Study Notes
Primary Role of DNA in Genetics
- DNA contains the genetic blueprint for the development, functioning, and reproduction of all living organisms.
- It carries the instructions needed to build proteins, which are vital for cellular functions.
mRNA Synthesis
- The synthesis of mRNA from a DNA template is known as transcription.
- During transcription, RNA polymerase enzyme reads the DNA sequence and creates a complementary RNA strand.
Molecule Responsible for Catalysis
- Enzymes, which are primarily proteins, catalyze biochemical reactions in cells by lowering activation energy.
- They are crucial for metabolic processes and cellular functions, significantly increasing the rate of reactions.
Structure Translating mRNA into Proteins
- Ribosomes are the cellular structures responsible for translating mRNA into proteins.
- They facilitate the assembly of amino acids in the sequence specified by the mRNA.
Function of Ribonucleic Acid (RNA)
- RNA plays several essential roles, primarily in protein synthesis and gene regulation.
- It serves as a messenger (mRNA), as well as a component of ribosomes (rRNA) and transport molecules (tRNA) that deliver amino acids during translation.
