V. KESIMPULAN DAN SARAN

5.1 Kesimpulan

Dari hasil penelitian dapat disimpulkan bahwa : 1. Promoter β-aktin ikan mas telah berhasil diisolasi dengan panjang 1,5 kbp dan yang digunakan dalam pembuatan konstruksi adalah 1,3 kbp. Pada sekuens yang diisolasi terdapat faktor transkripsi yang biasa dijumpai pada promoter β- aktin, yaitu boks TATA, motif CCAAT dan motif CArG CCAT 6 GG. 2. Promoter homolog memiliki efektivitas yang lebih tinggi daripada promoter heterolog pada transgenesis ikan mas.

5.2 Saran

Promoter β-aktin ikan mas sebaiknya digunakan dalam memproduksi ikan mas transgenik untuk tujuan akuakultur. 30 DAFTAR PUSTAKA Alimuddin. 2003.
