What is satellite DNA?
Q: What is satellite DNA?
A: Satellite DNA is a type of DNA that contains repeating, non-coding sections of DNA. It is a type of tandem repeat, meaning that the repeats sit next to each other, in tandem.
Q: What are minisatellite and microsatellite DNA?
A: Minisatellite and microsatellite DNA are also types of tandem repeat DNA, which means that they consist of multiple copies of the same base-pair sequence lying end-to-end.
Q: What is the main component of centromeres?
A: Satellite DNA is the main component of centromeres.
Q: What is heterochromatin?
A: Heterochromatin is a type of tandem repeat DNA that sits on chromosomes around the centromeres and elsewhere. It is "transcriptionally inactive", meaning that it does not code for proteins.
Q: Is satellite DNA coding or non-coding DNA?
A: Satellite DNA is non-coding DNA, meaning it does not code for proteins.
Q: Is satellite DNA transcriptionally active?
A: Satellite DNA is usually transcriptionally inactive, meaning it doesn't code for proteins.
Q: What is the most common type of tandem repeat?
A: The most common type of tandem repeat is the heterochromatin, which sits on chromosomes around the centromeres and elsewhere.
