Answer:

Polymerase chain reaction (PCR) test is used to duplicate traces of DNA from any living form, for identification purposes.  The correct sequence is 1, 3, 2; based on the options given.

Explanation:

The steps to be followed for the PCR procedure are:

<em>Denaturation</em>

Option 1.  Involves incubation at 94°C to denature DNA strands into single strands by breaking of weak hydrogen links

<em>Annealing</em>

Option 3.  Temperature is lowered to 60°C to allow primers joining their similar DNA sequences.

<em>Elongation</em>

Option 2.  Incubate at 72°C to promote the extension of the DNA strands, actually extending them.

Tanya [424]
False the process is reversed. Photosystem ll happens before photosystem l. I know that's weird but it's true. In photosystem ll which happens first it makes the energy carriers for ATP Synthase to happen in Photosystem l which is the next phase. Hope this helped!

eimsori [14]

Shortly after gastrulation, the body and organs of the embryo begin to form. This process is called <u>embryogenesis.</u>

<u></u>

  • The process by which an embryo transforms into a fetus is known as embryogenesis.
  • The three germ layers that eventually give rise to the various organs in the animal body are formed as a result of gastrulation.
  • Embryogenesis is the name of this process. As a result of differentiation, organs emerge from the germ layers.
  • The process of creating and growing an embryo from a zygote (zygotic embryogenesis) or a somatic cell is known as embryogenesis (somatic embryogenesis).
  • An incredibly well-organized series of cell division, expansion, and differentiation takes place during embryo development.
