Question

question 8
what is a reporter gene?
the starting gene that restriction enzymes cut to add the new dna
the coding sequence to be placed into the bacterial plasmid
the spot were the bacterial plasmid is glued back together
a reporter gene is pasted into a genome with genes researchers would
question 9
what did scientist discover about rnai
rnai is a way to treat genetic diseases through inactive viruses.
rnai uses recombined bacteria to help fight diseases

Explanation:

(Question 8):
Reporter genes are marker genes inserted alongside target genes in genetic engineering; they produce a detectable signal (like fluorescence) to confirm the target gene is being expressed, which matches this option. The other options describe restriction enzyme cut sites, insert DNA sequences, and plasmid ligation sites, not reporter genes.

(Question 9):
RNA interference (RNAi) is a cellular mechanism that silences gene expression. Researchers have developed methods to deliver RNAi molecules using inactive (non-replicating) viruses to target disease-causing genes, making this the correct discovery. The other option incorrectly links RNAi to recombined bacteria, which is associated with other biotechnologies like plasmid-based gene delivery, not RNAi.
