📖 1. Genes, DNA and RNA

🔑 Key Concepts & Definitions

• DNA : DNA is the nuclear support of inherited traits made of nucleotide sequences.
• Gene : A gene is a specific sequence of nucleotides located on the DNA molecule.
• RNA : RNA is an acid made of ribonucleotides, with ribose as its sugar.
• Uracil : Uracil is a base that characterizes RNA molecules among the nucleic acids.

📝 Essential Points

• DNA is located in the nucleus.
• Genetic traits are encoded in genes carried by the DNA molecule.
• A ribonucleotide contains ribose, a five-carbon sugar.
• RNA is a short single-stranded molecule with ribonucleotides (A, G, C, and U).

💡 Memory Hook

Think DNA stays in the nucleus; RNA is the single-strand message builder using U instead of T.

📖 2. Transcription and mRNA synthesis

🔑 Key Concepts & Definitions

• Transcription : Transcription is the nuclear step that biosynthesizes mRNA from a DNA template strand.
• mRNA : mRNA is the messenger RNA that transfers genetic information from the nucleus to ribosome sites.
• RNA polymerase : RNA polymerase is the enzyme that synthesizes mRNA during transcription.
