- Imagine the four basic components of gene regulation are DNA, RNA, proteins, and small molecules.

Researchers have determined the number of miRNA genes possessed by different species and have made the following observations: Q. The number of miRNA genes found on a chromosome is not correlated with chromosome length. In other words, longer chromosomes do not necessarily have more miRNA genes.arrow_forwardGiven that ncRNA can have separate protein interaction sequences and nucleotide interaction sequences, do you think a single ncRNA could guide different proteins to the same DNA sequence?
