genetics & heredity
| Question | Answer |
|---|---|
| allele | various forms of a gene, like R or r |
| amino acids | the "building blocks" that get joined together by the ribosome to make a protein |
| chromosome | the physical structure in a cell's nucleus that contains genes |
| DNA | Directions for making proteins. |
| dominant | the allele that “wins”, like R |
| Eukaryotic cell | A cell with a nucleus. |
| gene | a unit of inheritance; it is the directions for making a protein |
| genotype | the gene pair an organism has, like Rr |
| Golgi body | The organelle that folds proteins into a shape that actually works. |
| messenger RNA | it carries the protein making instructions from the DNA in the nucleus to the ribosomes in the cytoplasm. |
| mutation | a change in an organism's DNA |
| nucleotide base | a letter in the DNA "alphabet" used to create the genetic code |
| Nucleus | Holds the genetic material (DNA). |
| Organelle | A part of a cell that does a specific job. |
| phenotype | how an organism looks, like red flowers |
| protein | a molecule that does a job that helps keep an organism alive |
| Punnett Square | a chart used to show all the ways alleles from two parents can combine and be passed to offspring |
| recessive | the allele that “loses”, like r |
| replication | the process by which DNA makes a copy of itself before the cell divides |
| Ribosome | The organelle that helps make proteins by joining amino acids together. |
| transcription | the process of mRNA carrying the message from the DNA in the nucleus to the ribosomes in the cytoplasm |
| transfer RNA | it moves amino acids so the ribosome can join them together to make a protein |
| translation | the process of transfer RNA working with the ribosome to assemble amino acids into a protein |
| XX | The chromosome pair for a female |
| XY | The chromosome pair for a male |
