BIOL 3040 Study Guide - Retrovirus, Exon, Haplotype
Document Summary
List the major groups of living organisms in approximate order of genome size from smallest to largest: viruses, archaea, bacteria, fungi, birds, teleost fishes, molluscs, reptiles, mammals, frogs, insects, cartilaginous fishes, green algae, protozoa, salamanders, lungfishes, flowering plants. Excise the original dna element and reinsert it at another site and the transposon jumps to a new location but the old copy is lost: nonconservative transposons. Leaves the original copy intact and creates a new copy elsewhere: line-1 elements. Long interspersed elements most common in human genome and known as retrotransposons. They are called autonomous transposons because they encode the enzymes necessary to catalyze their own movement within the genome. Might be remnants of retroviral insertions into the genome but has lost ability to make a viral particle: sines. Short interspersed elements are nonautonomous transposons because they lack the capacity for independent replication example: alu elements: explain what it means when it is said that transposons are selfish genetic elements.
