Protein Synthesis Quiz 3 (24-25)

Dark hair and skin are produced by the protein MC1R, which makes a brown substance called melanin.

Where do hair and skin cells obtain the MC1R protein from?

• The protein is made by RNA inside of the cells.

• The protein is obtained from food.

• The protein is made from glucose and oxygen.

• The protein is harvested from germs living near the hair and skin.

Chymosin is a protein produced inside the stomach cells of baby farm animals by the CYM gene.
What are the basic steps for how cells produce chymosin?

• The CYM gene makes RNA, which makes the chymosin protein.

• The CYM gene makes a lipid bubble that produces the chymosin protein.

• The CYM gene edits a basic protein to change it into chymosin.

• The CYM gene is reshaped into the chymosin protein.

A person's hair color phenotype is controlled by the MC1R gene. Normally, this gene produces a protein that gives hair a dark brown to black color.

Sarah and Mako have dark hair, but their friend Jay has red hair. What most likely explains why Jay does not have dark hair?

• Jay's MC1R allele does not produce a functional protein.

• Jay does not have the MC1R gene.

• Jay's MC1R allele is more similar to Sarah's than to Mako's.

• Jay dyed their hair red; it is not possible for hair to naturally be red.

Ricin is one of the world's most toxic poisons. Ricin works by turning off the ribosomes of the body's cells. This can be deadly because...

• ...the body will not be able to make proteins at all.

• ...the body will make less RNA.

• ...the body will make the wrong proteins.

• ...the body will make tRNA instead of mRNA.

Today, most cheese is manufactured using genetically modified germs. Cow DNA is inserted into the DNA of germs using recombinant DNA technology.

Which of the following will result from combining cow DNA with germs?

• The germs will not survive because they cannot use the cow DNA.

• The germs will produce cheese proteins from the cow DNA.

• The germs will attack and destroy cheese.

• The germs will grow up into cows.
