Pseudogene
Videos
Pseudogenes are nonfunctional segments of DNA that resemble functional genes. Pseudogenes can be formed from both protein-coding genes and non-coding genes. In the case of protein-coding genes, most p

Junk DNA
Videos
Junk DNA is a DNA sequence that has no known biological function. Most organisms have some junk DNA in their genomes—mostly pseudogenes and fragments of transposons and endogenized viruses—but it is p
Pseudogene
…sequence analysis finds gene-like sequences that lack regulatory sequences or are incapable of producing a functional product. Pseudogenes are a type of junk DNA. Most non-bacterial genomes contain many pseudogenes, often as many as functional genes. This is not surprising, since various biological processes are…
Francis Crick and others promoted the idea that transposons were examples of selfish DNA and were responsible for the proliferation of junk DNA.
