Studying non-coding RNA (ncRNA) is super important for understanding genetics. Here’s why:

1. Lots of It: About 98% of our DNA doesn’t code for proteins. This shows that ncRNA plays a big role in managing our genes.

2. What It Does: NcRNAs help with many important tasks, like:

   • Gene Regulation: For example, microRNAs help control about 60% of the genes that make proteins in humans.
   • Changes to Gene Structure: Long non-coding RNAs can affect how DNA is arranged in our cells.
   • Making Ribosomes: Ribosomal RNA is a type of ncRNA that makes up around 80% of RNA in cells. Ribosomes are the parts of the cell that help make proteins.

3. Health Issues: Changes in how ncRNAs work are linked to different health problems, such as:

   • Cancer: Over 50% of genes that can cause cancer are controlled by ncRNA.
   • Brain Disorders: Some ncRNAs are connected to conditions like Alzheimer’s and autism.

By understanding ncRNA, we get better insights into how genes work and how they can affect our health. This helps us see the bigger picture of genetics.
