The laboratories have initiated Phase 1 clinical trials for the use of human pluripotent embryonic stem cells to treat paralyzed patients following spinal cord injury. The first step is to estimate the risks and tolerance of cell transplantation in a man. The fate of stem cells (multipotent or pluripotent) in the body is still poorly understood, and it is not excluded that uncontrolled cell multiplications occur, leading to the appearance of teratomas (tumor developed from pluripotent cells).
Advantages are:
* The safety of the cells also seems to be proven (in short term)
* Rats transplanted seven days after the injury had benefited from reactivation of myelinization of neurons by oligodendrocytes, attenuation of motor neuron loss and improvement of limb motor function.
The disadvantages are:
* Constraints of the ethical and religious order, it is necessary the consent and the approval of the donor and the recipient for the transplant to take place.
* The development of the technique is still new, there is a chance that side effects of the transplant appear years after the operation.
A Ribosome is not a membrane bound organelles
Answer:
Explanation:
Hardy Weinberg law is represented by the equation below
p² + 2pq + q² and states that the frequency of alleles and genotypes will remain constant in the absence of evolutionary disturbances such mutation, natural selection, migration and the population is large and mating is random.
where p² represent the frequency of homozygous dominant geotypes and 2pq represent the frequency of heterozygous genotypes and q² represent the frequency of the homozygous genotypes
p is the frequency of the dominant alleles and q is the frequency of the recessive alleles.
given
q² = 25% = 0.25
q = √0.25 = 0.5
