Difference between vertical and horizontal gel electrophoresis?
Horizantal gel electrophoresis is generally used for RNA/DNA based studies, while vertical gel electrophoresis is used for protein based studies.
Role of te in dna extraction?
TE stands for Tris and EDTA. The Tris buffers the water to prevent acid hydrolysis of the DNA/RNA. The EDTA chelates divalent cations that can assist in the degradation of RNA.
What is the difference between an amino acid and RNA?
RNA is a polymer of ribonucleic acids. Amino acids are the monomers of proteins.
The two main types of flow of the genetic information are?
1.central dogma/unidirectional flow of information DNA to rna to proteins 2.central dogma reverse rna to DNA to rna to proteins e.g.in hiv
During transcription the genetic information is rewritten as a molecule of?
During transcription, the genetic information is rewritten as a molecule of
Why use formaldehyde in northern blotting for preparation of gel?
The transfer buffer used for the blotting usually contains formamide because it lowers the annealing temperature of the probe-RNA interaction, thus preventing RNA degradation by high temperatures.And also The RNA samples are most commonly separated on agarose gels containing formaldehyde as a denaturing agent for the RNA to limit secondary structure.
What is the role enzymes play in the procces of gel electrophoresis?
Gel electrophoresis is an analytical method used for the separation of DNA, RNA or proteins based on size.Enzymes are not requires to carry out this process
What is the function of the gel electrophoresis?
Gel electrophoresis is an analytical method used to separate DNA, RNA or proteins based on size
Is electrophoresis part of biotechnology?
Electrophoresis is used to separate molecules based on size and charge. Since biotechnology depends on knowing what you are working with, electrophoresis of proteins, DNA and RNA is a tool used by biotechnologists.
Difference between vertical and horizontal gel electrophoresis?
Horizantal gel electrophoresis is generally used for RNA/DNA based studies, while vertical gel electrophoresis is used for protein based studies.
Why is it difficult to separate large amounts of RNA and DNA using gel electrophoresis?
iono
First reports of the use of sucrose for gel electrophoresis?
Gel electrophoresis is the analysis and separation method of DNA, RNA and proteins. The first reported use of this method was in 1930s.
What are the pros and cons of gel electrophoresis?
Pros: The detection of DNA, RNA and proteins can be done using gel electrophoresis. Gel electrophoresis does not require a large amount of starting material. Cons: difficult to extract samples for further analysis. Harmful materials.
How does electrophoresis work?
Electrophoresis for nucleic acids (RNA and DNA) works by separating segments by their size. This is possible because RNA and DNA are negatively charged, so will move towards the positive charge applied to one end of the gel. The different segments separate because small fragments of RNA or DNA are able to move more quickly through the gel than larger fragments.
What agilent bioanalyzer does and its advantages over traditional gel electrophoresis?
Agilent bioanalyzer uses a microchannel based electrophoresis cell that allow rapid and sensitive investigation of nucleic acid sample.advantages: many samples types can be analyzed on bioanalyzer, including total RNA, labeled RNA, small and micro RNAs, and small and large DNA fragment.
What is the role of DNA and RNA as it relates to Nucleotides?
DNA and RNA are composed of nucleotides.
What is the role of DEPC in RNA isolation?
It inactivate the RNase and prevent RNA to denature.
