What is therapeutic cloning?
In the process of cloning DNA or a part of DNA is duplicated. This process is
also called somatic cell nuclear transfer. In this process embryo is utilized
for cloning. Embryo comprises of stem cells which is later employed in
regeneration applications. The embryonic stem cells are renewable and are
pluripotent.
Explain the mechanism of ELISA. What are its uses?
ELISA stands for enzyme linked immunosorbent assay. It is a wet lab type
analytical biochemistry assay. It can detect presence of a substance in a
liquid or wet sample by using one subtype of heterogeneous, solid-phase enzyme
immunoassay. ELISA can be used as ligand binding assays. It is also used as a
diagnostic tool in medicine and plant pathology. Quality check operations can
also be performed in various industries with the help of ELISA.
Explain microarrays. How are they related to DNA?
Microarrays are matrix in the form of arrays where DNA oligonucleotides of DNA
sequences are spotted. They can be used for gene expression profiling, single
nucleotide polymorphism detection, detection of alternative splicing and for
various other purposes. Microarrays have the capability to perform
hybridization of coda with the help of probes. A microarray chip is capable to
perform a large set of genetic related experiments concurrently.
What is the principle behind DNA fingerprinting?
DNA fingerprinting is the technique of genetic fingerprinting. In this
technique, DNA sequence can be used for identification of an individual. The
main application of DNA fingerprinting is forensics. The main principle behind
behind DNA fingerprinting is Polymerase Chain Reaction. This technique is also
popularly known as DNA profiling.
What do you understand by MRI?
MRI stands for Magnetic Resonance Imaging. This technique uses medical imaging
that provides a detailed structure of internal organs; especially soft
tissues.MRI provides good contrast between different soft tissues. A strong
magnetic field is used in MRI which generates images and models of the
specified organ. MRI works on the principle of nuclear magnetic resonance to
generate image of nuclei of atoms inside the body.
What is BMI?
BMI stands for body mass index. This index represents the comparison of the
person's height and weight. The weight of the person is divided by the square
of the person’s height. The SI unit for measuring BMI in kg/sq.m. BMI should
not be treated as a technique for measuring body fat.
