    Study Notes

    Glowing Jellies

    • Jellies glow as a defense mechanism against predators, either startling or confusing them, or attracting larger predators that might scare away smaller ones
    • Glowing is an adaptive trait helping jellies survive in their environment
    • In 1992, scientists discovered a protein causing the glow, named Green Fluorescent Protein (GFP)
    • GFP is produced by the cells when a specific gene, which is a set of instructions for making a protein, is present
    • The jelly receives one copy of each gene from each parent during reproduction
    • Chromosomes come in pairs, with each pair containing one copy of a gene on each chromosome
    • Offspring inherit one copy of each chromosome from each parent, thus receiving one copy of each gene
    • If a jelly has the GFP gene, it produces GFP protein that causes the glow in the dark
    • GFP protein causes some jellies to glow in the dark
