Question

Chlorarachniophyte and cryptophyte algae contain three sets of genetic material: the nuclear genome, the chloroplast genome, and a set of genes found in the nucleomorph. What, in terms of the endosymbiotic hypothesis, is represented by the nucleomorph genes?

Answer 1

Endosymbiotic Hypothesis

Explanation:

• The hypothesized process by which prokaryotes produced ascend to the primary eukaryotic cells is known as endosymbiosis
• The Positively positions among the most significant developmental occasions
• Endosymbiotic hypothesis, that attempt to clarify the beginnings of eukaryotic cell organelles, for example, mitochondria in animals and parasites and chloroplasts in plants
• The endosymbiotic theory are The Mitochondria and chloroplasts have a single roundabout chromosome
• Mitochondria and chloroplasts separate by mitosis
• Mitochondria and chloroplasts have 70S ribosomes

Answer 2

Endosymbiotic hypothesis

Explanation:

Remnant genes from the nucleus of a eukaryotic algal endosymbiont

• The endosymbiotic hypothesis explains the origin of mitochondria and plastids through the engulfment of bacteria into eukaryotic cells
• Nucleomorphs are the smallest nuclear genomes which are remnant nuclei of algal endosymbionts that were engulfed by non photosynthetic host eukaryotes
• These organelles are found in Chlorarachniophyte and cryptophyte algae,where they evolved from green and red algal endosymbionts respectively
• Nucleomorph of Chlorarachniophyte and cryptophyte algae cells has been greatly reduced through the combined effects of gene loss and intracellular gene transfer
