Is composed of long similar nucleotide sequence that, as transposons, became scattered throughout the genome.
1- highly repetitive sequence :a- satellitesb- mini-satellitesc- micro-satellites2- moderate repetitive sequence:a- codingb- non coding3-non repetitive sequence
A poly A tail ( adenine ) on messenger RNA could be an example of this phenomenon. AAAAAAAAAAAAAAAAAAAAAAA Transponsons could be another example of repetitive DNA.
repeatitive dna is the unit of satellite dna.thats all
DNA fingerprinting
Telomeres
DNA is double Helix But A Gene is a part of that double helix.
It's called a telomere.
Cancer cells
C refers to the quantity of DNA in a cell, and to explain the c-value paradox,researches examined the repetitiveness of DNA ,and more recently probed and sequenced DNA to understand its properties. 1) Unique DNA and Repetitive DNA 2) Junk DNA

The C-value paradox refers to the lack of correlation between the genome size (DNA content) of an organism and its complexity. For example, some simple organisms like amoebas have genomes larger than more complex organisms like humans. This suggests that genome size alone is not a reliable indicator of an organism's complexity.
Chromosomes 21 and 22 contain long stretches of repetitive DNA, which are unstable sites where rearrangements can occur. The sequencing of human chromosomes 21 and 22 showed that some regions of chromosomes do not code for proteins.
