Concept explainers
(a)
To identify: The genes expressed in a specific type of brain cell.
Introduction:
A particular gene can be identified through its expression in a particular cell and its interaction with other genes. To study the gene expression, specific mRNAs corresponding to a gene of interest are to be identified and reverse transcribed to form cDNA. This sequence can be identified through RT-PCR, DNA microarray analysis, and RNA sequencing. To study a particular protein, multiple copies of the gene fragment encoding that protein are synthesized through polymerase chain reaction (PCR). These gene fragments are then inserted into the expression vector to synthesize a large quantity of proteins encoded by the gene in a process known as gene cloning.
(b)
To isolate: The neurotransmitter gene expressed in brain cells.
Introduction:
A particular gene can be identified through its expression in a particular cell and its interaction with other genes. To study the gene expression, specific mRNAs corresponding to a gene of interest are to be identified and reverse transcribed to form cDNA.

To study a particular protein, multiple copies of the gene fragment encoding that protein are synthesized through polymerase chain reaction (PCR). These gene fragments are then inserted into the expression vector to synthesize a large quantity of proteins encoded by the gene in a process known as gene cloning.
(c)
To produce: Multiple copies of the gene encoding for neurotransmitter protein.

- 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?
