Imagine copying a transcript by hand in a driving car. Every letter, every sequence of letters, must be correct, but because of the disruption in a moving car causes your hand to move, you might make a mistake. This is what happens to our DNA when it eventually replicates, required for cell replacement/division. What causes this mistake; mutagens like radiation (UV, gamma), viruses, chemicals (tobacco), etc. Some people are genetically more at risk than others.

What are known as gene mutations and occur at a single point in the DNA sequence?
Mutations that occur at a single point in the DNA sequence are Point Mutations.
Changes in DNA are called mutations?
the answer is mutations.......................
Mutations are changes in?
changes in DNA
Genetic information is alterd when changes in the DNA sequence is called?
It is called mutations. I'm 100% sure.
What cell cause mutations?
DNA polymerase
What can cause changes in DNA sequences?
mutations
What are known as gene mutations and occur at a single point in the DNA sequence?
Mutations that occur at a single point in the DNA sequence are Point Mutations.
Changes in DNA are called mutations?
the answer is mutations.......................
How does polymerase prevent mutations?
It checks DNA for errors during replication.
Sometimes mutations in DNA can cause control of the cell cycle to fail. What might happen if such a mutation occurred in a person's DNA?
The failure of DNA replication during the cell cycle can cause mutations. If such mutations occurred in a person's DNA, the person can end up getting cancer.
What is a source of genetic variation that refers to a random error in the genetic code?
Mutations involve changes in the DNA code.
Changes in DNA is called?
mutations
Mutations are changes in?
changes in DNA
What do changes in the DNA sequence or mutations help drive?
Evolutionary Change refers to the changes in the DNA sequence or mutations to help drive.
Genetic information is alterd when changes in the DNA sequence is called?
It is called mutations. I'm 100% sure.
How can mutations cause genetic mutations in spite of your body's DNA repair enzymes?
Mutagens cause a change in DNA and by this way they can produce mutant DNA repair enzymes.
What is one way that can occur in a DNA sequence?
Mutations (point mutations, inversions, translocations...) cause changes in DNA Simply stated, a mistake made while DNA copies causes changes in DNA.
