RNA:single stranded nucleic acid that contains the sugar ribose
Messenger RNA: type of RNA that carries copies of instructions for the assembly of amino acids into proteins from DNA to the rest of the cell
Ribosomal RNA: type of RNA that combines with proteins to form ribosomes
Transfer RNA: type of RNA that carries each amino acid to a ribosome during protein synthesis
Transcription: synthesis of an RNA molecule from a DNA template
RNA polymerase: enzyme that links together the growing chain of RNA nucleotides during transcription using a DNA strand as a template
Promoter: specific region of a gene where RNA polymerase can bind and begin transcription
Intron: sequence of DNA that interrupts a gene-coding sequence or nontranslated sequence, the corresponding segment being removed from the RNA copy before transcription
Exon: any nucleotide sequence encoded by a gene that remains present within the final mature RNA product of that gene after introns have been removed by TNA splicing
Polypeptide: short polymers of amino acid monomers linked by peptide bonds formed between two molecules when the carboxyl group of the other molecule.
Genetic code: set of rules by which information encoded within genetic material is translated into proteins by living cells
Codon: A group of three nucleotide bases in mRNA that specify a particular amino acid to be incorporated into a proteins
Translation: process by which the sequence of bases of an mRNA is converted into the sequence of amino acids of a protein
Anticodon: group of three bases on a tRNA molecule that are complementary to the three bases of a codon of mRNA
Gene expression: Process by which a gene produces its product and the product carries out its function
Mutation: change in the genetic material of a cell
Point mutation: gene mutation in which a single base pair in DNA has been changed
Frameshift mutation: mutation that shifts the “reading frame” of the genetic message by inserting or deleting a nucleotide
Mutagen: chemical or physical agents in the enviorment that interact with DNA and may cause a mutation
Polyploidy: condition in which an organism has extra sets of chromosomes
Operon: in prokaryotes, a group of adjacent genes that share a common operator and promoter and are transcribed into a single mRNA
Operator: short DNA region, adjacent to the promoter of a prokaryotic operon, that binds repressor proteins responsible for controlling the rate of transcription of the operon
RNA interference: introduction of double stranded RNA into a cell to inhibit gene expression
Differentiation: process in which cells become specialized in structure and functions
Homeotic gene: a class of regulatory genes that determine the identity of body parts and regions in an animal embryo, Mutations in these genes transform one body part into another
Homebox gene: the homebox is a DNA sequence of approximately 130 base pairs, found in many homeotic genes that regulate development. Genes containing this sequence are known as homeobox genes, and they also regulate the expression of other genes
Hox gene: a group of homeotic genes clustered together that determine the head to tail identity of body parts in animals
