In transgenics, expression of transgene in target tissue is determined by
1 enhancer
2 transgene
3 promoter
4 reporter
Explanation:
Exp: A reporter gene is a gene that is used in molecular biology and genetics to study the expression of other genes. It is typically a gene whose product is easy to detect or measure, such as fluorescent protein or an enzyme. Reporter genes are often fused to the gene of interest and their expression can serve as a marker for the activity of target gene.
