Answer:

RFLP analysis.

Explanation:

RFLP (Restriction fragment length polymorphism ) may be defined as a molecular technique used to determine the location of a particular gene in the DNA sequences. The individuals among the population can be easily identified by RFLP analysis.

The restriction enzyme is used for the digestion of DNA sample. The restriction fragments are then visualized by running the fragments on gel electrophoresis. The hybridization between single stranded nucleic acid is not involved in the RFLP.

Thus, the correct answer is option (1).

malfutka [58]

Answer:

osteogenesis imperfecta is an inherited genetic disease that mainly affects the bones.  

Explanation:

Osteogenesis imperfecta is an inherited genetic disease associated with alterations in collagen synthesis, which have been shown to increase the risk to suffer bone fractures. This genetic disorder is characterized by different health problems including, among others, fragile bones, reduced skeletal mass, skin hyperlaxity, malformations in the central nervous system, etc. Clinically, osteogenesis imperfecta must be managed by an interdisciplinary medical team, since patients may present a clinical picture ranging from mild to lethal. In the first place, it is imperative to provide health care to avoid fractures, exercises to maintain muscle mass, exercise to improve motor skills, skincare by specialized dermatologists, etc.

How is mass defect determined?
marysya [2.9K]
<span>Mass defect is the difference between predicted and actual experimentally determined mass. The predicted mass of a sample is found by adding the mass of the neutrons and protons (to be accurate, electrons as well) within that sample, and we know what the individual masses of these particles are so multiplication isn't a problem. This mass is usually higher than what is measured experimentally because some of this mass turns to binding energy with the relationship e is roughly equal to m(c)^2.

If you are asking how we possibly add the masses of all those atoms of the Helium and Hydrogen we experiment with, we do it using the formula (number of atoms * number of protons per atom) + (number of atoms * number of neutrons per atom) + (number of atoms * number of electrons per atom). The number of atoms is found using the total mass of the sample alongside some experimental data.</span><span>
