Answer:

Nowadays, molecular pieces of evidence are used to show the similarity between two species as the universal molecule- DNA is present in all living organism from lower to higher organisms which code for the amino acids of the proteins.

The differences and similarities between genomes of two different species confirm relatedness as a mutation in genes can show evolutionary patterns which can be summarized as:

  1. differences between base sequences can show the degree of divergence.
  2. a large number of differences means species diverged long ago.
  3. more similarity in sequence means species are more closely related.

Thus, molecular evidence is used to show species relatedness.

Maurinko [17]

Answer:

El cuadro no está presente pero las diferencias principales entre células eucariotas y procariotas son:

Eucariotas:

Tienen núcleo

Tienen organelas

Tienen Vacuolas

Tienen Citoesqueleto

Tienen Cloroplastos

El ADN está asociado a proteínas

El ADN es lineal

Presentan mitocondrias

Presentan un sistema de endomembranas

Procariotas:

No tienen núcleo

No tienen vacuolas

No tienen cloroplastos

No tienen organelas

El ADN no está asociado a proteínas

El ADN es circular

Presenta mesosomas

Explanation:

Las células procariotas son más primitivas que las eucariotas, por ende, sus estructuras son más simples. Las células procariotas están en organismos unicelulares tales como las bacterias, mientras que las células eucariotas están en organismos unicelulares y pluricelulares como en plantas, animales, u hongos. La diferencia más notoria entre ambos tipos de células es la ausencia de núcleo en las procariotas haciendo que el ADN está disperso en el citoplasma mientras que en las células eucariotas, el ADN está dentro del núcleo celular.
