Explain, in general terms, the role of RNA in gene expression. Why is RNA useful to a cell? What is the benefit of using RNA instead of just directly producing protein from the instructions in DNA? How does the transcription of DNA to RNA work?
What are the steps in DNA replication? Explain how DNA encodes a cell's information. How does the transcription of DNA to RNA work? How does RNA decompose in the cell? How is information stored in the DNA molecule? Describe the structure of DNA and the steps of protein synthesis. ...
Supercoiling is a term used to describe what happens when the two strands of a double-stranded, double helical DNA molecule are separated from each other, which occurs during DNA replication and transcription. One way to visualize supercoiling is to think about what happens when you twist a ...
Systemic lupus erythematosus (SLE or Lupus; OMIM 152700) is an immune-mediated disease associated with a lower life expectancy due to an increased risk of major infections and renal and cardiovascular complications [1,2] Like other rheumatic diseases, such as Sjögren’s syndrome, systemic scleros...
Incidents of viral outbreaks have increased at an alarming rate over the past decades. The most recent human coronavirus known as COVID-19 (SARS-CoV-2) has already spread around the world and shown R0 values from 2.2 to 2.68. However, the ratio between m
(PDB ID: 6FM1). However, it remained still largely unknown how the phage S-2L incorporates the base Z in its genome, especially as no gene corresponding to a DNA polymerase could be detected. This is in contrast with the situation in the phage φVC8, where a DNA polymerase of the ...
IPTG functions as an inducer of the lac operon, and x‑gal helps researchers determine whether the cells contain recombinant DNA. Bacterial colonies with an empty plasmid (i.e., plasmids without a DNA insert) turn blue. This occurs because of a process called alpha-complementation in which...
Proteins interact with each other, as well as with other components of the cell, which is done in an incredibly active manner. Virtually all cellular processes involve the formation of protein complexes, frequently involving RNA, DNA, and/or other biological molecules, too. Location, ...
Why is the mitochondrial DNA linked to errors and what happens to your cells when this DNA mutates? Explain the importance and process of DNA proofreading and repair. What are at least two steps in DNA and RNA transcription where an error could be made? Since proteins are what we are mad...
A sequence in the DNA called the promoter determines which strand of DNA will be the used as the template for transcription of a particular gene. The... Learn more about this topic: mRNA Transcription Process & Phases from Chapter 9/ Lesson 2 ...
