It contains the code for building proteins]]> 2017-01-30 13:26:33 UTC https://padlet.com/farnerc1/d97wxg2ewi27/wish/150210089 farnerc1 https://padlet.com/farnerc1/d97wxg2ewi27/wish/150210483 2017-01-30 13:28:13 UTC https://padlet.com/farnerc1/d97wxg2ewi27/wish/150210483 farnerc1 https://padlet.com/farnerc1/d97wxg2ewi27/wish/150210584 DNA is shaped like a twisted ladder. It's called a double helix. This shape allows DNA to coil up it's 6 foot length and fit in a nucleus]]> 2017-01-30 13:28:42 UTC https://padlet.com/farnerc1/d97wxg2ewi27/wish/150210584 farnerc1 https://padlet.com/farnerc1/d97wxg2ewi27/wish/150211096 2017-01-30 13:30:33 UTC https://padlet.com/farnerc1/d97wxg2ewi27/wish/150211096 farnerc1 https://padlet.com/farnerc1/d97wxg2ewi27/wish/150211217 DNA's code is made up of 4 bases or "letters" . These letters always pair in the same way: A-T, C-G. They form 3 letter "words" which make "sentences" called genes. Genes are instructions to build proteins]]> 2017-01-30 13:31:00 UTC https://padlet.com/farnerc1/d97wxg2ewi27/wish/150211217 farnerc1 https://padlet.com/farnerc1/d97wxg2ewi27/wish/150211870 RNA is a copy of DNA which leaves the nucleus. RNA are the instructions that ribosomes use to build their proteins.]]> 2017-01-30 13:33:33 UTC https://padlet.com/farnerc1/d97wxg2ewi27/wish/150211870 farnerc1 https://padlet.com/farnerc1/d97wxg2ewi27/wish/150212218 Genes are segments of DNA that control specific traits in an organism]]> 2017-01-30 13:35:00 UTC https://padlet.com/farnerc1/d97wxg2ewi27/wish/150212218 farnerc1 https://padlet.com/farnerc1/d97wxg2ewi27/wish/150212584 Any change in the order of the A,C,T, or G's is called a mutation.  Mutations can occur because of a deletion, an insertion, or a substitution.  Most mutations are harmless but some can cause dramatic changes in an organism. Environmental factors such as sunburns, exposure to cigarette smoke, and radiation can increase the chances that mutations can occur.]]> 2017-01-30 13:36:23 UTC https://padlet.com/farnerc1/d97wxg2ewi27/wish/150212584
