One thing to notice in Deppe's quote is that a mutation in a single gene may have no effect on an organism, or its offspring, or its offspring's offspring. For example, imagine an animal that has two identical copies of a gene in one allele. A mutation changes one of the two genes...
How does epigenetics alter our basic understanding of inheritance? How could understanding epigenetics help us in research? How is an epigenetic change different from a mutation? Explain how heritability affects the speed of evolution. In real life, how much do genetics affect personality traits as ...
A mutation changes the DNA of an organism in a way that affects its offspring, either immediately or several generations down the line. The change brought about by a mutation is either beneficial, harmful or neutral. If the change is harmful, then it is unlikely that the offspring will ...
How does genetic drift affect mutation?Genetic Drift:Genetic drift is the change in the available alleles and their prevalence in a breeding population. Usually, this occurs over an long period as some genes become more common and others becomes less common. Catastrophic population loses, however,...
What Is a Genome? Genomes are sequences of DNA that contain all the genetic instructions needed to build and maintain living things, including humans. The genome is the complete set of genes present in an organism. It contains all hereditary traits and determines what physical and behavioral fea...
Our non-coding DNA could dictate an organism's ability to speciate. Speciation is the term that described the ability to evolve into a new species, and it could be heavily influenced by so-called ‘satellite dna’. This is DNA that encompasses our coding DNA, and gives it structure. The ...
DNA polymerases were named for their function of catalysing DNA replication, a process that is necessary for growth and propagation of life. DNA involving Watson–Crick base-pairing can be synthesized with high fidelity, the structural and mechanistic or
Protein coding features can emerge de novo in non coding transcripts, resulting in emergence of new protein coding genes. Studies across many species show that a large fraction of evolutionarily novel non-coding RNAs have an antisense overlap with protei
Explain what a mutation is and the affects they might have on an organism's phenotype. Can someone explain how bacteria evolve resistance to antibiotics using the process of Natural Selection terms: Mutation, Variation, Survival with Produce, and Selective Pressure?
How would a genetic mutation affect our evolution? How evolution happens? What is natural selection and how does it work? Explain using examples. Explain whether a mutation affects the organism itself or the organism's offspring. How does spont...
