Genetics And Ecology Flashcards
Pathogens
Disease causing agents such as bacteria and viruses
Bacteria
Single celled organisms responsible for things such as strep throat, staph infection, pneumonia. Treated with antibodies
Viruses
Replicate in the host’s cells. Common cold, flu, AIDS, herpes. Can’t be treated with antibodies
Gametes
Reproductive cells. Haploids, half as many cells as normal cells (diploids).
Meiosis
Gametes are created
DNA
Genetic code, combination of nucleotides. Shape of double helix
Gene
Unit of inheritance contained within an individual’s DNA
Alleles
Varieties of genes, two in each gene from each parents. Same are homozygous, different are heterozygous
Genotype
Genetic makeup including dominant and recessive genes
Phenotype
How genes are expressed in physical characteristics
Prokaryotic
No nucleus
Nucleus
Contains genetic material of cell
Cytoplasm
Outside nucleus, surrounds other cell structures
Ribosomes
Produce proteins
Endoplasmic reticulum
Synthesis of proteins and fats
