1. DNA as the blueprint:
- The nucleus houses the DNA, which contains genes. Each gene holds the code for a specific protein.
- This code is in the form of a sequence of nucleotides (A, T, C, G).
2. Transcription: DNA to RNA:
- The first step is transcription, where a copy of the gene's DNA sequence is made in the form of messenger RNA (mRNA).
- This mRNA molecule carries the genetic information from the nucleus to the cytoplasm.
3. Translation: RNA to Protein:
- In the cytoplasm, the mRNA molecule binds to a ribosome.
- The ribosome reads the mRNA code and assembles amino acids in a specific order, following the instructions from the mRNA.
- This process is called translation, and it results in the formation of a protein.
Basic Event Reproduction:
* DNA Replication: The process where DNA is copied, ensuring that each daughter cell receives a complete set of genetic information. This happens before cell division.
* Cell Division: The process where one cell divides into two daughter cells. This can be either mitosis (for growth and repair) or meiosis (for sexual reproduction).
Key Points:
* The nucleus is the control center of the cell, but it doesn't directly make proteins.
* Ribosomes are the sites of protein synthesis.
* The information for protein synthesis is transferred from the nucleus to the cytoplasm in the form of mRNA.
