Gene, A section of DNA that contains instructions to make a specific protein., Allele, Different versions of the same gene (e.g. the gene for eye color might have a blue allele and a brown allele)., DNA, A long molecule made of nucleotides that carries genetic instructions used in growth, development, functioning, and reproduction of all living things., DNA Molecule, A double-stranded, twisted ladder-shaped structure (double helix) made up of four bases (A, T, C, G). It stores the genetic code that determines traits., Base, One of the four chemicals (A, T, C, G) that make up the "rungs" of the DNA ladder., Base Pair, Two bases joined together in the DNA molecule. A pairs with T, and C pairs with G., Sugar, The deoxyribose part of the DNA backbone that connects to the phosphate group and the base., Phosphate, A chemical group that, along with sugar, forms the backbone of the DNA strand., DNA Replication, The process by which DNA makes an exact copy of itself before cell division., Chromosome, A thread-like structure made of DNA and protein that carries genes; humans have 46 chromosomes., Genotype, The combination of alleles an organism has for a particular gene (e.g. Bb, BB, or bb)., Phenotype, The physical traits or characteristics shown by the genotype (e.g. brown eyes or blue eyes)., Trait, A specific characteristic or feature of an organism (e.g. hair color, height, blood type)., Dominant Allele, An allele that will always show in the phenotype if it is present., Recessive Allele, An allele that only shows in the phenotype when two copies are present., Homozygous, Having two of the same alleles for a gene (e.g. BB or bb)., Heterozygous, Having two different alleles for a gene (e.g. Bb)., Mutation, A change in the DNA sequence that can lead to a new allele., Inheritance, The process by which genetic information is passed from parents to offspring., Punnett Square, A diagram used to predict the outcome of a genetic cross., Sex Chromosomes, Chromosomes that determine an organism's sex (X and Y in humans)., Genetic Variation, Differences in DNA between individuals, leading to different traits., Proteins, Molecules made from amino acids, built according to the instructions in genes, which carry out many of the cell’s functions., Mitosis, A type of cell division that produces two genetically identical cells used for growth and repair., Meiosis, A type of cell division that produces four non-identical sex cells, each with half the number of chromosomes., Nucleus, The part of the cell that contains DNA and controls the cell’s activities., Cells, The basic unit of life. All living organisms are made of one or more cells.
