The molecular clock is used to estimate the time of occurrence of events called speciation and radiation. The molecular data used for such calculations is usually nucleotide sequence for DNA or amino acid sequences for proteins. In other words, a protein is known as a molecular clock because it changes over time.

Why was Robert hooke discovery an important foundation for the work of Watson and crick?
Robert Hooke's discovery of cells and his work on microscopy laid the foundation for understanding the structure of biological organisms. This knowledge was crucial for Watson and Crick to later propose the double helix structure of DNA, as it provided a basis for their molecular model. Hooke's observations helped establish the idea that living organisms are composed of cells, which informed further research in genetics and molecular biology.
What is molecular evidence for evolution?
Molecular evidence for evolution includes DNA sequencing, which reveals similarities in the genetic code across species. By comparing the DNA sequences of different organisms, scientists can infer evolutionary relationships and common ancestry. Additionally, the presence of pseudogenes and shared genetic markers further supports the idea of evolution through common descent.
Which model of evolution shows change over a relatively short period of time?
The punctuated equilibrium model of evolution suggests that evolution occurs in rapid bursts of change separated by long periods of stability. This model emphasizes the idea that species evolve quickly in response to environmental changes, leading to abrupt shifts in their characteristics over relatively short periods of time.
What is the scientific basis behind the idea that humans are made out of stars?
The scientific basis behind the idea that humans are made out of stars is that the elements that make up our bodies, such as carbon, oxygen, and nitrogen, were created in the cores of stars through nuclear fusion. When these stars exploded in supernova events, these elements were scattered into space and eventually formed new stars, planets, and life forms, including humans. This connection between the elements in our bodies and the processes that occur in stars is what leads to the poetic notion that we are made of stardust.
What is the dull pain behind my right rib cage?
A dull pain behind your right rib cage could be caused by various conditions such as gallbladder issues, liver problems, muscle strain, or even gas. It is important to consult with a healthcare provider for proper diagnosis and treatment.
What is the main idea behind the model of of a molecular clock?
The main idea behind the model of a molecular clock is that neutral mutations accumulate at a steady rate.
Any idea what a Herschede grandfather clock antiqua model 525 might be worth?
It is a rare model and worth about $25K!
On what concept does the molecular clock rely?
The molecular clock relies on the idea that mutations in DNA accumulate at a relatively constant rate over time. By analyzing these mutations, scientists can estimate the time at which different species diverged from a common ancestor.
How do you sell a game idea to a company?
first of all the plans have to be drawn up and all the ideas put on paper. you then have to patent your idea as so as you own the copyrights. the then build a prototype model and use that as the sales model to try and seel the idea behind the model to a corporation
What model is used to determine molecular shape?
The VSEPR (Valence Shell Electron Pair Repulsion) model is commonly used to determine molecular shape. This model is based on the idea that electron pairs in the valence shell of an atom repel each other and thus orient themselves in a way that minimizes repulsion to give the molecule its shape.
Who used a question and answer method of arriving at important truths?
Socrates. This is the idea behind Socratic method.
What does the US debt clock actually mean?
The US debt clock idea is a graphic way of describing the national debt as part of a clock. As the debt gets larger then the hands on the clock move. The same sort of idea is used for the world risk from nuclear destruction.
Can you give the idea for preparing a model on hazards?
can you give idea for a model on hazards
What does the idiom to get behind an idea mean?
To get behind something means to support it.
The general idea behind the electron transport chain is?
That ADP is converted to ATP and also that electrons are shuttled down the chin of electron acceptors, until molecular oxygen acts as the final electon acceptor.
What is the idea behind the age limits?
The idea behind the age limits is to give everyone an equal chance and ensure productivity.
What are the scientific models?
computer model, idea model, and physical model
