The sequence of Nucleotides in a DNA molecule determine the protein that will be produced. Nucleotides are the basic structural unit of DNA.
Answer:
All errors described will result in a negative result
Explanation:
The enzyme-linked immunosorbent assay (ELISA), is a test used to detect and measure antibodies, antigens and proteins in the blood. An ELISA test uses antibodies and/or antigens that are coupled to an easily-assayed enzyme, thereby this approach combines antibody specificity with the sensitivity of simple enzyme assays. ELISA test involves an antibody or antigen that reacts to form an antigen-antibody complex, where such reaction is interpreted as a positive result. The negative results are evidenced by the lack of reaction, which may be caused by some error during the chain of reactions in the ELISA test: antigen >> primary antibody (reaction) >> functional secondary antibody (reaction) >> conjugated enzyme (reaction) >> functional substrate.
Answer:
The correct sequence is 21543.
Explanation:
The procedure by which the signaling molecules known as neurotransmitters are discharged by the neuron's axon terminal and combines and reacts with the receptors present on the dendrites of another neuron or postsynaptic neuron is termed as neurotransmission.
The following are the steps followed in the process of neurotransmission:
a. Exocytosis of neurotransmitter gets stimulated by calcium.
b. The diffusion of neurotransmitter takes place across the synaptic cleft.
c. The binding of neurotransmitters takes place with the receptor.
d. After the binding opening of ion channels takes place.
e. The permeability of the postsynaptic membrane gets changed.
Answer:
C. Northwestern side of a low-pressure system
Explanation:
I just did the test ^^
Answer:
elongation rate of strain of S.cerevisiae during transcription.
wild-type and experimental strain not treated with soultion of amanitin will be the control group. The elongation rate of mRNA of this group must be observed.
Explanation:
Dependent variable is one whose value depends on another value. Here effect of presence of mRNA polymerase enzyme and inhibtor on elnogatino rate of mRNA is being observed. So elongation rate is the dependent variable
Control group is one where independent variable whose effect is being observed can't influence the results. In experiment 2, the effect of inhibitor is being observed. So the control group must not have that inhibitor. Other conditions must remain same for experimentan and control group.
