Ohm's law states that the electrical current (I<span>) flowing in an circuit is proportional to the voltage </span>(V) and inversely proportional to the resistance<span> (R)</span><span>. Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change. Similarly, increasing the resistance of the circuit will lower the current flow if the voltage is not changed. The formula can be reorganized so that the relationship can easily be seen for all of the three variables.</span>

Genes can be modified by number of ways. Now a days many tools have been developed and we can easily do genetic modifications.
homologous recombination. example in yeast
plasmid based modification. example in bacteria
crispr mechanism
tallen and zinc finger motifs
restriction enzymes
epigenetic enzymes.
rna interference.
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.
