Traits and Reproduction
Question | Answer |
---|---|
Allele | A specific form of a gene that provides instructions for making a particular protein molecule. |
Chromosome | A long piece of DNA found in the nucleus that contains many genes. |
DNA | A type of molecule that genes and chromosomes are made of. Is shaped like a spiral staircase called a double helix. |
Feature | A characteristic that all members of a species have. Ex. Silk Flexibility or Venom in Darwin's Bark Spiders. |
Fertilization | When a male and a female reproductive cell combine to create an offspring. |
Function | How something works. |
Gene | An instruction for making a protein molecule. |
Gene Version | A specific form of a gene that provides instructions for making a particular protein molecule. |
Heterozygous | Having gene versions that are different. |
Homozygous | Having gene versions that are the same. |
Inherit | To receive genes from a parent. |
Mutation | A random change to a gene that sometimes results in a new trait. |
Nonfunctional Protein | A protein molecule that does not perform its function, often because it does not connect to other molecules. |
Nucleus | The part of a cell where genes are found. |
Offspring | An organism produced as a result of reproduction. |
Protein Molecule | A type of large molecule that performs important functions inside organisms. |
Ribosomes | The parts of the cell that build protein molecules based on instructions from genes. |
Sexual Reproduction | The process in which two parents pass on their genes to create offspring. |
Structure | The way something is shaped or constructed. |
Trait | A specific characteristic of an individual organism. |
Variation | Any difference in traits between individual organisms. |
Evidence | Information about the natural world that is used to support or go against (refute) a claim. |
