(a) What is recombinant DNA technology (DNA cloning)? (b) Give an example of its use. When does RNA splicing take place? Why is it important? Describe the differences between genomic DNA and plasmid DNA. Plasmids are DNA vectors, which are molecular tools used by scientists in reco...
What connect genetic material, DNA and RNA in genetics? What is a transposon? a. A plasmid b. A piece of the chromosome c. A "jumping" gene d. Transferable RNA What is the human genome, and how would one explain it using haploids and chromosomes?
There have also been reports of trans-splicing in which two different primary RNA transcripts are spliced together. Combine all this with the fact that regulatory sequences (e.g., enhancers) can be found far from coding sequences, and you can see how difficult it is to define a gene.An ...
However, in certain cases, the activity of these pathways can lead to aberrant DNA repair, genomic instability and tumorigenesis. One such case is DNA repair at the natural ends of linear chromosomes, known as telomeres, which can lead to chromosome-end fusions. Here, we review data obtained ...
The genetic engineering called the gene splicing technology and the DNA reorganization technology, are take the molecular genetics as the rationales, take the molecular biology and the microbiology modern method as the method, will be different the gene which will originate according to the blueprin[...
However, in real-life genetics, this is not the case. Instead, it has been found that multiple genes often influence specific traits in the expressed phenotype of the organism. Examples of this would be pigmentation in parts of organisms or the final size of the organism. How dominant or ...
due to several limitations, microarray technology is being increasingly replaced by other high-throughput gene expression methods. This is primarily due to the limitations of microarrays in analyzing unknown genes, as well as difficulties in detecting multiple transcripts formed by alternative splicing [...
Whereas, the intron is that part of a gene in the structural region that does not take part in protein synthesis. So exon is a coding region and intron is a non-coding region. Introns lie in between exons. They are removed from the newly formed mRNA through a process called splicing. ...
Every gene is always turned on in every cell. What connect genetic material, DNA and RNA in genetics? What is the key step to sequencing a human genome, in terms of technology development (and why)? Describe how DNA sequences can reveal evolutionary relatedness. The process of f...
What are the characteristics of RNA splicing in eukaryotes? What is chromatin made of? What is the human genome, and how would one explain it using haploids and chromosomes? Which characteristic is exclusively related to the organization of DNA in eukaryotes? a. plasmids b. double-helical DNA...
