Homework Answers
1. complementary is the answer.
The nitrogenous bases in the DNA point inward on the ladder and form pairs with bases on the other side.Each base pair is formed from two complementary nucleotides ( purine with pyramidine) bound togetherbby hydrogen bonds. The base pairs in DNA are adenine wih thmine and cytosine with guanine.
2. semi- conservative method is the right answer
Each of the two strands in double-stranded DNA acts as template to poduce two new strands. Repliction relies on complementary base pairing, that is the principle explained by chargaff's rules: adenine(A) always bonds with thymine(T) and cytosine (C) always bonds with guanine(G).

Each of the following statements about the structure of DNA may be either true or false. Choose the appropriate answer for each of these statements. Bonding between adenine and thymine on opposite strands involves two hydrogen bonds. Nitrogenous bases are located on the outside of the double helix: phosphates are located towards the middle of the double helix. Bonding between guanine and cytosine on opposite strands involves three hydrogen bonds. DNA and RNA are structurally different due to the difference...

Question 1 1 pts Why is it important for DNA to have complementary base pairing? O Complementary base pairing allows base pairs to be packed in the most energetically favorable arrangement inside of the double helix structure. O Complementary base pairing will pair a purine with a purine, which are a similar width, thus they are able to hold the sugar-phosphate backbone an equal distance apart along the DNA molecule o Complementary base pairing is only important for maintaining the...

Question 33 2 pts Which of the following statements about the process of DNA replication is true? It involves the enzyme DNA ligase, which corrects point mutations. It utilizes DNA polymerase, which catalyzes the reaction that adds a new nucleotide to the growing strand. The sequence on the new strand is always identical to one of the old parent strands. Adenine pairs with guanine, and cytosine pairs with thymine. Question 34 2 pts The DNA base...
