-Almost all mutations are neutral

-Chemicals & UV radiation cause mutations

-Many mutations are repaired by enzymes]]> 2022-01-25 01:27:23 UTC https://padlet.com/umananicoole/fertuukxrdr5xhra/wish/2010087465 umananicoole https://padlet.com/umananicoole/fertuukxrdr5xhra/wish/2016883298 2022-01-27 22:23:10 UTC https://padlet.com/umananicoole/fertuukxrdr5xhra/wish/2016883298 umananicoole https://padlet.com/umananicoole/fertuukxrdr5xhra/wish/2016887563 A change in the chromosomal structure occurs involving a lot of genes.]]> 2022-01-27 22:27:42 UTC https://padlet.com/umananicoole/fertuukxrdr5xhra/wish/2016887563 umananicoole https://padlet.com/umananicoole/fertuukxrdr5xhra/wish/2016888866 five types exist]]> 2022-01-27 22:29:08 UTC https://padlet.com/umananicoole/fertuukxrdr5xhra/wish/2016888866 umananicoole https://padlet.com/umananicoole/fertuukxrdr5xhra/wish/2016890399 Brakes in chromosome produces genetic material deleted.]]> 2022-01-27 22:31:01 UTC https://padlet.com/umananicoole/fertuukxrdr5xhra/wish/2016890399 umananicoole https://padlet.com/umananicoole/fertuukxrdr5xhra/wish/2016892074 A segment of the chromosome breaks off, and it splits to to the opposite direction to finally be reinserted]]> 2022-01-27 22:33:03 UTC https://padlet.com/umananicoole/fertuukxrdr5xhra/wish/2016892074 umananicoole https://padlet.com/umananicoole/fertuukxrdr5xhra/wish/2016893112 Occurs when a section of DNA is duplicated ]]> 2022-01-27 22:34:22 UTC https://padlet.com/umananicoole/fertuukxrdr5xhra/wish/2016893112 umananicoole https://padlet.com/umananicoole/fertuukxrdr5xhra/wish/2016894644 Involves two chromosomes.
