· Cattle--ADN
· E.coli--ADN
· Influenza viruses--ARN (porque tiene Uracilo)
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 el tipo de material genético de casi todas las especies es 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.COMO EL TIPO DE MATERIAL GENÉTICO DEL VIRUS DE INFLUENZA ES ARN, POSEE URACILO, Y EL URACILO CON LA CITOSINA FORMAN MAS DEL 50% DEL MATERIAL GENÉTICO.
