I’m studying for my Biology class and need an explanation.
Part 1: Post a Response
This week is all about our DNA and gene expression. The complete set of all DNA in a cell is called the genome. The complete set of all the mRNA in a cell is called the transcriptome. Read the following article about the transcriptome found at: https://www.genome.gov/13014330/transcriptome-fact-sheet/, then address the following:
- Explain how the transcriptome helps us to better understand the differences between cells from different types of tissues that are specialized for different functions.
- What do you think is the most interesting or significant thing about the transcriptome?
Part 2: Respond to a Peer
Read a post by one of your peers and respond, making sure to extend the conversation by asking questions, offering rich ideas, or sharing personal connections.
Peer: Week 4 Discussion
“Humans and other organisms have nearly the same genes, but different cells show different patterns of gene expression. These differences are responsible for the many different properties and behaviors of cells and tissues, both healthy and diseased.
Collecting and comparing transcriptomes of different types of cells, both healthy and diseased. We can gain a deeper understanding of what constitutes a specific cell type and how that type of cell normally functions, and how changes in the average level of gene activity may reflect or contribute to disease. When there are changes in the diseased cell that is not present in the healthy cell, we can assume that that the difference in the infected cell could be a contributing factor for the disease.
I think the most interesting fact about transcriptome is, once a researcher finds an unknown gene, there is a database for researchers to use that list all the tissues of that gene, giving the researcher clues about that gene’s possible function.”
