Result in early embryonic death, disease, deformity, have no obvious effect, have a long term positive effect if the mutation is beneficial to the subject organism's species as a whole and if environmental pressure increases the survival rate of individuals with the trait. Frequency of occurrence can decrease or increase based on genetic drift in smaller isolated populations.

Changes in DNA sequence of a single gene are called?
Changes in a DNA sequence of a single gene is called a point mutation. These mutations can be harmful or not to the organism.
Why would a change in DNA sequence change that organism?
In an organism, a genetic code is made by the cells, but in that genetic sequence, if one or more letters are change, replaced, or deleted, then those cause mutations in the organism In an organism, a genetic code is made by the cells, but in that genetic sequence, if one or more letters are change, replaced, or deleted, then those cause mutations in the organism
What is the difference between an old and a new strain of DNA?
An old strain of DNA refers to the original sequence of genetic code, while a new strain refers to a mutated or altered version of the DNA. Mutations in the DNA sequence can lead to differences in characteristics or functions of an organism.
What is the best definition of mutation?
A mutation is a change in the DNA sequence of an organism, which can result in alterations to the characteristics or traits of the organism. Mutations can occur spontaneously or be induced by various factors such as chemicals or radiation.
What do changes in the DNA sequence or mutations help drive?
Changes in the DNA sequence or mutations can drive evolution by introducing variation within a population. This variation can provide individuals with different traits that may be beneficial for survival and reproduction in a changing environment. Over time, natural selection acts on this variation, leading to the gradual accumulation of advantageous traits in a population.
Changes in DNA sequence of a single gene are called?
Changes in a DNA sequence of a single gene is called a point mutation. These mutations can be harmful or not to the organism.
How do mutations occur in an organism?
In the base sequence of the DNA part of the DNA changes which causes a change in the whole DNA which is called a mutation.
How does DNA affect an orginsims traits?
DNA carries the genetic information that determines an organism's traits. The sequence of nucleotides in DNA determines the sequence of amino acids in proteins, which are essential for an organism's structure and function. Mutations in DNA can result in changes to an organism's traits.
Changes in DNA are called mutations?
That's correct. Mutations are changes in the DNA sequence that can result from errors during DNA replication, exposure to mutagens, or other environmental factors. Mutations can have various effects, ranging from no impact to influencing an organism's traits or health.
What is a cell mutation event within a DNA sequence?
It is permanent change of the nucleotide sequence of the genome of an organism.
A mutation is a change in DNA sequence and what?
A mutation is a change in the DNA sequence that can lead to alterations in the protein produced or affect the functioning of the gene. Mutations can arise spontaneously or be induced by external factors like radiation or chemicals. Some mutations can be harmful, while others may have no effect or even be beneficial.
A change in the sequence of bases in a strand of DNA that occurs as a result of exposure to x-rays is an example of?
A change in the sequence of bases in DNA caused by exposure to x-rays is an example of a mutation. Mutations are alterations in the DNA sequence that can have various effects on an organism's traits or phenotype. In this specific case, x-rays can cause genetic mutations by damaging the DNA structure.
Why would a change in DNA sequence change that organism?
In an organism, a genetic code is made by the cells, but in that genetic sequence, if one or more letters are change, replaced, or deleted, then those cause mutations in the organism In an organism, a genetic code is made by the cells, but in that genetic sequence, if one or more letters are change, replaced, or deleted, then those cause mutations in the organism
What are the raw material of evolutionary change?
Mutations are considered as the raw materials of evolutionary change. They are structural changes in the DNA sequence of an organism.
How can a mutation in DNA base sequence causes a change in trait?
Some mutations produce new traits that can help an organism survive.
How can a mutation a DNA base sequence cause a change in a trait?
Some mutations produce new traits that can help an organism survive.
How can a mutation in DNA base sequence cause a change in a trait?
Some mutations produce new traits that can help an organism survive.
