Document Summary
Genes: sequences of dna that might encode proteins; it can also make noncoding rna. Chromosomes: organelles that pack, store, duplicate and express dna. Genome: all chromosomes from all cells in an organism. Forward genetics: investigating the gene in the presence. Reverse genetics: investigating the function of gene by its absence. Nonhereditary traits: traits that come from environmental factors, not genes. Monohybrids individuals with 2 different alleles for a single trait. Knockout take out the whole gene. Their 3-d structure is determined by the amino acid sequence. Complementary base paring: dna is composed of nitrogenous bases that bind like this a=t; c g. We can only read dna in one direction (we read template strand 3; mrna is form in the 5) The main reason why evolution decided to make dna is because it is more stable. All living organisms use essentially the same genetic code. A gene from one organism can functionally replace a gene from another organism.
