8692771653 | Mutation | a change in the genetic material of a cell; cause by a mistake during DNA replication. | ![]() | 0 |
8692771654 | Gene Mutations | changes to a single gene. | ![]() | 1 |
8692771655 | Point Mutation | involve changes in one or a few nucleotides/bases. | ![]() | 2 |
8692771656 | Substitution Mutation | one base is changed to a different base (May or may not affect the amino acid due to redundancy in the genetic code). | ![]() | 3 |
8692771657 | Insertion | adds a new base to the DNA sequence | ![]() | 4 |
8692771658 | Deletion | removes a base from the DNA sequence | ![]() | 5 |
8692771659 | Frameshift Mutation | caused by insertions and deletions that changes the reading sequence. Usually causes a significant change in the amino acid sequence. | ![]() | 6 |
8692771660 | Chromosomal mutation | change in the number or structure of a chromosome. Change the location of genes on a chromosome Change the number of copies of genes. | ![]() | 7 |
8692771661 | What are the four chromosomal mutations? | Deletion Duplication Inversion Translocation | ![]() | 8 |
8692771662 | Duplication | extra copy of all or part of a chromosome | ![]() | 9 |
8692771663 | Inversion | part of a chromosome switches direction. | ![]() | 10 |
8692771664 | Translocation | part of one chromosome breaks off and attaches to another chromosome. | ![]() | 11 |
8692771666 | Chromosomal Disorders | entire chromosomes, or large segments of them are missing or duplicated. | ![]() | 12 |
8692771667 | Nondisjunction | chromosomes do not separate during meiosis; extra or missing chromosomes. | ![]() | 13 |
8692771668 | Reciprocal Translocation | part of a chromosome breaks off an attaches to another chromosome, but in this case it is equal amounts between homologous chromosomes. AKA Crossing over- totally normal | 14 | |
8692771669 | Silent mutation | mutations in DNA that do not significantly alter the phenotype of the organism in which they occur | ![]() | 15 |
8692771670 | trisomy | there are three copies of a particular chromosome, instead of the normal two | ![]() | 16 |
8692771671 | monosomy | the condition of having a diploid chromosome complement in which one (usually the X) chromosome lacks its homologous partner. | ![]() | 17 |
8692771674 | Karyotype | the number and visual appearance of the chromosomes in the cell nuclei of an organism or species. | ![]() | 18 |
8692771676 | Mutagen | an agent, such as radiation or a chemical substance, that causes genetic mutation. | ![]() | 19 |
