The endoplasmic reticulum transports proteins around the cell, so when the ribosome makes the protein, the endoplasmic reticulum transports it to the Golgi body for further processing.
Answer:
d. allow for coordinated gene expression of related genes on one mRNA controlled by one promoter.
Explanation:
An operon is a group of functionally-related genes that share the same promoter region and the same operator which interacts with specific repressors or activators, and they are transcribed as a unit. This transcriptional unit (operon) is present in prokaryotic organisms (i.e., bacteria and archaea) but absent in eukaryotes. In an operon, each structural gene is known as a cistron, and they are transcribed together as a polycistronic primary messenger RNA (mRNA).
Answer:
The bacteria are activated through exposure to acids in the gut of the Dermacentor tick. The bacteria are activated after the tick feeds on a host for several hours. The bacteria are activated when the tick reaches its adult stage.
