The BLAST program begins with a particular genetic sequence anda. translates it into an amino acid sequence.b. determines if it contains one or more genes.c. identifies homologs within a database.d. does all of the above.
1a) Why is it possible for you to study the eye colour gene by extracting cheek cells?
a. Because the nucleus of every cell in the human body contains the same genetic information.
b. Because the cheek cells are located near the cells of the eye and so they are able to exchange DNA.
c. Because all genes in the human body are expressed at all times so it is easy to study them.
d. All of the above are possible explanations.
1b) What is the purpose of heating the sample to 75°C following addition of the 0.2M NaOH solution?
a. To denature the histone proteins that are keeping the DNA tightly coiled.
b. To ensure that all the DNA is removed from the swab in preparation for PCR.
c. To breakdown the cheek cell membrane to release the DNA from the cell.
d. It breaks down the circular DNA down into linear fragments so that they will be easier to visualize.i
Describe the mechanistic steps through which gene therapy might be used to cure a disease that is caused by mutations in "Gene D". A potential patient is reluctant to undergo this treatment, because they remember hearing about adverse incidents from gene therapy studies conducted decades ago. What relevant details might you tell them, in order to inform them on this topic?.
