6. Replication
Occurs in the nucleus during S phase of cell cycle.

7. Replication Occurs in the nucleus during S phase of cell cycle.
Why? So that each new cell can have an identical copy after division.

8. Protein synthesis
Transcription: DNA polymerase unzips and reads one side of DNA strand. mRNA is formed. (single stranded)

9. Protein synthesis
Transcription: DNA polymerase unzips and reads one side of DNA strand. mRNA is formed. (single stranded)
Triplet: 3 DNA bases in a row.

10. Protein synthesis
Transcription: DNA polymerase unzips and reads one side of DNA strand. mRNA is formed. (single stranded)
Triplet: 3 DNA bases in a row.
RNA: single stranded mirror image of DNA

11. Protein synthesis
Transcription: DNA polymerase unzips and reads one side of DNA strand. mRNA is formed. (single stranded)
Triplet: 3 DNA bases in a row.
