A reporter gene--that is, a gene whose activity is relatively easy to detect--is commonly used to study promoter activity under

a variety of investigative circumstances. recombinant dna technology is used to attach such a reporter gene to the promoter of interest, after which the recombinant molecule is inserted by transformation or transfection into the cell or host organism of choice. green fluorescent protein (gfp) from the jellyfish aequorea victoria fluoresces green when exposed to blue light. assume that you wished to study the regulatory apparatus of the lac operon and you developed a plasmid (p) that contained all the elements of the lac operon except that you replaced the lac structural genes with the gfp gene (your reporter gene). you used this plasmid to transform
e. coli.

Match each light behavior with its definition.
aalyn [17]

1-refraction

2-transmission

3-reflection

4-diffraction

<u>Explanation:</u>

Refraction is the bending of a wave when it enters a medium where its speed is different.Refraction is responsible for image formation by lenses and the eye.

Transmission of light is the moving of electromagnetic waves through a material. This transmission can be reduced, or stopped, when light is reflected off the surface or absorbed by the molecules in the material.

Reflection is when light bounces off an object.Light is reflected when there is a mismatch between materials through which the light is travelling.

Diffraction is the slight bending of light. The amount of bending depends on the relative size of the wavelength of light to the size of the opening.

How does crossing over add to the genetic diversity of sexually reproducing organisms?
neonofarm [45]
<span>Crossover is the first way that genes are shuffled to give rise to genetic diversity. Crossover takes place in sexual reproduction. Chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other. When they break at the same place (locus) in the sequence of base pairs, the result is an exchange of genes called genetic recombination. That is the normal way for crossover to occur. Genetic recombination ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity is created.</span>
