Genetics question: What is when two complementary strands of nucleic acid "stick together"?
Homework Answers
Strands of DNA stick together when complementary nucleotides get paired i.e. A-T/G-C by hydrogen bonding. This hydrogen bond is responsible for holding two complementary strands of DNA together.

3. When self-complementary strands of DNA are mixed, they form a double-stranded DNA at low temperatures but dissociate to single strands as the temperature is raised: T(C) A (oligoA-T) This can be observed by an increase in the absorbance of the solutions at 260 nm (The double helix is said to show "hypochromicity" at this wavelength) 10 15 20 25 30 35 40 45 50 0.720 0.732 0.740...

MICROBIAL ECOLOGY: The next set of methods refers to nucleic acid probes. What are these, and how do they work? Select all that are true The term refers to DNA or RNA oligonucleotide complementary to a sequence in a target gene. The probe can be used to identify organisms containing a nucleic acid sequence complementary to the probe. Oligonucleotide probes can be made fluorescent with certain dyes. The probes can be used in the method called FISH.

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...
