Dna the chromosomal molecule that transfers genetic characteristics by way of coded instructions for the structure of proteins. Genome the full set of genes in ach cell of an organism. Genotype: specific genetic makeup, present from conception, never change. Phenotype: observable characteristics produced by the genetic endowment, can be altered by other genes or the environment (usually due to ingestion ex. People who are genetically supposed to become tall but live in an environment that stunts their growth (such as getting rickets) and so they never grow to the height they should have (the phenotype affecting the genotype) A chromosome is a tightly coiled molecule of dna that contains many genes. Genes contain the genetic blueprint for you.
