Determine whether the following statement is true or false: Because introns are largely genetic junk, they do not need to be rem
uysha [10]

Answer:

False

Explanation:

Introns need to be removed precisely because the reading frame will be shifted if removed even single nucleotide too many or leaving an intronic nucleotide in the spliced mRNA .

Extra amino acids will be inserted if large pieces of introns are left in the mature messenger RNA.

In both cases, aberrant protien will be produced if the RNA splicing is not precise, hence they are needed to be removed by precision.

Make a list of the potential benefits and harms that might arise from knowing your complete genome sequence.
MaRussiya [10]

Answer:

The benefits and harms of learning about my DNA are mostly in medical, personal, civil and criminal fields.

Explanation:

a) Pros: learning about my genome sequence could provide new information on the genetic basis of poorly understood diseases with the potential to provide new therapies, immediate benefits based on the current understanding of genetic and health. Being aware of elevated risks for known diseases could allow me to make proactive decisions about my health such as visiting the doctor frequently for more check ups, screening. Choosing one type of prescription drug over another based on my metabolism, changing my diet or exercise plan, informing reproductive decisions, moreover, I would personalize my health care precisely.

b) Cons: the potential harms are the privacy invation, database exposure , which could lead to serious implications for the criminal justice system, which generally seeks to increase the availability of DNA samples from the population. It would create genetic discrimination, meaning that would be harder to find jobs, contract insurance,  even though we have a Genetic Information Nondiscrimination Act.
