When 15n-labeled aspartate is fed to animals, the 15n-label rapidly appears in many amino acids. What reactions are occurring to
malfutka [58]

Aspartate + a- keto acid >> Oxaloacetate + a amino acid

This reaction is occur because the a- keto acid in the equation can come from any amino acid, the 15 N from aspartate is rapidly transferred to other amino acids.

15N is symbol use as the isotope of nitrogen with mass number 15. comprises of 0.4 % of stable nitrogen found, so the relative abundance of each in amino acid is simply a reflection of how much is found in nature in general.

This isotopes is enrichment of the labelled amino acids was determined following a previously developed procedure comprising by determination of the spectral purity of the selected natural abundance amino acids.

What is the best description of what viruses are made of?
Mazyrski [523]

The answer is C.

A virus is made up of or consists of a nucleic acid in varying quantity which may either be RNA or DNA.

The nucleic acid is surrounded by a protein shell called a capsid. The word capsid comes from the Latin word  capsa which means box.The capsid and the nucleic acid within it are together referred to as nucleoprotein.The  capsid is made up of small sub units called capsomeres.

In many viruses, the nucleoprotein makes up the whole virus. More complex viruses have one or more further enclosing structures also made mostly of protein. These structures are referred to as envelopes and each envelop is specific to a particular virus.
