NH4+ is toxic to plants, inhibit dinitrogenase and also interfere energy metabolism by dissociating ATP formation  from ETC  in both mitochondria and chloroplasts. What will plant cells do to avoid this problem?

a) Plant cells avoid ammonium toxicity by rapidly converting the ammonium generated from nitrate assimilation or photorespiration into nitrate

b) Plant cells avoid ammonium toxicity by rapidly converting the ammonium generated from nitrate assimilation or photorespiration into amino acids

c) The pathway for this conversion involves the sequential actions of glutamine synthetase (GS) and glutamate synthase (GOGAT)

d) The pathway for this conversion involves the sequential actions of Aspartate aminotransferase (Asp-AT) and Asparagine synthetase (AS)

Q. A researcher is studying a novel gene involved in eye development in Drosophila. They isolate a mutant strain where a single nucleotide insertion has occurred in the first exon of this gene. When a heterozygous fly (one mutant allele, one wild-type allele) is observed, its eyes develop completely normally. Based on the provided principles of genetic mutations, which of the following statements best characterizes this mutation?
