Document Summary
Nucleoid: in prokaryotes that contains genetic material. Nucleus: holds hereditary i(cid:374)fo (cid:894)dna(cid:895), (cid:272)o(cid:374)trols (cid:272)ell"s gro(cid:449)th & reprodu(cid:272)tio(cid:374)s. Chromosomes: threadlike structure of nucleic acids & proteins found in nucleus. Carry genitive info in the form of genes. One complete dna molecule with its associated proteins. Membrane: lipid bilayer, that acts as a selectively permeable barrier within living things. Cytoskeleton: microscopic network of protein filaments & tubules in cytoplasm of living cells, giving them shape & consistency. Compare & contrast hypothesis vs theory when used in a scientific context. Theory: a tested, well-sustained, unifying explanations for a set of verified, proven factors. Life is related & has descended from a common ancestor. Complex creature has evolved from more simple ancestors. Random mutations occur within an organism genetic code. Beneficial mutations are preserved b/c aid in survival- natural selection. Accumulations of beneficial mutations result in a new specie.
