DNA constantly replicates itself by making hand-written copies of your bodys instruction manual using the chunks of bases that form the words. Codon, Nucleotide, gene . 2. These very unusual chromosomes are called 'lampbrush chromosomes' due to their resemblance to the brushes used in earlier times to clean kerosene lamps. This number, along with the visual appearance of the chromosome, is known as the karyotype,[1][2][3] and can be found by looking at the chromosomes through a microscope.
