There are two classes of nitrogen bases called purines (double-ringed structures) and pyrimidines (single-ringed structures). The four bases in DNA's alphabet are: adenine (A): a purine cytosine(C): a pyrimidine guanine (G): a purine thymine (T): a pyrimidine Watson and Crick discovered...
Which RNA is most abundant in animal cells? RNA: Ribonucleic acid, or RNA, is found in all cells just like dexoyribonucleic acid, or DNA. RNA is used to create proteins from the strands of DNA within a cell. Differences Between RNA and DNA ...
aIn fact,throughout the animal kingdom,from sponges to certain types of worms,shellfish,and all vertebrates(creatures possessing a spinal column), there is evidence that transplants of cells or fragments of tissues into an animal are accepted only if they come from genetically compatible or close...
