAs (tRNAs), and small nuclear RNAs (snRNAs). rRNAs and tRNAs participate in protein assembly whereas snRNAs aid in a process called splicing -the process of editing of mRNA before it can be used as a template for protein synthesis.
  4. allelic
    of or relating to alleles
    Determining the allelic condition used to be accomplished solely through the analysis of pedigrees, much the way Mendel carried out his experiments on peas.
  5. phenotype
    observable characteristics produced by genes and environment
    When two individuals display different phenotypes of the same trait, they are said to have two different alleles for the same gene.
  6. ribosome
    a particle in a cell that helps synthesize proteins
    Because mitochondria have their own DNA, RNA, and ribosomes, this scenario is quite possible.
  7. phenotypic
    of or relating to or constituting a phenotype
    These expressed, or phenotypic, traits are attributable to genotypic variation in a person's DNA sequence.
