Answer:
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;
<u>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.</u>
<u />
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.

The bones of your arms are called humerus, while your forearms are composed of two bones, the radius and ulna. The bones of your fingers are called metacarpals and each one of those small bones are called phalanges.
The bones of your shoulders are composed of the clavicle, the bony part seen just right under the neck. Part of the shoulder area is the scapula, which is located at the back part of the body attached to the upper part of the ribs. They are the triangle-shaped bones you feel when you cross your arms at the back.
The bones of your thighs are called femur, they are the largest bones in your body. While the bones of your legs are called tibia and fibula. The bones of your toes are called tarsals and each are composed of smaller bones called metatarsals. Your heels also have bones and they are called calcaneus.
The bones of your pelvis are called Coxal bones as a whole but they are composed of the illium (biggest part of your hips); the pubic bone, located along the reproductive organ; the sacrum and coccyx all located at the base of the spine.
