Introduction to Genetic Testing


The following questions are based on information provided in the ‘Introduction to Genetic Testing’ webinar. For each question select the correct answer. There is only one correct answer for each question.

1. DNA is our hereditary material, it is the carrier of our genetic information passed from parent to offspring. Which statement is true?

2. True or false? A nucleotide is made up of one base + one sugar + phosphate. Nucleotides join together (base pairs) and are arranged in two long strands that form a spiral called a double helix.

3. Which statement is true with regard to genes?

4. Which statement is true with regard to genetic mutations?

5. Which of the following statement is false with regard to genetic variations.

6. What is a single nucleotide polymorphism (SNP)?

7. Refer to your SNP guide and specifically the SNP PON1 192 Gln>Arg (A>G). Which statement is false with regard to this SNP?

8. Based on your understanding of complimentary alleles, when considering the SNP PON1 192 A>G, depending on what strand you are looking at this may also be referred to in the literature as PON1 192 T>C

9. A phenotype is genetic make-up of a cell, organism or individual, usually with reference to specific characteristics whereas a genotype is the composite of an organisms’ observable traits such as behaviour, development and physiological properties.

10. Which of the following are not inclusion criteria for a SNP to be included in the DNAlysis reports?
