What is the effector mediating the response? What are the steps of the scientific method? Explain each step. Describe the difference between an acid solution and a basic solution at the molecular level. Why do we need to know biology?
not tissue- or cell-specific, this approach may not be sufficient to determine the specific tissue in which the expression is detected [7]. To overcome these challenges, the ideal solution is the isolation of specific tissues. In the case of secondary growth, it is possible to manually separa...
What Is Genetic Engineering? Technology What Is Solar Power? Biology What Is the Largest Predator That Ever Lived? Related Articles Discussion Comments ByCharred— On Feb 03, 2012 @Mammmood - I can’t answer your second question, but as to the first question, don’t put hair gel on your...
This arises due to the utilization of alternative promoters, and is further compounded by significant variability with regards to the precise transcriptional start sites of each (not to mention alternative splicing). Consequently, the transcript for a protein coding gene is not a unique mRNA, but ...
Splicing of pre-mRNAs by the spliceosome plays a key role in tissue development [73, 74]. Genome wide splicing analysis revealed an increased number of spliced genes during aging [75, 76]. Changes in spliceosome gene expression and alterations in pre-mRNA splicing are associated with lifespan ...
Which of these is a level or type of genetic regulation in eukaryotes? Select all that apply: A) Post-translational B) Transcriptional C) DNA methylation D) RNA splicing E) Co-transcriptional Why are most genes controlled at the level of transcription?
Explain or define the following term: Gene splicing. How can antisense RNA be used to increase the translational efficiency of gene expression? How does mutation in telomerase impact DNA replication in dyskeratosis congenita? Describe genetic code. In an operon that is under negative inducible control...
Why is transcription needed? What is the difference between the process of translation and transcription? What is the region of DNA where sigma factors bind to start transcription called? How are enzymes involved in the process of genetic transcription? Explain the processes of splicing, capping, ...
Chromatin in eukaryotic cells is a negatively charged long polymer consisting of DNA, histones, and various associated proteins. With its highly charged and heterogeneous nature, chromatin structure varies greatly depending on various factors (e.g. chemical modifications and protein enrichment) and the ...
The POSTN molecule comprises four fascia I domains, a cysteine-rich domain in the N-ter- minal region, and an alternative splicing domain in the C-terminal region [51–56]. POSTN binds to both type I collagen and fibronectin [56, 57], is involved in collagen fibrosis, and is also ...
