Spermatogenesis is regulated by a negative feedback control system in which follicle-stimulating hormone (FSH) stimulates the steps in sperm cell formation. What is the negative feedback signal associated with sperm cell production that inhibits pituitary formation of FSH?

#Unit 13. Methods in Biology

With the help of DNA fingerprinting which can be used to determine paternity. There are three babies (Baby A, Baby B and Baby C) in a maternity ward, and three sets of confused and worried parents. (Father and Mother #1 are a couple, as are Father and Mother #2, and Father and Mother #3.) 

You do each PCR reaction on chromosome 15 and load each one into a separate well of an agarose gel, and then run the gel.

 

 which number of repeats did Baby C inherit from his mother?

#Unit 3. Fundamental Processes

Transcription of eukaryotic genes can be repressed in various ways. These include the four mechanisms

1. Competition	a-Repression is caused by recruiting histone modifiers that alter nucleosomes in ways that inhibit transcript
2. Inhibition	b-A repressor binds to a site on DNA beside an activator and interacts with that activator, occluding its activating region
3. Direct repression	c-By binding to a site on DNA that overlaps the binding site of an activator, a repressor can inhibit binding of the activator to a gene and thus block activation of that gene.
4. Indirect repression	d-A repressor binds to a site upstream of a gene and, by interacting with the transcriptional machinery at the promoter in some specific way, inhibits transcription initiation.
