Research Hypothesis - Explorable
A research hypothesis is the statement created by researchers when ..
Use the examples and the writing tips described below, and in the powerpoints linked to this page, to help you to write your own research question or for writing research as specific as some cases, you may make two or more research questions to cover a complex example, if you are studying the effects of sleep on reflexes, you might formulate the following research question: what are the effects of sleep on reflexes? The researcher randomly assigns participants to different conditions, measures the variables of interest and tries to control for confounding variables. Scientists must generate a realistic and testable hypothesis around which they can build the might be a question, a statement or an ‘if/or’ statement.
The precursor to a hypothesis is a research ..
The signal hypothesis, which describes how secretory and membrane proteins are targeted to the endoplasmic reticulum, was proposed in 1971 by Günter Blobel and David Sabatini and demonstrated by Blobel and Bernhard Dobberstein in 1975. Subsequent research identified the key components of the membrane insertion and translocation machinery, including the signal recognition particle (SRP), the SRP receptor and the protein‐conducting channel. Ultimately, the signal hypothesis was shown to be true for not only eukaryotes but also prokaryotes. Most importantly, the concept of signal‐mediated targeting was expanded into a general hypothesis of cellular topogenesis that helps to explain how proteins are distributed to their correct locations within the cell following their synthesis in the cytoplasm.
