Chapter 3, Problem L3.1g
Write a single sentence, using no more than 25 words, to summarize each of the following cellular processes:
DNA synthesis
Verified step by step guidance1
Understand that DNA synthesis is the process of creating a new DNA strand during cell replication, ensuring genetic information is accurately copied.
Recognize that DNA synthesis occurs during the S phase of the cell cycle, involving enzymes like DNA polymerase and helicase.
Learn that helicase unwinds the DNA double helix, creating a replication fork for the synthesis of new complementary strands.
Explore how DNA polymerase adds nucleotides to the growing strand, following base-pairing rules (A-T and G-C) to ensure accurate replication.
Summarize the process in a concise sentence: 'DNA synthesis is the enzymatic replication of DNA, ensuring genetic fidelity during cell division.'

Textbook Question
A popular science fiction program once had an episode that featured an 'intron virus' that 'turned on' the introns in the genes, causing the synthesis of abnormal proteins. The episode may have been entertaining, but its premise had a large flaw about the nature of introns. What was the flaw?
