Understanding Cell Structure
To grasp the principles of Karp cell and molecular biology, one must first understand the basic structure of cells. Cells are the fundamental units of life, and they come in various forms and functions. There are two primary types of cells: prokaryotic and eukaryotic.
Prokaryotic Cells
- Definition: Prokaryotic cells are simpler and smaller than eukaryotic cells. They lack a true nucleus and membrane-bound organelles.
- Examples: Bacteria and Archaea are the two main groups of prokaryotic organisms.
- Key Features:
- No nucleus; genetic material is located in a region called the nucleoid.
- Cell wall present in most species, providing structure and protection.
- Ribosomes present for protein synthesis.
Eukaryotic Cells
- Definition: Eukaryotic cells are larger and more complex. They contain a true nucleus and various membrane-bound organelles.
- Examples: Animal cells, plant cells, fungi, and protists.
- Key Features:
- True nucleus that houses DNA.
- Organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus.
- Cytoskeleton providing structural support.
Molecular Biology Fundamentals
Molecular biology delves deeper into the molecular components that make up cells, focusing primarily on DNA, RNA, proteins, and their interactions.
DNA and Gene Expression
- Structure of DNA: DNA (deoxyribonucleic acid) is a double helix made up of nucleotides, which consist of a sugar, phosphate group, and nitrogenous base.
- Gene Expression Process:
1. Transcription: The process of copying a segment of DNA into RNA.
2. Translation: The decoding of RNA to synthesize proteins.
- Regulation of Gene Expression: Important for cellular differentiation and response to external stimuli.
Proteins and Their Functions
- Protein Structure: Proteins are made of amino acids and have four levels of structure (primary, secondary, tertiary, and quaternary).
- Functions of Proteins:
- Enzymatic: Catalyze biochemical reactions.
- Structural: Provide support and shape to cells.
- Transport: Carry substances across membranes.

Biochemical Techniques
- Western Blotting: Used to detect specific proteins in a sample.
- PCR (Polymerase Chain Reaction): Amplifies DNA segments for analysis.
Genetic Engineering Techniques
- CRISPR-Cas9: A revolutionary gene-editing tool that allows for precise modifications in the genome.
- Transfection: The introduction of nucleic acids into cells to study gene function.
