🌟 Introduction to RNA
- What is RNA?: Definition of RNA (Ribonucleic Acid) 📜
- Role in Biology: Essential for gene expression, protein synthesis, and cellular communication 🌱
- Importance: RNA as a fundamental molecule for life on Earth 🌍
🧱 Structure of RNA
- Single-Stranded 🔄: Unlike DNA, RNA is usually single-stranded
- Nucleotides in RNA 🧩:
- Adenine (A) 🧬
- Uracil (U) 🧬 (replaces Thymine in DNA)
- Guanine (G) 🧬
- Cytosine (C) 🧬
- Phosphodiester Bonds 🔗: Link nucleotides together in a chain
- Structural Differences from DNA 🧬:
- RNA is single-stranded, while DNA is double-stranded
- RNA contains uracil instead of thymine
🧬 Types of RNA and Their Functions
- Messenger RNA (mRNA) 📨:
- Carries genetic instructions from DNA for protein synthesis
- Transfer RNA (tRNA) 🧬:
- Matches amino acids with mRNA codons during translation
- Ribosomal RNA (rRNA) 🔬:
- Forms a structural part of ribosomes, aiding in protein synthesis
