Answer:
Many see RNA editing as an important alternative to DNA editing using techniques such as CRISPR.
Explanation:
Answer:
The mutagen might alter the DNA sequence, thereby altering the accessibility to transcription factors and thus activate the expression of oncogenes involved in cell proliferation
Explanation:
The DNA molecule consists of two antiparallel strands of nucleotides that wind around each other. Each DNA strand is formed by a backbone containing sugar (deoxyribose) and phosphate groups. This arrangement allows for DNA replication and transcription (and consequently also protein synthesis) to occur. If a mutagen agent binds to DNA, this might modify its structure, thereby altering DNA replication and transcriptional activity.
