Study Notes
DNA replication
- The process of creating a copy of DNA
- Catalyzed by an enzyme called DNA polymerase
- Necessary for cell division and growth
- Eukaryotic DNA has multiple origins of replication, speeding up the process.
- Results in two daughter DNA molecules, each with one old strand and one new strand.
Protein Synthesis
- The process of creating proteins from DNA.
- Requires transcription and translation.
Transcription
- The process of creating messenger RNA (mRNA) from DNA.
- Occurs in the nucleus.
- mRNA carries the genetic code from DNA to the ribosome.
Translation
- The process of synthesizing proteins from mRNA.
- Occurs in the ribosomes.
- Requires three types of RNA
- Messenger RNA (mRNA)
- Ribosomal RNA (rRNA)
- Transfer RNA (tRNA)
Summary
Transcription
- Definition: Copying DNA into mRNA
- Purpose: To transfer genetic information from DNA to a format that can be used for protein synthesis
- Products: mRNA
- Location: Nucleus
Translation
- Definition: Creating proteins from mRNA
- Purpose: To synthesize proteins
- Products: Proteins
- Location: Ribosomes
