🧬 Before we go deeper into bioinformatics, let’s revisit a core concept in molecular biology: The Central Dogma

DNA → Transcription → RNA → Translation → Protein

This describes how genetic information flows inside cells. DNA stores the instructions, RNA carries those instructions, and proteins perform most biological functions.

💡 Why is this important in bioinformatics?
Many datasets we analyze such as RNA-seq, gene expression profiles, and protein interaction networks are directly linked to this information flow.

🔬 It becomes even more interesting with RNA modifications like m6A and m5C. These chemical marks can influence RNA stability, localization, and translation without changing the DNA sequence. This regulatory layer is known as epitranscriptomics.

We will explore this exciting field together soon 🙂

🧬MOTIVATION MONDAY🧬

If you've ever stared at code that looks like hieroglyphics, or read the same paper paragraph five times without it clicking, this is for you.

The journey into bioinformatics isn't always smooth. There are days when the data doesn't make sense. Days when the papers feel like they're written in another language. Days when you wonder if you're cut out for this.
But here's the truth: struggling doesn't mean you're failing. It means you're learning.

Every bioinformatician, yes, even the ones whose work you admire, has been exactly where you are. Confused. Frustrated. Ready to close that laptop and walk away.

The difference? They kept going. And so can you.

At BioNexus Hub, we believe that learning is hard, but you don't have to do it alone. Whether you're transitioning from pharmacy, medicine, biology, or any other field, you belong in this space. Your unique perspective matters. Your effort matters.
You're doing better than you think. Keep going. We're here with you. 🧬✨

🧬 Fun Fact Friday!

Only about 1.5% of the human genome codes for proteins.
The rest plays important regulatory roles — and bioinformatics is helping us uncover them.

Spoiler: It’s NOT junk DNA 😉

🛠️ TOOL TUESDAY 🛠️

Today's Tool: BLAST 🔍

What it does:
BLAST (Basic Local Alignment Search Tool) compares your DNA or protein sequence against MILLIONS of sequences in databases to find matches.

Why every bioinformatician needs it:
✅ 100% FREE and web-based
✅ Results in SECONDS
✅ Essential for identifying unknown sequences
✅ Used by scientists worldwide

Real-world applications:
🦠 Identify unknown bacteria
🧬 Infer gene function based on similarity to known genes
💉 Support genomic surveillance and outbreak investigations
🔬 Compare sequences across species

Think of it as Google... but for biology!

Found a mystery sequence? BLAST it!
