Which one of an intron and exon is the reminiscent of antiquity?
The introns are removed during processing by splicing & the exons are joined. The presence of introns in primary transcript is the reminiscent of antiquity.
What is the evolutionary significance of introns?
Evolutionary advantages of introns include the possibility to create new genes by cutting and pasting exons from existing genes or to diversify the protein output of a single gene by splicing the exons together in different ways.
What is reminiscent in biology?
noun In biology, the retention by a modern organism, during its development, of traces of the effect of past ancestral history. noun The act or power of recollecting; recollection; the voluntary exertion of the reproductive faculty of the understanding; the recalling of the past to mind.
How does split gene represent an ancient feature of genome?
The split- gene arrangement represent probably an ancient feature of genome. A split gene or interrupted gene contains both exons and introns. Exons are the sections of the gene which can be expressed into RNA and proteins.
Why is hnRNA needed under splicing?
hnRNA is required to undergo splicing because of the presence of introns (the non-coding sequences) in it. These need to be removed and the exons (the coding sequences) have to be joined in a specific sequence for translation to take place.
Which structure is considered as reminiscent of antiquity?
Reminiscent of antiquity refers to the Introns which have no role in protein synthesis. Explanation: the dna sequence consists of Introns and exons.
Is reminiscent a feeling?
adjective. Tending to bring a memory, mood, or image, for example, subtly or indirectly to mind: allusive, connotative, evocative, impressionistic, suggestive.
What do exons and introns do?
Introns are noncoding sections of an RNA transcript, or the DNA encoding it, that are spliced out before the RNA molecule is translated into a protein. The sections of DNA (or RNA) that code for proteins are called exons. Splicing produces a mature messenger RNA molecule that is then translated into a protein.
Why is under splicing necessary?
During splicing, introns are removed and exons are joined together. For the eukaryotic genes that contain introns, splicing is required in order to create an mRNA molecule that is capable of being translated into a protein.
What does “presence of introns is reminiscent of antiquity” mean?
“Presence of introns is reminiscent of antiquity” implies that introns were previously in past an important pieces of information used to form mRNA but now are of no importance. Rate! Rate! Reminiscent of antiquity refers to the Introns which have no role in protein synthesis.
What does the presence of introns in RNA represent?
This discussion on EXPLAIN THE STATEMENT :: The presence of introns is reminiscent of antiquity, and the process of splicing represents the dominance of RNA world. is done on EduRev Study Group by NEET Students.
Why do introns only cause variations in individuals?
EXPLAIN THE STATEMENT :: The presence of introns is reminiscent of antiquity, and the process of splicing represents the dominance of RNA world. introns only cause variations in individuals .So they are necessary for variations
What do you mean by reminiscent of antiquity?
Reminiscent of antiquity refers to the Introns which have no role in protein synthesis. the dna sequence consists of Introns and exons. the entire segment of the dna is not responsible for the production of protein by the process of translation
