DNA and genome

• Why is it important to understand the human genome?

  It helps in searching for disease-linked genes
• Where are chromosomes found in cells?

  In the nucleus
• What do chromosomes contain?

  The molecule DNA
• Why is DNA referred to as genetic material?

  It determines our inherited features
• What is the structure of DNA described as?

  A double helix
• What is each strand of DNA made of?

  A polymer of smaller molecules
• What is a gene?

  A small section of DNA on a chromosome
• What does the blood type gene determine?

  The sequence of amino acids for blood type protein
• How many genes does chromosome 9 have?

  Well over 700 different genes
• What do both chromosomes in a pair have in common?

  They have the same genes
• What is the genome?

  The entire genetic material of an organism
• What is the human genome?

  The entire genetic material that makes a human
• What is one benefit of studying the human genome?

  It helps search for disease-linked genes
• How can understanding the human genome help with inherited disorders?

  It aids in understanding and treating them
• How can the human genome be used in tracing human migration?

  It helps discover ancestry and migration patterns
• What is the relationship between genes and proteins?

  Each gene encodes a specific protein
• How does the structure of DNA relate to its function?

  The double helix structure allows for stability and replication
• Why is understanding the human genome crucial for disease prevention?

  It helps identify genes linked to diseases
• What role do chromosomes play in heredity?

  They carry genetic information from parents
• Why is the double helix structure significant for DNA?

  It provides stability and allows replication
• How are proteins synthesized from genes?

  Genes encode the sequence of amino acids
• What are the implications of genetic research on human health?

  It leads to better treatments and prevention
• How does genetic data inform historical human migration patterns?

  It helps trace ancestry and migration routes
