Question

According to molecular sequence data, to which prokaryotic group are eukaryotes more closely related?

Short answer

Eukaryotes are more closely connected to archaebacteria than eubacteria, as indicated in the phylogenetic tree. On the basis of molecular research, eukaryotes are distantly related to eubacteria.

Step-by-step solution

Introduction

The diagram in which it depicts the hypothetical relationship or phylogeny called cladogram.It's used to show how diverse groups of species share similarities and characteristics. A cladogram depicts branches that terminate at a clade using lines.

Closely related groups according to molecular sequence data

The best way to analyze phylogenetic relationships is to use molecular data such as DNA, RNA, or proteins. A clade is a collection of organisms whose members share one or more derived features. Archaea, Bacteria and Eukarya are the three domains represented. It demonstrates how three domains split from a common ancestor. Prokaryotes are divided into two groups: archaea (archaebacteria) and eubacteria. Eukaryotes appear to have evolved from both archaebacteria and eubacteria.

Conclusion

As a result, eukaryotes are more closely connected to archaebacteria than eubacteria, as indicated in the phylogenetic tree. On the basis of molecular research, eukaryotes are distantly related to eubacteria.
