Synovial joints, often referred to as joints, are composed of two or more bones with a gap between the opposite bone surfaces, connected only by the fibrous connective tissue membrane around them. The synovial joint is the main form of bone joint and has great mobility.
<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>

Answer:
Transcription factors
Explanation:
This is because Eukaryotic gene expression is regulated by transcription factors and RNA processing, which occur in the nucleus, and during protein translation, in the cytoplasm.
Transcription in eukaryotic cells is controlled by proteins . These proteins then bind to some specific regulatory sequences and try to control the activity of RNA polymerase. The Gene expression is regulate by transcriptional regulatory proteins . Also ,the packaging of DNA into chromatin and methylatiin indicate levels of complexity to the control of eukaryotic gene expression.
