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 all...
If an mRNA nucleotide is synthesized from DNA, how do you identify the: a) 5' end, b) 3' UTR, c) Polyadenylation signal, d) 3' end, e) Exon, f) Translation start codon, g) Promoter region, h) 5' cap, i) Translation stop codon and j) Intron. ...
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 si...
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 was dystrophin synthesized from out-of-frame mRNA in his muscle? We hypothesized that the splicing of DMD pre-mRNA was modified to produce in-frame mRNA. To test this, we amplified DMD mRNA from exons 42 to 47 from muscle RNA by RT-PCR. Remarkably, we obtained two amplified products...
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 ...
Endorphins get all the attention, but your body also pumps out endocannabinoids, which are a naturally synthesized version ofTHC, the chemical responsible for the buzz thatmarijuanaproduces. The most examined endocannabinoid produced in the body, anandamide, is believed to create a feeling ofcalmness...
How does DNA replication work? Why is adenine used for energy more than the other nucleotides? Why does DNA methylation occur? Why is ribosomal DNA used for sequencing? What is leading strand in DNA replication? Why is there no thymine in RNA? What s...
During DNA replication, which strand is the lagging strand? Why can't both strands be synthesized in the same manner? What is an antisense strand in DNA replication? How does DNA replicate itself? What happens in a cell if all the chromatin is in condensed form? a. There will be DNA re...
