What is the role of an antibiotic resistance gene in the plasmid DNA? Explain how plasmids are used in gene cloning. How can a diagram explain plasmid with the necessary enzymes? What are plasmids? Why are they important for genetic engineering?
In biological terminology, the operon generally represents a group of genetic makeup which works collectively to produce an mRNA (messenger RNA) unit. Such nucleotide sequence is widespread in microorganisms. Its characteristic enables polypeptide production to be coordinated in reaction to the cell's ...
In tryptophan synthesis pathway, tryptophan acts as a corepressor. What is its role as a corepressor?Solution in Telugu A It prevents transcription of the genes of the operon B It binds to the promoter that blocks the attachment of RNA polymerase C It binds to the tryptophan repressor to ...
L-Arabinose is a plant-specific sugar that plays a role in cell wall synthesis and the metabolism of L-Ara-containing molecules in plants. It has potential applications in natural medicine synthesis. L-Arabinose is an important component of the mycobacterial cell wall and is involved in modulatin...
the “spike” at the end of the tube, which serves to puncture the membrane of the target cell, so that the effector proteins can be delivered. PAAR repeat containing proteins have been found to play an important role in the formation of the puncturing structure at the top of the tube, ...
Operon: Operon is a structure in DNA and contains multiple functional genes. Prokaryotes like bacteria and archaea contain an operon structure, but eukaryotes lack it. Operon is a method of gene expression and is responsible for polypeptide synthesis. Answ...
What is imprinting and what is the role of DNA methylation in it? What are the proteins involved in homologous recombination? What is the relationship between genes and genome? What is DNA sequencing? What is frameshift mutation? What is methylation and where does it usually occur?
Nutrient starvation, antibiotic stress, heat shock, DNA damage and other kinds of stresses are shown to elicit mazEF-mediated-PCD. ppGpp and extracellular death factor play a central role in regulating mazEF-mediated PCD. The activation of mazEF system is achieved through inhibition of transcription...
The activity of enhancers can be highly tissue-specific or developmental stage-specific, enhancing gene expression in particular cells or at certain times. Promoters, while also capable of being tissue-specific, generally have a more consistent role across different cell types. 6 ADVERTISEMENTComparison...
A gene is a segment of DNA encoding a functional product; a cistron is a gene unit for function, reflecting its ability to be expressed as a phenotype.
