The Journey of Dendrobium catenatum Genome Assembly

The NCBI WGS project follows a meticulous process to ensure the accuracy and completeness of the Dendrobium catenatum genome assembly:

1. DNA Extraction: The process begins with extracting high-quality DNA from Dendrobium catenatum tissue. This is a critical step, as the quality of the DNA directly impacts the accuracy of the sequencing results.

2. DNA Fragmentation: The extracted DNA is then broken down into smaller fragments. These fragments are typically a few hundred to a few thousand base pairs in length.

3. Sequencing: The DNA fragments are sequenced using high-throughput sequencing technologies. These technologies can generate millions or even billions of DNA sequences in a single run.

4. Assembly: The sequenced fragments are then assembled into a complete genome sequence using sophisticated computational algorithms. This is a challenging process, as the genome may contain repetitive sequences that can make it difficult to determine the correct order of the fragments.

5. Annotation: Once the genome is assembled, it is annotated to identify the genes and other functional elements that it contains. This involves comparing the genome sequence to known genes and proteins from other organisms.

6. Validation: The assembled genome is validated to ensure its accuracy and completeness. This involves comparing the genome sequence to other sources of information, such as genetic maps and expressed sequence tags (ESTs).
