AIIMS 2019 Botany Archaebacteria Assertion Reason Question
Assertion: Archaebacteria are more similar to eukaryotes rather than eubacteria.
Reason: Archaean genome is more similar to eukaryotic genome rather than bacterial genome
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false
If both assertion and reason are false.
Correct Answer
Detailed Explanation
Archaebacteria share several key features with eukaryotes, such as the presence of introns in their genes and similarities in their transcription and translation processes, indicating a closer evolutionary relationship. Their metabolic pathways, including those involved in methanogenesis and certain aspects of cellular respiration, also align more closely with eukaryotic processes than with those of bacteria, reinforcing this similarity. Other options are not applicable as they do not provide relevant information or alternatives regarding the relationship between archaebacteria, eukaryotes, and bacteria. Understanding these distinctions is crucial for grasping the evolutionary tree of life and the classification of organisms.
