Describe an evolutionary process by which a gene with new function(s) in a species (i.e. it has function(s) not found in the evolutionary ancestral species) can be generated
Homework Answers
Mutations can be a process which lead to generation of new functions from a gene in organisms. Mutations are the alteration of sequence of the DNA. Mutation can be helpful or harmful for an organism. Due to alteration of sequence, reading frame changes and during gene expression, a new protein is generated. This protein may be helpful for the organism in harsh conditions and to adapt to the environment in a better way. However, this new protein is not found in ancestral species. This type of genetic variability passed into generation after generation and also shared with existing bacteria by horizontal gene transfer. This is how mutations contribute to evolution.
Other similar processes are alternative splicing and movement of transposons etc.

You identify a gene (gene 1) in once species (species 1) that shares significant homology to a gene (gene 2) in a second species (species 2). Species 1 and species 2 share a common ancestor. Gene 1 and Gene 2 lie within in blocks of sequences that show synteny between the two species. You determine the number and identity of synonymous and non-synonymous sequence changes in the coding sequences when comparing the two genes. From these data alone (i.e., without...

Create a labeled diagram and describe the gene transfer process by which the Shiga toxin gene was picked up fromShigella dysenteriae and transferred to Escherichia coli. Be as specific as possible in your description of this process. Meaning be sure to label your donor and recipient cells as the bacterial species given depending on how the genes are being transferred.

Based on what you know about evolutionary mechanisms, which species of Emerald Finch most likely diverged from the ancestral state via genetic drift? Explain your answer. Cancer can loosely be defined as abnormal and uncontrolled growth of a tumor. Why does it make sense that Actinomycin D, which binds to transcription initiation complexes, is used as an anticancer drug?

Phylogeny is the evolutionary history of a species. a) Cytochrome C is an important mitochondrial protein found in most organisms. The table below indicates the number of similarities in the amino acids found within Cytochrome C compared across five different species. Based on the data in the table, draw a phylogenetic tree that reflects the evolutionary relationships of the organisms based on the differences in their cytochrome c amino acid sequence. Based on the data, identify which species is most...

Under the biological species concept, which of the following statements is/are true? a) Gene flow can occur between species. b) Species are independent evolutionary lineages. c) Isolating mechanisms prevent gene flow between species. d) Geographic isolation and differences in the timing of mating are two mechanisms that allow populations to genetically diverge. e) Donkeys and horses are not species.

this is an evolution question
Allopatric speciation is probably the most common way that new species form. Please describe a hypothetical scenario in which an initial ancestral population (pick whatever species you want) could split to form a new species through allopatric speciation. A fully. correct answer will at least incorporate ALL of the following terms: gene flow.divergence, natural selection (including sexual selection), genetic drift, and reproductive isolation

A new species of archaean prokaryote is found living a hot spring. When a scientist sequences its genome in an attempt to discover its evolutionary relationships she discovers something strange. Most of the genome is similar to the genomes of several well known archaean species. However one enzyme is very similar to that found in a species of bacteria that also lives in hot springs. The enzyme does not have a function related to living in hot springs. What is...
