🌟 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) 🧬
- 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
- Matches amino acids with mRNA codons during translation
- Forms a structural part of ribosomes, aiding in protein synthesis
