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.
