A) Deduce the type of genetic material used by
• Cattle --- ADN
• E.coli --- ADN
• Influenza viruses --- ARN (ya q tiene uracilo y este forma parte del ARN)
B) Suggest a reason for the difference between Cattle thymus gland, Spleen and sperm in the measurements of their base composition. ---UNA DIFERENCIA PUEDE SER QUE LA FUNCION DE CADA UNO ES DIFERENTE

C) – Explain the reasons for the total amount of adenine plus guanine being close to 50% in the genetic material of many of the species in the table.--- PORQUE LA MAYORIA DE LAS ESPECIES TIENEN COMO MATERIAL GENETICO ADN

_Identify two other trends in the base composition of the species that have 50% adenine and guanine.--- YEAST AND WHEAT

D)_ Identify a species shown in the table that does not follow the trends in base composition described in C)INFLUENZA VIRUS
_ Explain the reasons for the base composition of this species being different.
--- EL ARN CONTIENE EL URACILO Y LA CITOCINA QUE FORMAN LA MITAD DEL MATRIAL GENETICO Y EL VIRUS DE LA INFLUENZA ES ARN
