1. anticodon: the group of three bases on a tRNA molecule that are complementary to an mRNA codon 2. bacteriophage: the one virus that infects only bacteria 3. base pairing: this is the principle that bonds in DNA can form only between adenine and thymine and between guanine and cytosine in pairs 4. chromatin: the granular material visible within the nucleus; consists of DNA tightly coiled around proteins in the body 5. codon: three-nucleotide sequence on messenger RNA that codes for a single amino acid only 6. differentiation: the process in which molecule tend to move from an area where they are more concentrated to an area where they are less concentrated 7. DNA polymerase: enzyme involved in DNA replication that joins indicidual nucleotides to produce a DNA molecule 8. exon: expressed sequence of DNA ; codes for a protein 9.

Unformatted text preview: frameshift mutation: mutation that shifts the "reading" frame of the genetic message by inserting or deleting a nucleotide 10. gene: sequence of DNA that codes for a protein and thus determines a trait 11. histone: protein molecule around which DNA is tightly coiled in chromatin 12. hox gene: series of genes that controls the differentiation of cells and tissues in an embryo 13. intron: sequence og DNA that is not involved in coding for a protein 14. messenger RNA (mRNA): RNA molecule that carries copies of instructions for the assembly of amino acids into proteins from DNA to the rest of the cell 15. mutation: change in a DNA sequence that affects genetic information 16. nucleotide: monomer of nucleic acids made up of a 5-carbon sugar, a phosphate group, and a nitrogenous base...
