Answer:

Bacteria do not possess the tendency to withdraw sequences of introns from a gene, thus, if the gene for the human growth hormone were transcribed, it would translate into a non-functional protein.  

When the expression of a gene takes place in eukaryotes, the budding mRNA comprising introns are removed consequently at the time of post-translational processing to produce mature mRNA. Also, the human growth hormone is produced by the pituitary gland in the form of a pre-hormone comprising a leader peptide of about 20 amino acids in length, which need to get removed post-translationally to produce a mature functional protein.  

Bacteria do not possess the biochemical machinery either to effectively withdraw the leader peptide after translation or to splice out the introns. Thus, when an unchanged human growth hormone is cloned, the bacteria cannot produce the functional human growth hormone.

<em>The preclinical trial of therapy against Alzheimer’s disease (AD) is an essential and complex step. It functions as a bridge between candidate discovery and clinical development since it constantly provides us with new information on pieces of the complex AD puzzle. Analysis of this information is likely to reveal patterns of pharmacological interactions instead of the single potential drug target. A group of well-trained, knowledgeable medicinal biochemists in Alzheimacy with decades of experience in preclinical research are willing to work with leaders and scientists from academia, pharmaceutical and biotechnology companies around the world to further develop more promising and stringent therapeutics for AD.</em>
