DNA Structure

What is X? Deoxyribose Sugar Phosphate Nitrogen Bases Nucleotide True or False: Cytosine, guanine, thymine and adenine are referred to as phosphates. True False True or False: A nucleotide is made up a sugar, phosphate and two nitrogen bases. True False True or False: Adenine always pairs with guanine. True False True or False: The backbones (outside) of DNA molecules are made up of repeating nitrogen bases and sugars. True False True or False: Covalentbonds hold nitrogen bases together, forming the rings of the DNA ladder. True False Complete the sentences. a) Adenine, guanine, cytosine and thymine are the four nitrogen bases.b) In DNA, cytosine always forms hydrogen bonds with guanine.c) The double coiled shape of DNA is called a double helix.d) In DNA, thymine always goes with adenine.e) Rosalind Franklin found the shape of DNA by using a(n) X-ray.f)Watson and Crick developed the first model of DNA. Given one strand of double-stranded DNA, create the matching strand of DNA. Write in capital letters, for example Thymine = T A T C G T A T A A T C G G C C G C G G C A T T A What is Y?
