DNA Grimes
What all makes us - us? Use this stack to help you better help understand DNA!
| Definition | |
|---|---|
| What are the 4 nitrogen bases that make up the "rungs" of our DNA? | Adenine, Thymine, Guanine, and Cytosine |
| What nitrogen bases will always be grouped together in our DNA, no matter what? | Adenine will always be grouped with Thymine, and Guanine will always be grouped with Cytosine. |
| When a strand of DNA is coiled tightly, what is it called? | Chromosome |
| Gene | A segment of DNA that contains info to build proteins AND you! |
| Phosphate | A mineral compound that makes your DNA |
| Genotype | Your genetic makeup - what makes you, you! |
| DNA stands for... | Deoxyribonucleic Acid |
| Here is an example of half a DNA strand, figure out the matching half using the chain here: ATTAGCGGCATTA | TAATCGCCGTAAT |
| Phenotype | OBSERVABLE characteristics or traits in an organism |
| Alleles | one of two or more versions of a gene |
| Where is DNA located? | In the nucleus of the cell |
| What are the 3 parts that make up a nucleotide? | Phosphate, sugar, and a base |
| Homozygous | 2 SAME alleles in a gene |
| Heredity | Passing of traits from parents to offspring |
| Trait | Genetic characteristics |
| Genetics | Study of heredity |
| Dominant Allele | Strong form of a gene that is normally seen |
| Recessive Allele | Weak form of a gene that is normally covered up |
| Heterozygous | 2 DIFFERENT alleles in a gene |
| Hybrid | Offspring of different species or varieties |
| Variation | Different form or version of something |
| Punnett Square | Tool used to predict possible genes for offspring between two parents |
| Mutation | Permanent change in the DNA sequence of an organism |
| Chromosome | Found in the nucleus, carries genetic info in the form of genes |
| DNA | Self-replicating material that carries genetic info |
| What is the shape of DNA? | Twisted ladder |
| What is the shape of chromosomes? | An X |
| How many pairs of chromosomes do humans cells have? | 23 pairs |
| An example of a dominant gene is if your mother is black, and your father is white, you would inherit your mother's dominant genes and have a darker skin tone than you would from your father. | An example of a recessive gene is if all of your family has brown hair, and you are the only one with red hair, both of your parents had that red hair gene, but it wasn't strong enough to dominate the brown hair gene. You beat the odds! |
| Example of phenotypes | Hair color, eye color, and skin color |
