Figure 1From: Optimization of codon composition and regulatory elements for expression of human insulin like growth factor-1 in transgenic chloroplasts and evaluation of structural identity and functionNucleotide sequence of IGF-1 genes. A) Nucleotide sequence of the native IGF-1n gene. B) Nucleotide sequence of the synthetic IGF-1s gene optimized for chloroplast expression. Red letters show nucleotides that were modified in the IGF-1s gene.Back to article page
