Reflection Questions
- What is the biggest discovery that I made from these readings?
The major discovery from these readings is the author's confirmation that messenger RNA is essential for protein synthesis within cells. Through experiments utilizing bacterial extracts and ribosomes, the author investigated the role of RNA and DNA in protein production. Using a more sensitive test, they determined that only RNA from ribosomes, not DNA, played a key role in facilitating protein synthesis. This finding significantly advanced our understanding of cellular processes. The author also highlighted methodological enhancements, including the freezing of extracts and process optimization, which contributed to the overall effectiveness of their research (https://www.sciencedirect.com/science/article/pii/S0968000403003025)
- What part of the readings did I understand the least?
The confusing aspects to me in the reading came from the details surrounding the chemical diversity of proteins. The focus on amino acids, with their varied structures and unique side chains R groups is challenging to grasp, especially considering the many sizes and complexities involved. The introduction of the additional amino acid selenocysteine and its role during protein synthesis guided by a modified genetic code interpretation adds a layer of complexity. The discussion of modifications during protein processing, including acetylation, phosphorylation, and the attachment of large side chains with sugar units, was confusing to me. https://www.ncbi.nlm.nih.gov/books/NBK21121/#A5818
