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 answer is Proteomics.
<u>Proteomics</u> is a discipline of study that involves an examination of proteins and how the proteins encoded by genes interact to produce cell and tissue types.
What is Proteomics?
The extensive study of proteomes is known as proteomics. An organism, system, or biological setting produces a set of proteins known as a proteome. We might speak of an organ or a species' proteome (like that of Homo sapiens) (for example, the liver). The proteome is dynamic; it varies from cell to cell and alterations occur over time. The underlying transcriptome is somewhat reflected in the proteome. However, in addition to the relevant gene's expression level, a number of other factors also affect protein activity, which is frequently measured by the rate at which the processes in which the protein is engaged react.
Proteomics is employed to look into:
- When and where do proteins expressed.
- rates of protein synthesis, degradation, and abundance at steady state.
- how proteins are altered, for as by phosphorylation and other post-translational modifications (PTMs).
- the transfer of proteins among subcellular spaces.
- protein involvement in metabolic processes.
- what interactions proteins have with one another.

I wish i could help but i’m not sure :(
