Transposons: Jumping Genes at Cellular levels
Transposons are segments of DNA that can move around to different positions in the genome of a single cell. In the process, they may cause mutations increase (or decrease) the …

Euchromatin : The Packed form of Chromatin
Euchromatin is a lightly packed form of chromatin (DNA, RNA, and protein) that is rich in gene concentration and is often (but not always) under active transcription. Unlike heterochromatin, it …
Heterochromatin: From Chromosome to Protein
The definition of chromatin in eukaryotes, on the contrary of prokaryotes, the DNA is packaged in the form of a nucleoprotein complex called “Chromatin“, which carries the hereditary message. It …
What is Repetitive DNA? Where it is found? What about Renaturation?
The genome is the entire complement of DNA in a cell. Some of this exists as unique DNA (most genes). Other parts exist as repeated stretches – maybe 50 to …

What are Interrupted Genes?
Most eukaryotic genes are interrupted by non-coding or non-translatable sequences known as introns. The coding or translatable sequences are known as exons. Such genes are called split genes / interrupted …
