What is added to make the DNA clump together?
To make DNA clump together, a salt solution is often added, which neutralizes the negative charges on the DNA backbone. This allows the DNA strands to come closer together and aggregate. Additionally, the use of alcohol, such as ethanol or isopropanol, can precipitate the DNA, facilitating its clumping and making it visible for collection.
Why chilled ethanol is added for DNA isolation?
to precipitate extracted DNA
As a DNA molecule splits what is added to the exposed base on the original molecule?
During DNA replication, a complementary nucleotide is added to each exposed base on the original DNA molecule. This process ensures the formation of two identical DNA molecules.
Where is the dna placed in gel electrophoesis apparatus?
In gel electrophoresis, the DNA is placed in wells at one end of the gel. When an electric current is applied, the DNA molecules move through the gel towards the opposite end based on their size. Smaller DNA fragments move faster and travel further through the gel compared to larger fragments.
Why extraction buffer is added for isolation of DNA?
Extraction buffer is added to isolate DNA because it helps break down the cell membrane and nuclear envelope to release the DNA. It also helps in denaturing proteins that may interfere with DNA extraction, and stabilizes the DNA once it is released from the cell.

Which enzyme is added to attach the DNA backbone between vetor and foreign DNA that have formed bases pairs at sticky ends during of recombinant DNA?
DNA ligase is added.
How can gel electrophoresis be used to separate and analyze DNA fragments?
Gel electrophoresis separates DNA fragments based on size by applying an electric field to move them through a gel matrix. Smaller fragments move faster and travel further, allowing for analysis of DNA size and quantity.
Why do shorter strands of DNA move faster in gel electrophoresis?
Shorter strands of DNA move faster in gel electrophoresis because they can travel through the pores of the gel more easily than longer strands. This is because shorter strands experience less resistance and can navigate through the gel matrix more quickly.
What enzyme is added to attach the DNA backbone between vector and foreign DNA?
DNA ligase
Why chilled ethanol is added for DNA isolation?
to precipitate extracted DNA
Why is alcohol added the DNA solution?
Alcohol is added to the DNA solution to help precipitate the DNA out of the solution. This allows the DNA to be separated from other cellular components such as proteins and lipids. The DNA can then be collected and further analyzed or used in experiments.
Why rna virus is more mutant than dna virus?
during replication RNA-polimeraze it make a lot of erros.In this ways RNA viruses it mutate faster than DNa viruses.
What enzyme called is added to attach the DNA backbone between vector and foreign DNA?
DNA ligase
In regards to analyzing DNA with gel electrophoresis Are DNA fragments separated by size?
Yes, electrophoresis involves seperation depending upon size by applying charge to the DNA sample loaded which then travels form negative to positive eletrode as DNA being negatively charged. Thus the small sized molecules will travel faster as compared to larger molecules.
Where do fish get there glow?
Glofish are really Zebra Danios that have had a jellyfish gene added artificially to make them glow.
What kind of precipitate is formed when alcohol is added to denatured DNA?
When alcohol is added to denatured DNA, a white stringy precipitate of DNA will form. The DNA precipitates out of the solution because of its insolubility in alcohol, allowing it to be separated from the rest of the solution.
