I post this question twice, please don't answer this post if you already answer the other one, if you can answer different answer that's fine. REASON WHY I POST IT TWICE, I NEED TWO DIFFERENT VIEW.
Discussion
Hi All - this week you will learn about DNA - the molecule of life! You may think that protein-coding genes are the most important, but results from the Human Genome Project revealed that only about 2% of our DNA codes for protein - so what about the rest of the "junk DNA" (or non-protein coding portion of the genome) - is it functionally important? Yes! Scientists are learning how "the non-protein-coding portion of the genome is of crucial functional importance: for normal development and physiology and for disease". I would like you to please choose a topic with regards to the non-protein coding portion of the genome (this will introduce you to gene regulation which we will cover in chapter 11) or you may also choose to write about a topic that describes a mutation in any protein that is involved in DNA replication, transcription, or translation (we did not talk about all of the enzymes involved in those processes). Please list your reputable source - this is worth 0.5 pt (even if you use one of my sources below) and tell me WHY you chose your topic (this is worth 1 pt.) please try to briefly explain your topic to the best of your knowledge - I don't expect you to write a lot of detail about your topic - it might be hard to understand (which you are welcome to comment on in your paragraph)!
Examples to choose from (but not limited to) include: noncoding RNAs (snRNAs, miRNAs, siRNAs, snoRNAs, piRNAs, lincRNAs) and RNA therapeutics:
