B6: Quiz 1 – Answers
1) polymer, two, double
DNA is a POLYMER made up of TWO strands forming a DOUBLE helix
2)
a) The nucleus
b) 46 or 23 pairs
c) A short section of DNA that codes for a particular sequence of amino acids that are put together to make a specific protein
d) 20
3)
a) The genome of an organism is the entire genetic material of that organism
b) The human genome project was a project where scientists found all of the different genes in humans
4)
a) We can scan the DNA of individuals to find out whether they have a particular gene or genes that have an increased chance of developing certain diseases. If they do have the gene or genes, we can then give them advice on ways that they can reduce their chances of developing the disease or how to slow the onset of the disease
b) By knowing the genomes of individuals, we can make more informed decisions as to the most effective way to treat a particular individual with certain genes. This can be with respect to the type of drugs, the dosage, the type of treatment etc.
c) Tracing the migration patterns of humans over time
5) Any 2 from:

5) Any 2 from:
- Increased stress and worry. If you have been told that you are at an increased risk of developing a disease, you are likely to become more stressed/ anxious about the future and any symptoms of that disease. The increased stress/ anxiety could reduce your quality of life and may even increase your risk of developing other diseases.
- We may have to give our genomes to insurers or employers. Insurers may refuse to insure people with certain genes or charge very high premiums. Employers may refuse to employ people with certain genes because they won’t want to pay sick pay/ find cover whilst the employee is off work.
- It may lead to gene-ism, which is where individuals that have certain genetic disorders or certain genes may feel like they shouldn’t have children so that they do not pass on their faulty genes.
Questions
1) Fill in the gaps in the sentence below; the first letter of the first word is a p.
DNA is a ______ made up of ______ strands forming a ______ helix
2)
a) In what subcellular structure is DNA found in plant and animal cells?
b) The DNA can coil up to form chromosomes. How many chromosomes do humans have?
c) Give a definition of a gene.
d) How many different amino acids are there?
3)
a) What is the genome of an organism?
b) What is the human genome project?
4) One benefit of the human genome project is that we now have a better understanding of how a specific gene or a few genes cause or increase the likelihood of an individual developing certain diseases.
a) Explain how knowing this can be useful for individuals to reduce their chances of developing certain diseases.
b) Explain how knowing the genome of individuals can help with the medication and treatment given to individuals with certain genes.
c) In additional to the medical benefits, what is another benefit of the human genome project?
5) Give two drawbacks of scanning the DNA of individuals to see if they have an increased risk of developing certain diseases. Explain each of your drawbacks.
