What is the gel electrophoresis use for?
to separate proteins and DNA molecules according to their size and charge.
What kind of cell has linear DNA?
All nuclear DNA in eukaryotes is linear DNA. Eukaryotic chromosomes, such as those in human cells, are linear DNA molecules spooled around support proteins called histones.
What makes up the sides of the ladder of a DNA molecule?
The sides of the DNA ladder are alternating deoxyribose (sugar) molecules and phosphate molecules. The DNA bases attach to the sugar molecules.
What does salt do in DNA extraction?
The salt neutralizes the DNA's negative charge with its positive charge while the DNA precipitates.
At the end of s phase each chromosome has how many coiled dna molecules?
2 coiled DNA molecules.
What kind of molecules are transcripts?
DNA Molecules
Transcripts are actually what kind of molecules?
dna molecules
A restriction enzyme is likely to cut which kind of molecules?
DNA molecules. A strand of DNA molecules can be cut to have blunted ends or jagged ends (sticky ends).
What is the gel electrophoresis use for?
to separate proteins and DNA molecules according to their size and charge.
What is the net charge of phosphatidylserine at pH 7?
DNA molecules are connected via a 5'-3' phosphodiester linkage to ribose molecules. The phosphate group within this linkage is contains a negatively charged oxygen atom at a PH of 7. This gives DNA its charge.
How does NaCl help extract DNA?
NaCl stabilizes the the double helical structure of DNA. It also provides Na+ that neutralise the negative charge present on DNA. Due to the negative charge the DNA molecules repell each other. When the charge is neutralized the DNA molecule come together and could be precipitated.
What is the main difference between DNA helicases and DNA molecules?
DNA helicases are proteins, while DNA molecules are nucleotides.
How does DNA molecules differ from daughter DNA molecules?
Daughter moloqules are newer than DNA moloqules
How does DNA charge affect movement in electrophoresis?
DNA molecules have a negative charge due to the phosphate groups in their backbone. In electrophoresis, an electric field is applied across a gel matrix, causing DNA fragments to migrate towards the positive electrode. The negatively charged DNA molecules are attracted to the positive electrode and move through the gel at different rates based on their size, with smaller fragments moving faster than larger ones.
What does DNA determine in a cell?
The molecules of DNA contain the genetic info that determines the structure of a cell and the way it functions.
What kind of cell has linear DNA?
All nuclear DNA in eukaryotes is linear DNA. Eukaryotic chromosomes, such as those in human cells, are linear DNA molecules spooled around support proteins called histones.
DNA replications begins in areas of DNA molecules called what?
DNA replication begins in areas of DNA molecules are called origins of replication.
