Micro and Mini Satellites in Genomics

The video tutorial discusses micro and mini satellites in the genome, explaining their classification as tandem repeats, differences in size and frequency, and their genomic locations. It covers their origins, regulatory functions, and applications in modern analysis, such as DNA fingerprinting and forensic science.

What are micro and mini satellites primarily composed of?

• Proteins

• RNA sequences

• Lipids

• DNA sequences

How do micro satellites differ from mini satellites in terms of size?

• Micro satellites are larger

• Mini satellites are larger

• They are the same size

• Size varies depending on the organism

Where are mini satellites most commonly found in the genome?

• Only in mitochondrial DNA

• In both coding and non-coding regions

• In non-coding regions

• In coding regions

What is the primary role of micro and mini satellites in gene expression?

• Protein synthesis

• Cell division

• Gene regulation

• Energy production

How do micro satellites contribute to genomic diversity?

• By being stable and unchanging

• Through frequent mutations

• By coding for multiple proteins

• By preventing gene expression

Which type of satellite is more prone to mutations?

• Micro satellites

• Neither are prone to mutations

• Mini satellites

• Both are equally prone

What is a common application of mini satellites in modern analysis?

• Cellular respiration

• Photosynthesis

• DNA fingerprinting

• Protein synthesis

Which satellite type is predominantly used in forensic science?

• Micro satellites

• Mini satellites

• Both are used equally

• Neither are used

What is the CODIS marker used for?

• Genomic sequencing

• Forensic analysis

• Protein synthesis

• Cell division

In what way do micro satellites affect genomic evolution?

• By increasing mutation rates

• By stabilizing the genome

• By preventing DNA replication

• By decreasing genetic diversity
