Study Notes
Factors Influencing DNA Movement in Gel Electrophoresis
- The main factor influencing the rate of movement for DNA through the agarose gel is the size of the DNA molecule, with smaller DNA molecules moving faster than larger ones.
- The fast movement of DNA through the agarose gel is influenced by the size of the DNA molecule, with smaller molecules moving faster.
Function of Standard Molecular-Weight Markers (Ladder)
- The function of the standard molecular-weight markers (Ladder) in gel electrophoresis is to provide a set of DNA molecules of known sizes, allowing for the estimation of the size of unknown DNA molecules.
Net Charge of Nucleic Acids
- The net charge of all nucleic acids in DNA molecules is negative due to the phosphate groups.
Main Component for Separation of DNA and RNA Fragments
- The main component used for the separation of DNA and RNA fragments in agarose gel electrophoresis is agarose.
Type of Gel Used for Separation
- Agarose gel is specifically used for the separation of DNA and RNA fragments in gel electrophoresis.
