The case studies on the evolution of marine arthropods through de novo genome assemblies and analyses
학위논문 (박사) -- 서울대학교 대학원 : 자연과학대학 생명과학부, 2020. 8. 김원. The de novo genome assembly has become an essential approach for studying non-model organisms since the post-genome era arrived. The reported cases of de novo genome assemblies of non-model arthropods have increased dramatically in recent days. The...
