Answer:
Forensic investigations come to sex determination for personal identification . A comparative reliable sex determination analysis approach should be DNA-based rather than to use other conventional methods of sex determination analysis. The real-time polymerase chain reaction (PCR) technology has however become legally acceptable and because it is accurate and its result are reproducible. But still there are knotty situations like what chimerism present in that here an individual possess both male and female specific factors together in their body. Some sex determination analysis most times give a wrong lead and result.
If the criminal is chimeral having two blood groups.

Answer:
When a liquid inside a glass container is measured, the bottom of the meniscus is observed to get an accurate measurement.
Explanation:
The meniscus is the curve seen at the top of the liquid and it can be either concave or convex in shape as per the liquid used. For example, liquids like water produce a concave meniscus. the meniscus is measured by keeping the glassware to the eye level by bringing it to your level or bending down. The measurement is taken from the center of meniscus. For instance, Liquids are measured from the bottom of meniscus and mercury is measured from the top of meniscus.
Answer:
Polymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism).
PCR relies on a thermostable DNA polymerase, Taq polymerase, and requires DNA primers designed specifically for the DNA region of interest.
In PCR, the reaction is repeatedly cycled through a series of temperature changes, which allow many copies of the target region to be produced.
PCR has many research and practical applications. It is routinely used in DNA cloning, medical diagnostics, and forensic analysis of DNA.
PCR:
Polymerase chain reaction (PCR) is a common laboratory technique used to make many copies (millions or billions!) of a particular region of DNA. This DNA region can be anything the experimenter is interested in. For example, it might be a gene whose function a researcher wants to understand, or a genetic marker used by forensic scientists to match crime scene DNA with suspects.
Typically, the goal of PCR is to make enough of the target DNA region that it can be analyzed or used in some other way. For instance, DNA amplified by PCR may be sent for sequencing, visualized by gel electrophoresis, or cloned into a plasmid for further experiments.
PCR is used in many areas of biology and medicine, including molecular biology research, medical diagnostics, and even some branches of ecology.
