He compared the composition of DNA to these proteins and pointed the distinct differences. He discovered a combination of Protein, DNA, and RNA near the nucleus and named it nuclein. During Miescher's lifetime, no one discovered the use of Nuclein and Mieschers guess was that it stored Phosphorous atoms.

Their work is important because now people could understand how it grows and could begin to grow DNA molecules themselves. ]]> 2018-04-04 15:29:24 UTC https://padlet.com/1028012/m592we1hhits/wish/248544047 1028012 https://padlet.com/1028012/m592we1hhits/wish/248544810 DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group, and a nitrogen base. The four types of nitrogen bases are thymine, guanine, adenine, and cytosine. The order of these bases is what determines DNA instructions, or genetic code.]]> 2018-04-04 15:30:57 UTC https://padlet.com/1028012/m592we1hhits/wish/248544810 1028012 https://padlet.com/1028012/m592we1hhits/wish/248545300 The nucleotides of DNA are Thymine. Cytosine, Adenine, and Guanine.
The 3 parts of nucleotides are Nitrogenous Base, the pentose sugar, and the phosphate group.

The hydrogen bonding between complementary bases holds the two strands of DNA together, are not chemical bonds.]]> 2018-04-04 15:32:45 UTC https://padlet.com/1028012/m592we1hhits/wish/248545629
