Answer #1

Nucleotide base pair is defined as two nucleobases or nitrogenous bases that are bonded to each other with hydrogen bonds that act as the building block of the DNA double helix. There are two types of nitrogenous base Purine and Pyrimidine. Purine constitutes Adenine and guanine, Pyrimidine constitutes Cytosine and Thymine or Uracil in case of RNA. Complementary base pairing occurs when Adenine bonds with Thymine with 2 hydrogen bonds and Guanine bonds with Cytosine with 3 hydrogen bonds. In case of RNA Adenine bonds with Uracil with 2 hydrogen bonds. Therefore, corresponding base-pair partner for Adenine is Thymine/Uracil and corresponding base-pair partner for Guanine is Cytosine.

    TRUE OR FALSE: 1. Base-pairing rules apply from one DNA strand to its partner, but not along the sugar-phosphate "handrails" of a DNA strand. 2. DNA polymerase cannot copy point mutations, so they are not passed on from parent cells to daughter cells in cell division. 3. It is not possible for a human gene to work in any other organism. 4.

    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...
