“Molecular Biology of the Cell” by Bruce Alberts,



1. Structure and Function of Biological Macromolecules



DNA: The structure of DNA is a double helix made of nucleotides. It stores
genetic information, and its replication is a crucial process in cell division.



Proteins: Proteins are made of amino acids and perform a variety of
functions, including enzymatic activity, structural support, and signal
transmission.



RNA: RNA is involved in the transcription process (copying DNA into mRNA)
and translation (mRNA to protein synthesis) in cells.




2. The Cell Cycle and Cell Division



Interphase: Comprises the G1, S, and G2 phases. During the S phase, DNA
replication occurs.



Mitosis: The process by which a cell divides its chromosomes into two
daughter cells. This process is tightly regulated to ensure accurate genetic
material distribution.



Meiosis: A specialized type of division that reduces chromosome numbers by
half, leading to the formation of gametes (sperm and egg cells).




3. Protein Synthesis: Transcription and Translation
