How is the structure of DNA different from the structure of RNA? Draw the specific structure of each nucleotide and the proteins each uses. Describe the basic structure of DNA. Discuss why DNA is often called a "protein recipe". Describe how the structure of DNA allo...
Why is tRNA called soluble RNA? Compare the tRNA and mRNA in terms of their functions and how they are synthesized within the cell. Describe mRNA splicing. Explain the second genetic code, with respect to tRNA specificity. A) How does a tRNA get connected to an amino acid? B) What are...
Explain how the lagging strand is synthesized even though DNA polymerase can add nucleotides only to the 3' end. Describe the significance of Okazaki fragments Explain the role of RNA polymerase in transcription. Explain how you could use the nucleic acid sequence of RNA f...
At the individual level, the reproductive investment of females, which is responsible for seed production, is usually greater than that of males, which is responsible for pollen generation7. However, determining the reproductive allocation within a population is complicated because (1) in some wind-...
How would you define a prokaryotic cell? 1. What is the cell membrane? 2. What does it contain? How does it function? 3. Is it prokaryotes or eukaryotes? Describe how a newly synthesized integral protein (other than those of mitochondria and chloroplast) with a sin...
Small homeostasis defects were found in rai1, dcs1, and xrn1, which are involved in RNA processing. We cannot exclude the possibility that size homeostasis is generated by some unknown essential gene. Global Scaling of mRNA Abundance with Cell Size It is unclear how gene expression changes as...
For the latter, how does the cell know which switches are to be activated or deactivated; will the cell divide, differentiate, transform or undergo apoptosis or otherwise change its status? What intelligence is required to make these decisions; what is the messenger molecule and how does the ...
1. Introduction Cancer is a systemic disease involving multiple time- and space-dependent changes in the health status of cells and tissues that ultimately lead to malignant tumors [1,2]. Dysregulated cell growth, i.e., neoplasia, is the biological endpoint of the disease [3]. Tumor cell ...
(They focused on saliva because it contained information on RNA, which is what your DNA uses to make feel-good proteins like natural opioids and cannabinoids.) But not everyone’s processes it at the same degree, meaning you might have a runner’s high, while your running partners are ...
Protein synthesis is accomplished through two processes: transcription and translation. With the help of RNA polymerase, RNA is synthesized from DNA...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question...
