Study Notes
Differences Between DNA in Prokaryotes and Eukaryotes
- Prokaryotic DNA is circular and typically located in a region called the nucleoid, while eukaryotic DNA is linear and organized into chromosomes within a membrane-bound nucleus.
- Prokaryotes usually have a single, haploid chromosome; eukaryotes have multiple, diploid chromosomes.
- Prokaryotic cells often have plasmids, small circular DNA molecules, whereas eukaryotic cells have more complex packaging, including histone proteins.
Basic Unit of DNA
- The basic unit of DNA is the nucleotide, which consists of a phosphate group, a sugar (deoxyribose), and a nitrogenous base.
- There are four types of nitrogenous bases in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).
Focus of Molecular Medicine
- Molecular medicine focuses on understanding the molecular and genetic basis of diseases to develop targeted therapies.
- It aims to incorporate molecular biology and genetics into clinical practice to enhance diagnosis, treatment, and prevention of diseases.
Base Pairing in DNA
- Base pairing in DNA occurs between complementary nitrogenous bases: adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).
- These pairings are essential for the double helix structure of DNA and for accurate DNA replication and transcription.
Overview of Learning Outcome
- The learning outcome summarizes key concepts related to DNA structure and function, highlighting the differences between prokaryotic and eukaryotic DNA, the significance of molecular medicine, and the fundamental principles of base pairing.
- It serves as a foundation for understanding genetic information transmission and its implications in health and disease.
