Question

question 19 2.5 points mutations in dna sequences may occur during the process of. a transcription. b translation. c replication. d tumor suppression. e apoptosis. question 20 2.5 points dna mutations can. a be detrimental. b be beneficial. c have no effect. d all of the above. question 21 2.5 points radioactive man, a comic - book superhero, gained his abilities by falling into a vat of industrial toxic waste. is this a likely outcome? last saved 8:12:08 pm

Explanation:

• For Question 19: DNA mutations often occur during replication when errors happen in copying the DNA sequence. Transcription makes RNA from DNA, translation makes proteins from RNA, tumor - suppression and apoptosis are cell - regulatory processes not directly related to DNA mutation occurrence during normal processes.
• For Question 20: DNA mutations can be detrimental (e.g., causing genetic diseases), beneficial (e.g., providing evolutionary advantages), or have no effect (silent mutations).
• For Question 21: Industrial toxic waste can contain mutagens. Exposure to mutagens can cause DNA mutations, and in theory, could potentially lead to new or altered traits. However, the extreme and specific outcome of gaining super - human abilities as in a comic book is highly unlikely in real - world biology, but mutations can occur.

Answer:

Question 19: C. replication
Question 20: D. All of the above
Question 21: In real - world biology, highly unlikely; but DNA mutations can occur due to mutagens in toxic waste.
