1. Write your name on each post
2. Try to write up to three points you know about mutations  (this can include what you believe the definition of a mutation to be, the causes of a DNA mutation and the consequences of a mutation)

A mutation is a change in a DNA sequence
Mutations is important as it's the first step of evolution because it creates a new DNA sequence

# data[].attributes.body
Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses. For example sickle cell and other diseases

* A change in the DNA sequence happens
* The mutations can be that a base has been deleted, inserted or substituted
* If theres a mutation, that mutation will be replicated as DNA is replicacted.

Mutations are abnormalities in the DNA sequence , size etc.
These mutations influence protein structure  and the type of protein being made .
Can be caused by radiation
They can influence the charecterisitcs a normal gene carries thereby altering their information.

.mutation involves changes in DNA which affect the sequence of our DNA bases
.mutation can be due to mistakes during DNA replication and environmental factors

When there's less or more than the usual amount of chromosomes. Which is 23 from each parent.
When the DNA sequence has changed. Which will cause mutation in the DNA.

changes of dna
Due to mistakes of dna being copied

A change in the act of how genes behave

Types of mutation
Sickle cell anaemia
One form of beta-thalassemia
Cystic fibrosis

There are four types of mutations, one of them being deletion.

A mutation is a change that occurs in our DNA sequence, usually due to mistakes when the DNA is copied or due to other factors

Mutations can happen during cell division when a mistake occurs when the DNA is copying it self

# data[].attributes.body
can be caused by ionising radiation

Mutation can either affect you positively, negatively or none at all

mutation is a change that occurs in DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors
