Why do researchers use rRNA in investigations of relationships between taxa that diverged hundreds of millions of years ago? See Concept 26.4 (Page 564) View Available Hint(s) Why do researchers use rRNA in investigations of relationships between taxa that diverged hundreds of millions of years ago? See Concept 26.4 (Page 564) rRNA is traditionally the nucleic acid chosen for recent comparisons. rRNA cannot mutate. rRNA is never the nucleic acid chosen for comparisons. rRNA changes at different rates in different taxa. DNA coding for rRNA changes relatively slowly

DNA coding for rRNA changes relatively slowly

Explanation:

The ribosomal ribonuclei acid( rRNA ) is used for Ribosome synthesis. Ribosomes is the organelle for  translation of encoded amino acids in protein  synthesis in  the cells. The gene that codes for rRNA is called rDNA.Thus must of the functionalities of rDNA are encoded rRNA. Therefore researchers use rRNA for comparison investigations  because;

1.The coding region on the rDNA is highly conserved, with low rate of polymorphism, thus rDNA for rRNA  transcriptions pathways is relatively slow compare to the one of  high rate of  polymorphism.

2. Consequently the conserved region( well preserved amino acid sequence) of the rDNA encoded in rRNA, with  low polymorphism, and therefore  slow transcription pathways  enabled the use of rRNA for investigations of relationship between taxa. Since  rRNA is present across all organisms,prokaryotes and eukaryotes  the highly conserved coded region of low mutation and therefore slow changes, enable accurate comparison.

videntify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.
