DNA's job is Deoxyribonucleic acid is a molecule composed of two chains that coil around each other to form a double helix carrying the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses. A chromosome is a DNA molecule with part or all of the genetic material of an organism. Most eukaryotic chromosomes include packaging proteins which, aided by chaperone proteins, bind to and condense the DNA molecule to prevent it from becoming an unmanageable tangle. In biology, a gene is a sequence of DNA or RNA that codes for a molecule that has a function. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function.]]> 2018-11-01 14:41:15 UTC https://padlet.com/ethan_horn/3qfmm0i76nvb/wish/299393888 ethan_horn https://padlet.com/ethan_horn/3qfmm0i76nvb/wish/299835387 2018-11-02 15:17:50 UTC https://padlet.com/ethan_horn/3qfmm0i76nvb/wish/299835387 warm up ethan_horn https://padlet.com/ethan_horn/3qfmm0i76nvb/wish/300556702 In cells with a nucleus, as in eukaryotes, the cell cycle is also divided into three periods: interphase, the mitotic (M) phase, and cytokinesis. During interphase, the cell grows, accumulating nutrients needed for mitosis, preparing it for cell division and duplicating its DNA. interphase, prophase, metaphase, anaphase, telophase, cytokinesis. ]]> 2018-11-05 16:18:39 UTC https://padlet.com/ethan_horn/3qfmm0i76nvb/wish/300556702 warm up ethan_horn https://padlet.com/ethan_horn/3qfmm0i76nvb/wish/302130470 The main difference between haploid cells and diploid cells is diploid cells have two complete sets of chromosomes, while haploid cells only have one complete set of chromosomes.

DNA is formed by the nitrogenous bases point inward on the ladder and form pairs with bases on the other side, like rungs. Each base pair is formed from two complementary nucleotides (purine with pyrimidine) bound together by hydrogen bonds. The base pairs in DNA are adenine with thymine and cytosine with guanine.
     The function of DNA is to carry the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses.
     A gene is a segment of DNA that provides the code to construct a protein. The DNA molecule is a long, coiled double helix that resembles a spiral staircase.]]> 2018-11-26 16:15:56 UTC https://padlet.com/ethan_horn/3qfmm0i76nvb/wish/307860371 warm up ethan_horn https://padlet.com/ethan_horn/3qfmm0i76nvb/wish/308844247 James Watson and Francis Crick and it was discovered in 1953
