28.2 Base Pairing in DNA: The Watson–Crick Model
•
•
• Replication—the process by which identical copies of DNA are made so that information can be preserved and handed down to off spring
• Transcription—the process by which the genetic messages are read and carried out of the cell nucleus to ribosomes, where protein synthesis occurs
• Translation—the process by which the genetic messages are decoded and used to synthesize proteins
28.3 Replication of DNA
• ′ → ′
• ′ ′
• ′ ′•• ′ ′
28.4 Transcription of DNA
•
• uracil rather than thymine
• All RNA molecules are much smaller than DNA, and all remain single stranded rather than double-stranded.
