Successful follicular development depends on communication among the oocyte, granulosa cells, theca cells, and ovarian stroma. Which interaction do you consider most critical for allowing a recruited follicle to become dominant, and why? Trace how disruption of that interaction could affect androgen production, estradiol synthesis, FSH responsiveness, oocyte competence, and eventual ovulation.

A paired-end read has FLAG = 147. Using bit values 1 = paired, 2 = proper pair, 16 = reverse strand, 128 = second in pair (Read 2), which combination correctly explains FLAG 147, and what does it represent biologically? A) 1 + 2 + 16 + 128 = 147: a properly paired, reverse-strand Read 2 B) 1 + 4 + 16 + 128 = 149, which does not equal 147 C) 2 + 16 + 64 + 65 = 147: an unmapped Read 1 D) 1 + 2 + 32 + 64 = 99, which is a different FLAG value entirely

A STAR RNA-seq Log.final.out report shows: Uniquely mapped reads % = 42%, Unmapped (too short) % = 35%, Multi-mapping % = 3%. What is the most likely interpretation and appropriate first troubleshooting step? A) This is excellent-quality data requiring no further action B) The low unique-mapping rate combined with a high “too short” unmapped percentage suggests possible adapter contamination or an incorrect/mismatched reference genome; the appropriate first step is to re-check FastQC adapter content and confirm the correct reference/species were used C) The high multi-mapping rate is the primary cause of the poor result D) The library was simply over-sequenced and should be down-sampled
