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.

DNA profiling does not use restriction enzymes to cut the DNA. Instead it uses the polymerase chain reaction (PCR) to produce many copies of specific STR sequences. PCR is an automated procedure that generates lots of copies of a specific sequence of DNA

It has the ability to start in several parts of the body at once.

Hence the correct answer is" Kaposi's Sarcoma "

Which spinal plexus gives rise to the phrenic nerve, and what organ does this nerve supply?.
givi [52]
  • The phrenic nerve is derived from the cervical plexus and receives innervation from the C3, C4, and C5 nerve roots. It is the longest branch of the cervical plexus.

Why does phrenic nerve supply diaphragm?

  • The C3-C5 spinal nerves in the neck give rise to the phrenic nerve, a mixed motor and sensory nerve.
  • The diaphragm, the main muscle of respiration, is exclusively controlled by the nerve, making it essential for breathing.

What organ does this nerve supply?.

  • The jejunum receives both intrinsic and extrinsic nerve supply.
  • The preganglionic parasympathetic and postganglionic sympathetic branches of the celiac plexus provide the autonomic extrinsic supply.
  • These neurons go via branches of the major vessels from the mesentery into the jejunum.

What are the 4 types of nerves?

It is conventional, however, to describe nerve types on the basis of their function: motor, sensory, autonomic or cranial.

  • Motor Nerves.
  • Sensory Nerves.
  • Autonomic Nerves.
  • Cranial Nerves.
