Machine Learning dalam Biologi dan Bioinformatika: Masa Depan Analisis Data Hayati

Pendahuluan: Revolusi Digital di Dunia Biologi

Beberapa dekade terakhir, biologi telah bertransformasi dari ilmu observasional menjadi ilmu berbasis data. Proyek Human Genome Project memicu ledakan data biologis—dari sekuens DNA, ekspresi RNA, hingga citra mikroskop beresolusi tinggi. Volume data yang dihasilkan setiap hari menuntut pendekatan baru dalam analisis.

Di sinilah machine learning (ML) berperan. Melalui algoritma cerdas yang belajar dari data, peneliti kini mampu mengidentifikasi pola biologis yang sebelumnya tersembunyi, mempercepat penemuan obat, memahami fungsi gen, serta memprediksi interaksi antarprotein atau mikroba.

Apa Itu Machine Learning dalam Konteks Biologi?

Secara umum, machine learning adalah cabang dari kecerdasan buatan (AI) yang memungkinkan komputer belajar dari data tanpa diprogram secara eksplisit.
Dalam biologi dan bioinformatika, ML digunakan untuk:

• Kinerja lebih baik dibanding WSL1 (karena menggunakan kernel Linux nyata).

• Kompatibilitas lebih tinggi untuk aplikasi Linux, Docker, tools pengembangan.

• Integrasi file system antara Windows dan Linux → Anda bisa mengakses file Windows dari Linux dan sebaliknya dengan mudah.

Karena kelebihannya, banyak pengembang menggunakan WSL2 untuk workflow pengembangan yang fleksibel tanpa harus dual-boot atau menjalankan VM besar.

Apa Itu Metagenomik? Bedanya Amplicon dan Shotgun, serta Contohnya di Dunia Pertanian Organik

Pendahuluan: Apa itu Metagenomik?

Metagenomik secara umum adalah studi tentang seluruh materi genetik yang ditemukan dalam suatu komunitas mikroba di lingkungan tertentu, tanpa harus melakukan isolasi dan kultur mikroorganisme satu-per-satu.

Dengan kata lain, daripada menumbuhkan bakteri di cawan dan kemudian meng­urutkan genomnya, kita melakukan ekstraksi DNA atau RNA dari seluruh komunitas mikroba (misalnya tanah, air, daun tumbuhan, usus) dan kemudian melakukan sequencing untuk mengetahui “siapa hadir” dan/atau “apa yang bisa dilakukan (fungsi)” oleh komunitas tersebut.

Metagenomik memungkinkan kita menggali ekosistem mikroba yang sebelumnya sulit atau tidak bisa dikultur — dan membuka peluang besar dalam berbagai bidang seperti ekologi mikroba, agrikultur, bioteknologi, kedokteran, lingkungan.

Namun, dalam praktiknya ada beberapa pendekatan berbeda — dua yang paling umum adalah amplicon metagenomics dan shotgun metagenomics. Kedua pendekatan ini memiliki kelebihan dan kelemahan, serta cocok untuk jenis pertanyaan riset yang berbeda.

Sejarah DNA Sekuensing

Pendahuluan

DNA (asam deoksiribonukleat) adalah molekul genetik yang menyimpan informasi biologis dari makhluk hidup. Mengetahui secara tepat urutan basa DNA (A, T, G, C) sangat penting dalam genetika, biologi molekuler, evolusi, diagnosis penyakit, penelitian genomik, dan aplikasi bioteknologi lainnya. Namun, proses penentuan urutan DNA (sekuensing) tidaklah mudah: metode‐metode awal sangat lambat, labor intensif, dan mahal. Seiring waktu, teknologi berkembang dari metode generasi pertama (low throughput) ke generasi kedua (high throughput, pendek) dan generasi ketiga (single molecule, long reads). Artikel ini menelusuri perjalanan teknologi tersebut.

Awal Mula: Menjelajah DNA sebelum “sekuensing modern”

Sebelum teknologi sekuensing modern muncul, para peneliti mempelajari sifat kimia DNA, memisahkan untai, dan memetakan fragmen berdasarkan teknik kimia dan fisika. Namun penentuan urutan basa secara langsung belum mungkin.

What Is Next-Generation Sequencing (NGS) and Why It Matters in Modern Science

 Introduction

In the past, sequencing a single human genome could take years and cost millions of dollars. Today, thanks to Next-Generation Sequencing (NGS), scientists can decode entire genomes within hours at a fraction of the cost. This powerful technology has transformed biology, medicine, agriculture, and even environmental research.

What Is NGS?

Next-Generation Sequencing (NGS) refers to advanced DNA sequencing technologies that allow millions of DNA fragments to be read simultaneously. Unlike traditional Sanger sequencing, which processes one fragment at a time, NGS performs massively parallel sequencing, producing huge amounts of data quickly and accurately.

How Does NGS Work?

Understanding the Basics of Molecular Docking

 

Understanding the Basics of Molecular Docking

Molecular docking is a computational technique used to predict how a small molecule (ligand) interacts with a larger biological target such as a protein, enzyme, or nucleic acid. It plays a crucial role in drug discovery, allowing scientists to explore how potential drug candidates might bind to their target receptors and exert biological effects.

1. What Is Molecular Docking?

Molecular docking simulates the interaction between two molecules to predict the most stable binding pose and estimate the binding affinity. The process involves two main components:

• Receptor (Target): The biological molecule, typically a protein, responsible for a physiological function.

• Ligand: A small molecule that can bind to the receptor to modulate its activity.

The docking algorithm searches for the optimal orientation of the ligand within the receptor's binding site and scores each possible configuration based on the predicted strength of interaction.

Sleep Loss and College Student Performance

The college experience is of great value in providing emerging adults with a structured environment in which they can gain the knowledge, skills, and independence to chart their own path, become successfully employed, and contribute to society. However, this experience comes at great cost given rising tuition fees and ballooning student debt, and thus, it is vital that the college years be as efficacious as possible. A potential obstacle to maximizing success in college is the high prevalence of sleep loss and irregular sleep schedules among college students.

CRISPR/Cas Systems and Their Application for Genome Editing

            1.     Introduction

CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is an array of short repeated sequences separated by spacers with unique sequences. CRISPR can be found on both chromosomal and plasmid DNA of bacteria. The spacers are often derived from nucleic acid of viruses and plasmids, and are used as recognition elements to find matching virus genomes and destroy them. These sequences play a key role in a bacterial immune system, and form the basis of a genome editing technology known as CRISPR/Cas9 which allows permanent modification of genes within organisms.

Compare and Contrast Gene Regulation in Bacteria and Human

To understand how gene regulation is controlled in both prokaryotic (Bacteria) and eukaryotic (Human) cells, we have to understand how a gene codes a functional protein in a cell. The process occurs in slightly different manners. 

Prokaryotic organisms (i.e. Bacteria) are single-cell organisms which lack a nuclear membrane, and their DNA floats freely in the cell cytoplasm. The transcription and translation processes occur simultaneously in the cytoplasm. When the resulting protein is not required, the transcription process is stopped. As a result, the fundamental method to control what type of protein and how much protein is expressed in a prokaryotic cell is the regulation of DNA transcription. When more protein is needed, more transcription occurs. Therefore, in the prokaryotic cell, the control of gene regulation is mostly at the transcriptional level.

PROTEIN ASAM AMINO LEVO

Mari kita amati dengan seksama mengapa skenario evolusionis tentang pembentukan protein mustahil terjadi.

Rangkaian yang benar dari asam-asam amino yang tepat saja tidaklah cukup untuk pembentukan molekul protein. Di samping itu, keduapuluh jenis asam amino yang membentuk protein harus merupakan asam amino Levo. Asam amino terdiri dari dua jenis yang berbeda, yaitu "levo" (kiri) dan "dextro" (kanan). Perbedaan di antara keduanya adalah simetri cermin antara struktur tiga dimensi mereka, yang serupa dengan simetri tangan kiri dan kanan manusia.
