Science of heredity
|
Chromosome
|
Structue that contains cell DNA
|
Gene
|
-segment of DNA; codes for specific product
-related genes scattered throughout chromosome
(eukaryotes only)
-related genes grouped in operons w/ single
promoter (prokaryotes only)
|
Genotype
|
Genetic make-up of cell; (potential properties)
|
Phenotype
|
Genes that are expressed by cell
-used to make proteins that give cell its characteristics
-environmental conditions play role (effect whatever phenotype will be inhibited)
|
Genome
|
-one conplete copy of that cells genes
-chromosome + plasmids
|
DNA
|
Carries info on how cells will build proteins
|
Enzymes
|
Used to make all other biomolecules
|
Structural proteins
|
-for structures in cell
-proteins give the cell its characteristics (phenotypes)
|
Bacterial chromosome
|
-circular piece of double stranded DNA
-loosely packed
-attach to membrane
-contain many genes
|
