What is the difference between transcription and translation?
Transcription is the process of copying DNA into RNA, while translation is the process of using RNA to make proteins.
Can mutations be harmful, beneficial, or neutral?
Yes, mutations can be harmful, beneficial, and neutral.
What type of bond holds the two strands of DNA together?
