2. What is a Genome?

  • • A physical/chemical agent that can alter the structure or sequence of DNA
  • Organisms whose cells have a nucleus stored in a nuclear envelope
  • All the DNA that makes up a cell
  • Noncoding DNA(Doesn't make proteins) found between Genes

3. How Do we Sequence Genomes

  • Genapsys Sequencing
  • Whole-Genome Shotgun Approach
  • Chain termination
  • Nanopore Sequencing

4. What are the correct definitions of chromosomal mutations?

  • Inversion- Part of a Chromosome is Inverted. Deletion is where part of a chromosome is deleted. Translocation is where different parts of different chromosomes are found elsewhere. Duplication is where part of one chromosome is copied twice and added to another one.
  • Diversion- Part of a Chromosome is diverted. Deletion is where part of a chromosome is deleted. Translocation is where different parts of different chromosomes are swapped. Duplication is where part of one chromosome is copied twice and added to another one.
