Ventral Root of Spinal Nerve. The ventral root (motor root) of each spinal nerve consists of axons from motor neurons whose cell bodies are found within the gray matter of the spinal cord. A ventral root and a dorsal root unite to form a spinal nerve, which passes outward from the vertebral canal through an intravertebral foramen (bone opening). A posterior branch (posterior ramus) of each spinal nerve turns toward the posterior to innervate muscles and skin of the back.
Studies to date suggest that the planktonic-biofilm transition is a complex and highly regulated process. The results reviewed in this article indicate that the formation of biofilms serves as a new model system for the study of microbial development.tudies to date suggest that the planktonic-biofilm transition is a complex and highly regulated process.

Topic: Control of gene expression in bacteria: positive vs negative control and inducible vs repressible. Group: Isabela Alesna, Bo-Sung Kim, Midori Yoshino. Weâll be covering the âControl of gene expression in bacteriaâ: This happens through transcriptional control and operon control.Before we jump into the process, letâs define things first. In the control of gene expression, there are a few key players: the operon, promoter, operator, structural genes, regulatory gene, and regulatory protein.An operon is a group of bacterial structural genes and sequences that control transcription of those genes into a single mRNA.opic: Control of gene expression in bacteria: positive vs negative control and inducible vs repressible.
