What is the smallest part or fragment of an atom?
The smallest part or fragment of an atom is the Electon.
What are the uses of electrophoresis?
Electrophoresis is a technique used for the separation of biological molecules based on their movement due to the influence of a direct electric current. The technique was pioneered in 1937 by the Swedish chemist Arne Tiselius for the separation of proteins. It has now been extended to the separation of many other different classes of biomolecules including nucleic acids, carbohydrates and amino acids. Electrophoresis has become increasingly important in the laboratory for basic research, biomedical research and in clinical settings for the diagnosis of disease. Electrophoresis is not commonly used to purify proteins in large quantities because other methods exist which are simpler, faster, and more efficient. However, it is valuable as an analytical technique for detecting and quantifying minute traces of many biomolecules in a mixture. It is also useful for determining certain physical properties such as molecular mass, isoelectric point, and biological activity.
Why does the DNA fragment size change as you move from the cathode to the anode?
The DNA fragment size decreases as it moves from the cathode to the anode. This is due to the negative charge of the DNA moving against the positive charge of the cathode.
The smallest fragment of a theme that forms a melodic-rhythmic unit is called?
a motive
What is metastable ion peak?
A metastable ion peak is a broad peak which appears at non-integral values of m/e in a mass spectrum. It is formed by a fragment ion. An unstable molecule such as an alcohol can undergo fragmentation during ionization ( collision with high energy electrons in ionization chamber of the mass spectrometer ) to give rise to a fragment ion. This fragment ion is also called the metastable ion.
Which fragment moves the furthest in gel electrophoresis?
The smallest fragment will more furthest in the gel.
What is used to cut the DNA into fragment so its sequence could be read?
the process is called gel electrophoresis.
Will your D1S80 fragments be separated by gel electrophoresis if you have a 200 base pair and a 400 base pair?
Yes, gel electrophoresis separates fragments based on their size. Therefore it will be able to separate a 200bp fragment from a 400bp fragment provided you use the correct gel composition (as this affects the sensitivity to size differences).
Analysis of DNA fragments in gel electrophoresis involves what?
i)- the size of the DNA fragment, ii)- the density of the agarose gel, iii) - the intensity of the migratory electric field.
How does gel electrophoresis is used to make a DNA fingerprint?
Gel electrophoresis separates DNA fragment on the basis of their size. In DNA fingerprinting or DNA typing given sample is cut up with restriction enzymes and run through electrophoresis and results are analyzed to check for DNA polymorphism between the given sample and a sample form suspect. In nutshell gel electrophoresis is boon for the people in forensics.
How can electrophoresis gels be used to implicate any suspect in a crime?
Electrophoresis per se cannot be used to implicate a suspect. Rather, electrophoresis is merely one of many analytical techniques which may be applied to a specific question, being posed by a an investigator. The value of electrophoresis is nil outside the data quality objectives (DQOs) presented by the investigating team, and the QA/QC program of the analyzing laboratory. Without QA/QC, in the lab, and without appropriate DQOs, electrophoresis is no more capable of implicating a suspect than a ouija board. Laboratories cannot perform in the real world as seen on TV's CSI, and real CSIs would go to jail if they pulled some of the stunts seen on the TV series.
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.
The sequence of a DNA fragment can be determined by observing the order of the fluorescent bands on the electrophoresis gel?
There is no answer you are all being lied to you are all in the matrix this is the matrix this is me morphius and this is the matrix do you take the blue pill or te red pill
What information can you determine from gel electrophoresis?
You can estimate the concentration of DNA or RNA in your extract as well as the size of the fragment(s) isolated by comparing to a known molecular marker/DNA ladder. 2 strand are smaller than 3 strand
Is 'A year that was' a sentence or a fragment?
Fragment.
Does a single band form in electrophoresis gel if all the DNA fragment is of same size?
if all the fragments are of same size (same fragment length), it will form a single band on an agarose gel. unless you are using other gel electrophoresis technique like DGGE, then only it will separate fragments with different sequences, but that will depends on the resolution power too.
Is (how are you) a fragment?
It is a fragment that shouldn't be capitalized or punctuated.
