Quiz: Introduction to Biological Databases

1. Which type of genomic disorder involves alterations ranging from single nucleotide changes to complex chromosomal reconfigurations?

2. What is a primary difference between genomic disorders and monogenic diseases?

Genomic disorders are always less severe than monogenic diseases.
Monogenic diseases are caused by mutations in a single gene, whereas genomic disorders can involve a wide range of genetic alterations.
Genomic disorders cannot be inherited.
Monogenic diseases do not involve DNA alterations.

3. What role do environmental factors play in the manifestation of genomic disorders?

They are solely responsible for the development of genomic disorders.
They do not influence genomic disorders in any significant way.
They can trigger or exacerbate the manifestation of diseases in individuals predisposed to certain conditions.
They can directly mutate genes responsible for genomic disorders.

4. Which type of mutation does not alter the amino acid sequence of a protein but can affect gene expression levels and protein synthesis efficiency?

5. What is the consequence of a nonsense mutation?

6. Which type of mutation can lead to the addition of a segment of DNA to the chromosome, potentially disrupting gene function?

7. What defines a germline mutation?

A mutation that occurs in somatic cells and affects only the individual.
A mutation that occurs in the reproductive cells and can be passed to offspring.
A mutation that cannot be inherited.
A mutation that affects mitochondrial DNA only.

8. What inheritance pattern requires two mutated gene copies for the associated phenotype to be expressed?

9. In the context of genetic variations, what is a common variant?

10. What is the significance of synonymous mutations?

They always result in a gain of function of the protein.
They change the amino acid sequence of proteins.
Despite not altering the amino acid sequence of a protein, they can affect gene expression levels and protein translation efficiency.
They are a type of mutation that eliminates the function of a protein.
