Answer:
The number of artificial mRNA 3 nucleotide codons that would be possible is eight (8), which are: AAA, AAG, AGA, GAA, AGG, GGA, GAG, and GGG.
Explanation:
The arrangement of the nucleotides within the codon permit repetition. The adenosine triphosphate is designated as A, while the guanosine triphosphate as G. The possible number of codons that can be formed from this two available nucleotides is 2 to the power of 3 = 8
These codons are: AAA, AAG, AGA, GAA, AGG, GGA, GAG, and GGG.
Answer:
The virus will transfer the DNA encoding cholera toxin to the next bacteria it infects, which will make that bacteria cholera-causing.
Explanation:
The process described in this question is a kind of gene transfer in bacteria called TRANSDUCTION. Transduction is the transfer of fragments of DNA from one bacterium to another via a virus called bacteriophage.
As stated in this question, the virus (bacteriophage) infects a cholera-causing bacterium. The bacteriophage moves from lysogenic cycle to lytic cycle and includes some pieces of the bacterial DNA, which encodes information for making the cholera toxin, in its own genome.
This means that the cholera-making toxin DNA is now a part of the virus's genome and hence, will transfer it to the next bacteria it infects in a process called TRANSDUCTION. This will make that bacteria a cholera causing bacteria.
Answer:
Phase III.
Explanation:
Clinical research includes the different steps to test the particular drugs and its use for the medical treatment. Clinical research is divided into four main phases.
The phase III of the clinical research includes the double blinded study and its clinical trial on the patients. This phase determines the drug safety and efficacy. The therapeutic effect of the drug is tested directly in phase III of the clinical trial.
Thus, the answer is phase III.
Answer:
Explanation:
motor neuron is the neuron that have it's connection to a muscle at the neuromuscular junction,. At his junction, a synaptic cleft that has a motor end plate is formed by the activity of the terminal called "synaptic terminal". Diffusion of the acetylcholine across the synaptic cleft then occur which result to the sarcolemma been depolarized, as a result of the depolarization there is a output of Ca2+ and muscle contraction
The effect that botox have on the neuromuscular junction and its function is that there is interaction between Botox and neural transmission which obstruct the acetylcholine to be released, which result to paralysis of muscle.
