Still, the Home uses the Google Assistant (Google's aptly named digital assistant built into the Home and Android phones like the Pixel -- and now ) to respond to voice commands conversationally, something Google was eager to demonstrate when the Google Home made its initial debut back in May 2016.
Amino acids were the vital molecules that formed in this experiment and supported this hypothesis for the origin of life. An amino acid is a molecule that contains two functional groups, an amine and a carboxylic acid, as shown in Figure 1. In this illustration there is an additional group called the side chain, designated with an R. The variation seen in naturally occurring amino acids arises from differences in this side chain.
Nucleic Acids. Amino acids on the other hand are the building blocks of our proteins. All proteins are made of alpha amino acids. They consist of a carboxylic acid (-COOH) and an amino (-NH2) functional group attached to the same tetrahedral carbon atom. This carbon is the a-carbon. Distinct R-groups, that distinguish one amino acid from another, also are attached to the alpha-carbon (except in the case of glycine where the R-group is hydrogen). The fourth substitution on the tetrahedral a-carbon of amino acids is hydrogen.
