Next-generation sequencing (NGS) or high-throughput sequencing (HTS) technologies have revolutionized the field of genomics and enable sequencing of a large number of biological molecules at once. Here are some of the types of biological molecules that can be sequenced using NGS:

1. DNA: The most common use of NGS is for DNA sequencing and analysis. Whole-genome sequencing, exome sequencing, and targeted sequencing are some of the applications where DNA is sequenced using NGS.

2. RNA: RNA sequencing (RNA-seq) is used to study gene expression and transcriptomics. RNA is reverse transcribed to cDNA, which is then sequenced using NGS technology.

3. ChIP-Seq: Chromatin immunoprecipitation sequencing (ChIP-seq) is used to map protein-DNA interactions, notably transcription factor binding sites across the genome.

4. Epigenetic: DNA methylation and histone modifications can also be analyzed using NGS-based techniques. Bisulfite sequencing, methylated DNA immunoprecipitation sequencing (MeDIP-seq), and ChIP-seq techniques can be used to investigate the epigenetic regulation of genes.

5. Metagenomics: NGS can be used for metagenomic analyses to study complex microbial communities present in different environments. Metagenomics can help to identify different microbial species and explore their functions.

6. Proteins: NGS-based methods such as phage display library sequencing and ribosome profiling can be used to identify protein interactions and study translation.

These are just a few examples of the types of biological molecules that can be sequenced using NGS. The versatility of this technology has paved the way for developing new applications and studying various aspects of biology in a more comprehensive way.
