Answer:
The reaction with adenine dideoxynucleotides will run furthest in the gel
Explanation:
In dideoxy sequencing (also known as Sanger sequencing), the DNA template is used to run four different reactions in which only one class of dideoxynucleotide (ddNTP) is added. These four different ddNTPs (i.e., ddATP, ddCTP, ddTTP or ddGTP) act as terminators during DNA synthesis. Moreover, the additional factors required for DNA synthesis including standard deoxynucleotides (dNTPs), DNA polymerase and site-specific primers are added in equal volumes to prepare these four different reactions. Thus, during electrophoresis, the sizes of the DNA bands will depend on the specific ddNTP used in each reaction. In this case, the reaction containing ddATP (capable of terminating DNA synthesis at the 5' end) will run furthest in the gel.
Answer:
Stifling applied to silk cocoons in order to kill the pupae, preventing the moths and allowing the silk during long periods of time
Explanation:
Answer:
With the inhibition of cyclic AMP phosphodiesterase in that cell, Kinase A will not be inactivated, so phosphorylase kinase will remain active.
Explanation:
Phosphodiesterase is an enzyme that has the function of hydrolyzing cAMP by converting it to AMP. As a result, a protein called kinase is inactivated and lipids break down in fat metabolizing cells. CAMP is a cellular messenger.
Cyclic AMP phosphodiesterase, in turn, is an enzyme that catalyzes the conversion of cyclic AMP into a different molecule. as a result, a molecule called kinase A is deactivated. However, if inhibition of cyclic phosphodiesterase AMP in a muscle cell stimulated by adrenaline, Kinase A will not be deactivated, so phosphorylase kinase will remain active.
Answer: It is supported by hypotheses, repeated tests and law from one or more fields of science.
Explanation:
In the context of science, a theory is a well-established explanation for scientific data. Theories typically cannot be proven, but they can become established if they are tested by several different scientific investigators.
Answer:
Both statements are true
Explanation:
Many small tree saplings are competing for sunlight on the forest floor because tree saplings in forest floors are often deprived of adequate light as a result of the shade created by bigger trees in the forest. <em>Hence, the saplings jostle for light in order to effectively carry out light-requiring physiological activities such as photosynthesis and chlorophyll synthesis.</em>
The West Nile virus a virus that <em>generally affects the central nervous systems of birds - the primary host. It is transmitted from one bird to another through contact and by a vector - the mosquito</em>. The virus is also capable of being contracted by humans where it causes fatal neurological disorders.
