Why are introns copied and then removed from the RNA sequence?
Introns were copied and then removed from the RNA sequence because they were placeholders.
Why do the introns have to br removed?
Introns are the non-coding parts of the gene. If you didn't remove introns, the wrong protein may be produced because they allow more than one protein to be produced from a single gene.
Mutations in introns are less likely to affect phenotype then mutation in exons?
Mutations in introns are less likely to affect phenotype because introns are not translated into protein, unlike exons which contain coding regions for proteins. Introns are involved in regulation of gene expression through processes such as alternative splicing, but mutations within introns typically have a more subtle impact on gene expression compared to mutations in coding regions (exons).
Why prokaryotes do not have introns?
Prokaryotes do not have introns in their DNA because they lack a nucleus and have a simpler genetic organization compared to eukaryotes. Their genes are typically continuous sequences without interruptions, unlike eukaryotic genes which can have introns that need to be spliced out during gene expression.
CDNA is significant when?
cDNA is significant because it is a synthesized DNA copy of mRNA that lacks introns and contains only exons. This allows for the study of gene expression and regulation, as well as the production of recombinant proteins or gene therapy vectors. cDNA is particularly useful in understanding genetic diseases and developing new therapeutics.
Why are introns copied and then removed from the RNA sequence?
Introns were copied and then removed from the RNA sequence because they were placeholders.
Can the cultural evolution occur faster than biological evolution?
Yes, cultural evolution can occur much faster than biological evolution because cultural traits can be rapidly spread and adopted among populations through communication, imitation, and technology, whereas biological evolution relies on genetic changes that accumulate over generations through the process of natural selection. This allows cultural adaptations to occur more rapidly in response to changing environments or social needs.

How are fossils evidence of biological evolution?
Fossils are evidence of biological evolution because they provide a record of past life forms, showing the progression of species over time. By studying fossils, scientists can trace the development and diversity of organisms, providing insight into how species have evolved and adapted to changing environments.
How is co-evolution significant in community ecology?
because it determines whether a species will evolve to keep up with its predator or prey
Why do eukaryotes have introns in their genetic material?
Eukaryotes have introns in their genetic material because they allow for alternative splicing, which enables a single gene to code for multiple proteins, increasing genetic diversity and complexity.
Why is Leonardo Da Vinci considered to have made a 'significant contribution' to society?
Leonardo Da Vinci considered to have made a 'significant contribution' to society because of the significant contribution that he made to evolution.
Did the environments Darwin studied exhibit little biological diversity?
Darwin study the Islands of the Galapagos off the coast of Ecuador. These Islands had a large amount of biodiversity which was very astonishing because of there size and remoteness. Each island had its own species of the same animal which is why it was a great place to study the effects of evolution.
Why introns are removed before cloning a gene?
Introns are removed before cloning a gene because they do not code for proteins and their presence would result in inconsistencies in the protein sequence. Removing introns ensures that the cloned gene only contains the coding regions (exons) necessary for protein production. This process is known as splicing.
Why is the Galapagos Islands significant to the theory of evolution?
The Galapagos Islands are significant to the theory of evolution because they inspired Charles Darwin's ideas on natural selection. Darwin's observations of unique species on the islands led to his theory that species can adapt and evolve over time to better survive in their environment.
