Answer:

Rocks

Explanation:

life began at least 3.5 billion years ago, because that is the age of the oldest rocks with fossil evidence of life on earth. These rocks are rare because subsequent geologic processes have reshaped the surface of our planet, often destroying older rocks while making new ones.

Answer:

a) AMP and GMP

Inosinate (IMP) serves as common precursor for the biosynthesis of AMP and GMP. Biosynthesis of AMP from inosinate includes the insertion of amino group from aspartate in GTP dependent manner to form adenylsuccinate followed by its conversion into AMP (adenylate).

Conversion of inosinate into GMP includes dehydrogenation of inosinate into xanthylate (XMP) which is then converted into GMP in a reaction catalyzed by XMP-glutamine amidotransferase enzyme.
