Concept explainers
To determine: The characteristics of the Initiator elements.
Introduction: The transcription is a process in which a particular segment of DNA is copied into RNA. The process is catalyzed by an RNA polymerase enzyme. It is the first step of DNA based gene expression.
To determine: The characteristics of the BREs.
Introduction: Translation is a process of protein biosynthesis. In this process, the genetic code carried by mRNA is decoded to produce the polypeptide chain. The process follows transcription in which the DNA sequence is copied into an mRNA.
To determine: The characteristics of the DPEs.
Introduction: The TATA box is a sequence of DNA. It is found in the core promoter region of eukaryotes. The homolog of TATA box is present in prokaryotes and is called Pribnow box.
To determine: The characteristics of the MTEs.
Introduction: A core promoter is the region of the proximal promoter that contains the transcription start sites. It is the minimal stretch of DNA sequence that is sufficient to initiate the process of transcription.

- Other than oil and alcohol, are there other liquids you could compare to water (that are liquid at room temperature)? How is water unique compared to these other liquids? What follow-up experiment would you like to do, and how would you relate it to your life?arrow_forwardSelection of Traits What adaptations do scavengers have for locating and feeding on prey? What adaptations do predators have for capturing and consuming prey?arrow_forwardCompetition Between Species What natural processes limit populations from growing too large? What are some resources organisms can compete over in their natural habitat?arrow_forward
- Species Interactions Explain how predators, prey and scavengers interact. Explain whether predators and scavengers are necessary or beneficial for an ecosystem.arrow_forwardmagine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters? Which of these are examples of active transport?arrow_forward
- What are Amyloid Fibrils? What biological functions are these known to perform?arrow_forwardHow do histamine and prostaglandins help in the mobilization of leukocytes to an injury site? What are chemotactic factors? How do they affect inflammation process?arrow_forwardCompare and contrast neutrophils and macrophages. Describe two ways they are different and two ways they are similar.arrow_forward
