Methods fo Complementary base pairing properties of DNA

Click For Summary

Discussion Overview

The discussion revolves around methods that utilize the complementary base pairing properties of DNA, particularly focusing on techniques related to DNA-DNA and DNA-RNA hybridization. Participants explore various methods covered in recombinant DNA technology and genomics, as well as additional techniques from literature.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant lists methods including Polymerase Chain Reaction (PCR), Gene Cloning, Sanger Method, Site-directed Mutagenesis, and DNA polymorphisms, questioning their correctness.
  • Another participant corrects that DNA polymorphisms is not a method but can be identified using certain methods, hinting at additional techniques related to hybridization.
  • Methods such as Northern and Southern blotting, DNA fingerprinting/typing, Maxam-Gilbert sequencing, and pyrosequencing are proposed as valid techniques.
  • A participant suggests that the Sanger method is the opposite of the Maxam-Gilbert method in terms of hybridization.
  • There is a clarification regarding the naming of Southern blotting, with a participant asserting it was named after a person, while others note that the other methods were not.
  • A question is raised about whether viruses can be counted in base pairs or only in nucleotides, with a response indicating that base pairs refer to pairs of nucleotides joined by hydrogen bonds.
  • Another participant suggests rephrasing the question regarding viruses for clarity.

Areas of Agreement / Disagreement

Participants express differing views on the classification of DNA polymorphisms and the naming conventions of blotting techniques. There is no consensus on the completeness of the methods listed, and the discussion remains unresolved regarding the best way to count viruses.

Contextual Notes

Some methods mentioned may depend on specific definitions or contexts, and there are unresolved questions about the classification of techniques and the terminology used in the discussion.

Hi,

My question asks to:

List the methods that use the complementary base pairing properties of DNA (hint; any methods that use DNA-DNA or DNA-RNA hybridization); include those that we covered in Recombinant DNA Technology and Genomics. You can include a few extra ones from the book.


My Answer

The methods that used complementary base pairing properties of DNA include Polymerase Chain Reaction(PCR), Gene Cloning, Sanger Method, Site directed Mutagenesis, and DNA polymorphisms.

Is this correct :confused:

Thank You :smile:

The method you listed are ok but DNA polymorphisms is not a method; however you can id DNA polymorphisms using certain methods. Hint: finger.

Also most of the techniques you listed are based on the same "PCR" idea. There is more to it.

With this statements "DNA-DNA or DNA-RNA hybridization" in mind, there a least 3 major methods/techniques that you are missing. One is an older method that was used to measure the "relatedness" among organism, at least in bacteria. The other two are basically the same as a method used in Protein science. Hint: Western.

Hi,

Are Northern and Southern blotting okay, as well as DNA fingerprinting/typing, Maxam-Gilbert sequencing, and pyrosequencing.

Thank You :smile:

You should read on the Maxam-gilbert sequencing method. You will get an answer. In terms of hybridization, the Sanger method is the opposite of the Maxam-Gilbert method.

Northern and southern blots (the N and S should not be capitalized because it is not named after a person), DNA fingerprinting/typing and pyrosequencing are okay.

You should also look into global gene expression profiles methods.
 
Southern was the original blot method, and *was* named after a person. The other two weren't named after people.

Hah cranky! I should of remember that! it was a question during somebodies defence.
 
Hi,

Can viruses be counted in base pairs or are they only counted in nucleotides? If they are only counted in nucleotides is there any other way to convert them to base pairs?

Thank You
 
nucleotides and base pairs are basically the same. The only difference is that base pair refers to two nucleotides join together by an hydrogen bound.

Viruses can be either RNA or DNA, and the DNA or the RNA is double or single stranded.

It would be good if could rephrase your questions with better terms.
