A type I functional response, occurs when a predator’s rate of prey consumption increases linearly with an increase in prey density until the predator is satiated.

The type II functional response, occurs when the number of prey consumed slows as prey population density increases. 

In a type III functional response, prey consumption is low when prey population density is low, consumption is rapid when prey population density is moderate, and prey consumption slows when prey population density is high.

During abortive Transcription, RNA Polymerase Remains Stationary and Pulls Downstream DNA into Itself

RNA polymerase produces and releases short RNA transcripts of 10 nucleotides (abortive synthesis) before escaping the promoter, entering the elongation phase, and synthesizing the proper transcript. It has long been unclear how the enzyme’s active site translocates along the DNA template during initial abortive cycles of transcription. Three general models were proposed:- “transient excursion”, “Inchworming”, “Scrunching”

Two osteoblast proteins responsible for osteoclast maturation: 

1. Receptor activator for nuclear factor κ-B ligand  

2. Macrophage colony-stimulating factor
