Concept explainers
To explain: Whether the same types of gene control operate in bacterial cells and eukaryotic cells.
Concept introduction: Gene is the fundamental unit of heredity, which is composed of DNA. Each gene specifies a particular protein. For this, the genes are converted into a useful product through the process of gene expression. Gene expression involves the conversion of DNA into RNA through the process of transcription, and this RNA will be converted into proteins through the process of translation. Operons are the set of genes containing a promoter and one or more operators that help to control the transcription process. A type of operon called lac operon, which can occur in the bacteria, is used to

- magine 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?
