Serga [27]

<em>Answer:</em>

<u>Polymerase Chain Reaction (PCR)</u>

Explanation:

Note that Polymerases Chain Reaction (PCR) is used to amplify food DNA to test for the presence of genetically modified DNA in food products because usually DNA fragments can be isolated from highly processed goods and are sufficiently intact to be amplified by PCR.

The process used by Genetic engineers is <u>called  gel electrophoresis </u>where only a small number of regulatory sequences (promoter and terminator sequences) are used to control the expression of the inserted genes.

Selma is creating a visual representation of the sun and its components for her science fair.
Brilliant_brown [7]

Radiative zone is missing from the three sections of the sun's interior in the diagram.

<h3>What is the Sun's radiative zone?</h3>

A radiation belt. The radiative zone is a layer of dense, highly ionized gases that is constantly being bombarded by gamma rays from the core. It contains 24% helium and 75% hydrogen. Most of the atoms in this region are electron-deficient, so they are unable to absorb photons for convection to the surface.

<h3>What importance is the radiative zone of the Sun?</h3>

The Sun's radiative zone sits in between the convection zone and the core. The convection zone receives radiation from the core's high energy nuclear explosions and the plasma they produce. The radiative zone is where the sun's flares and CMEs originate.
