What is a cell making a copy of a gene called?
It is called gene replication or gene duplication.
What is it called when extra copies of part of a chromosome are made?
It is called gene duplication when extra copies of a gene or segment of DNA are created within a chromosome. This process can lead to genetic variation and the emergence of new gene functions.
One of the best pieces of evidence for the process of gene duplication followed by mutations is the occurrence of?
Pseudogenes, which are non-functional copies of genes that have accumulated mutations over time, are a strong indicator of gene duplication followed by mutations. Pseudogenes often have similar sequences to functional genes but lack the ability to code for proteins, supporting the theory of gene duplication and divergence through mutation.
What are the two theories of evolution in a eukaryotic cell?
The two theories of evolution in a eukaryotic cell are endosymbiotic theory and gene duplication. Endosymbiotic theory suggests that eukaryotic cells evolved from a symbiotic relationship between different prokaryotic organisms. Gene duplication theory suggests that gene duplication events have played a significant role in the evolutionary development of new functions and complexity in eukaryotic cells.
How do different organisms have the same subset of genes?
Different organisms can have the same subset of genes through processes like gene duplication, vertical gene transfer, and lateral gene transfer. Gene duplication can lead to multiple copies of the same gene in different organisms. Vertical gene transfer involves the inheritance of genes from a common ancestor. Lateral gene transfer allows organisms to acquire genes from other species, leading to the sharing of genetic material among organisms.
What is gene duplication?
Gene duplication is a key mechanism in evolution.
What is the relationship between divergence and amplification?
Gene duplication (or chromosomal duplication or gene amplification) is any duplication of a region of DNA that contains a gene; it may occur as an error in homologous recombination, a retrotransposition event, or duplication of an entire chromosome.
What is it called when a segment of a chromosome is repeated?
The mutation in which a segment of a chromosome is repeated is known as duplication.

What is it called when extra copies of part of a chromosome are made?
It is called gene duplication when extra copies of a gene or segment of DNA are created within a chromosome. This process can lead to genetic variation and the emergence of new gene functions.
Why is gene duplication seen as potentially event in evolution of species?
Yes. When a gene is duplicated you have one gene doing the job it was doing before and the possibility of the duplicated gene having a beneficial mutation and picking up a brand new job to do and making a newly beneficial protein. Of course if the mutation is deleterious that organism will not pass those genes on any further than progeny. Remember, only germline mutation are passed on to future generations.

deletion

Which types of mutation can be add genes to a chromosome?
Gene duplication is a type of mutation that can add genes to a chromosome. During gene duplication, a segment of DNA is copied and inserted into the chromosome, leading to an increase in the number of copies of a particular gene. This can result in gene families with multiple copies of a gene that may evolve new functions over time.
How can crossing over result in gene duplication?
Crossing over can result in gene duplication if unequal crossover occurs. This happens when homologous chromosomes exchange genetic material unequally during meiosis, leading to one chromosome gaining additional copies of a gene while the other loses that gene. This process can create a duplicated gene copy, which may have new functions or mutations.
