selfish dna การใช้

• While some TEs confer benefits on their hosts, most are regarded as selfish DNA parasites.
• Since retrons are not mobile, their appearance in diverse bacterial species is not a " selfish DNA " phenomenon.
• What is more, it is not always easy to distinguish between some instances of selfish DNA and some types of viruses.
• Sometimes known as " selfish DNA, " they usually carry little information beyond what they need to cruise around the genome.
• Richard Dawkins suggested the idea of selfish DNA in reaction to the then fairly new revelation of the large proportion of noncoding DNA in eukaryotic genomes.
• Irrespective of the strict definition of selfish DNA, there is no sharp, definitive boundary between the concepts of selfish DNA and genetically functional DNA . Often it also is difficult to establish whether a unit of noncoding DNA is functionally important or not, and if important, in what way.

• After a conversation one night with his friend Mr . Ooze in the Gripe Pit selfish DNA, no higher aspiration ( besides an elevator between Nil and Hell, Nil sports individuals whose workaholic existence leaves them no time to think about alternatives ) in life, and no pleasure beyond the cynical moment.
• Typically, the DNA transferred consists of the genes required to make and transfer pili ( often encoded on a plasmid ), and so is a kind of selfish DNA; however, other pieces of DNA are often co-transferred and this can result in dissemination of genetic traits throughout a bacterial population, such as antibiotic resistance.
• In the purest forms of the concepts, units of genetically functional DNA might be viewed as " replicating entities " that affect their replication by manipulating the physiological activities of the cell that they control; in contrast, units of selfish DNA affect their replication by exploiting existing DNA and DNA-manipulating mechanisms in the cell, notionally without significantly affecting the fitness of the organism in other respects.
