DNA replication and protein synthesis are crucial biological processes. DNA replication occurs only in the nucleus prior to mitosis, involving the copying of DNA nucleotides for cell reproduction. In contrast, protein synthesis involves transcription and translation, occurring throughout a cell's life in the nucleus and cytoplasm. This process utilizes RNA (mRNA and tRNA) and builds proteins from amino acids. The main components include DNA, Uracil (instead of Thymine), and various nucleotides. Both processes are essential for cellular function and life.

Protein Synthesis DNA Replication • Happens only in the nucleus • DNA nucleotides only • Only happens prior to mitosis • Involves DNA • Needed for cell reproduction • A copy of the DNA is made • Happens in nucleus and cytoplasm • Involves RNA and DNA Nucleotides • Happens throughout the cells life
Translation Transcription • DNA is involved • Happens in the nucleus • Thymine is involved • Part of Protein Synthesis • mRNA is involved • Uracil is involved • Amino Acids are involved • tRNA is involved • Happens in the cytoplasm
