Some researchers says that "The DNA sequences of the dark genes are very rich in G and C molecules, two of the four bases molecules that make DNA. We need to fully understand the concept of dark DNA and it's effect on biological evolution.
The dark matter in the genome is long, winding strands of DNA without obvious functions that have not been recognized for a long time. The researchers found that the sequences of DNA that do not encode proteins remain identical in a wide range of animals by removing some of these elements that are not preserved and found that these sequences guide brain growth by adjusting the expression of protein genes.
Dark DNA is a strange phenomenon in molecular evolution ..... Until now, dark DNA appears to exist in two very different and very diverse species of animals. But how its spread remains unclear. Can all animal genetic factors contain dark DNA, and if not, what makes jars and birds unique?
The most exciting puzzle that will be worked out is how dark DNA can affect the evolution of animals.
