| heredity | passing of physical characteristics from parents to offspring |
| trait | for of a characteristic such as stem, height , or seed color |
| genetics | scientific study of heredity |
| probability | number that describes how likely an event will occur |
| punnett square | chart that shows all possible combinations of alleales that can result from a genetic cross |
| phenotype | organisms genetic make up or allele combination |
| codominance | an inheritance pattern for some alleles |
| codominance - genes | neither dominant or recessive genes |
| cell cycle | regular sequence of growth and division that cells undergo |
| interphase | the first stage of cell division |
| during the interphase | cells grow and makes a copy of its DNA and prepares to divide into 2 cells |
| replicate | next phase the cell makes an exact copy of its DNA in its nucleus making |
| mitosis | the second stage of division when the cell split apart. |
| during mitosis | one copy of the DNA is distributed into each of the 2daughter cells |
| chromosomes | thread-like chromaticn in the nucleus compact double rod structures |
| miosis | reduces chromosomes by half |
| crossing over | DNA exchange between homolygus chromosomes |
| independent assortment | random line up for division |
| first meiotic division | separation of homolygus chromosomes |
| second meiotic division | separation of sister chromatads |
| genetic code | main function of genes is to control the production, proteins in an organism cell |
| protein | building blocks of cells |
| tRNA | carries amino acid to the ribosome and adds them to the growing protein chain |
| mRNA | copies the code message from the DNA in the nucleus and carries the message to the ribosomes |
| polymer | more complex things made of monomers (amino acids) |
| receptors | act as keyholes to your cell |
| antibodies | protect cell from invasion |
| enzymes | speed up reactions |
| gene | section of DNA that codes for its instructions for proteins- |
| genes control what ? | instructions of proteins control all your traits |
| protein | a bunch of amimo acids make protein |
| DNA has ____ strands | 2 |
| RNA has ___ strands | 1 |
| RNA contains | different sugar |
| RNA and DNA contain | nitrogen bases |
| mRNA does what? | carries the coded message from DNA in the nucleus and carries the message into cytoplasm |
| ribosome code | determines YOU |
