Holothuria Atra Mitochondrial Genome Data: 15,788 Base Pairs and Codon Usage

15,788 base pairs comprise the complete mitochondrial genome of the sea cucumber Holothuria atra, sequenced and analyzed by Jinjin Wang. The data includes 13 protein-coding genes, 2 rRNAs, 22 tRNAs, 18 non-coding regions, and codon usage frequencies for 20 amino acids. The dataset was last updated on April 17, 2026, and supports genetic evolutionary research in the Kiribati region.

Use Cases

• Comparative evolutionary analysis based on shared mitochondrial sequences among 19 Holothuroidea species
• Codon usage bias studies based on the frequency data for 61 codons encoding 20 amino acids
• Phylogenetic tree construction based on the genetic relationship data indicating closest relation to Holothuria polii
• Secondary structure prediction for tRNA based on the 62-72 base pair length data and cloverleaf models

Strengths

• Complete mitochondrial genome sequence of 15,788 base pairs with detailed structural annotation
• Includes specific quantitative metrics: 59.2% A+T content, amino acid representation from 1.03% (Cys) to 16.58% (Leu)
• Comparative evolutionary analysis performed against 19 related species within the Holothuroidea class

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The dataset is very small at 46.5 KB, indicating limited scope
