Answer:

Polyphenol oxidase (PPO) activity was determined by measuring the initial rate of quinone formation,

as indicated by an increase in the absorbance units (AUs) at 420 nm. An increase in absorbance of 0.001 min−1 was taken as one unit of enzyme activity

According to the trichromatic theory of color vision, the eye has cones sensitive to colors associated with ___________.

saveliy_v [14]

Answer: The correct option is c. red, green and blue.

Red, green and blue are primary colors. The theory of trichromatic theory is derived from the color mixing and the color matching explanations. According to the experiment in this theory, the individual person having normal vision of color requires three wavelengths of the primary colors to match with any other color in the visible spectrum. This led to finding of color vision which is based on the activities of three different receptors each having a different sensitivity of the peak. The three receptors are each sensitive towards colors red, blue and green respectively.

Can someone explain the process of RNA editing?

Talja [164]

The process of RNA editing is the alteration of the sequence of nucleotides in the RNA after it has been transcribed from DNA, but before it is translated into a protein. RNA editing occurs by two distinct mechanisms:Substitution editing and Insertion/deletion editing.

Substitution editing is the chemical alteration of individual nucleotides. These alterations are catalyzed by enzymes that recognize a specific target sequence of nucleotides:

*Cytidine Deaminases that convert a C in the RNA to uracil.

*adenosine deaminases that convert an A to inosine,which the ribosome translates as a G.Thus a CAG codon (for Gln) can be converted to a CGG codon (for Arg).

*Insertion/deletion editing is the insertion or deletion of nucleotides in an RNA.

These alterations are mediated by guide RNA molecules that base-pair as best they can with the RNA to be edited and serve as a template for the addition( or removal) in the target.
