The slide of stages in starfish development illustrates stages from unfertilized egg to gastrula—typical of echinoderms and chordates that have very little yolk in the egg. Three embryonic cell layers—ectoderm, endoderm, and mesoderm—are established. All adult tissues are derived from these layers.
<span>Sugar - Either ribose or deoxyribose (in RNA or DNA)
Nitrogenous base - Adenine, guanine, cytosine, thymine (only in DNA), uracil (only in RNA)
Phosphates - One to three, two of which are usually hydrolyzed to
provide the energy to attach the nucleotide and form the phosphodiester
