It will affect protein synthesis. mRNA uses DNA (a gene) as a template and mRNA is a template to join amino acids together. If the DNA sequence (gene) is changed, the mRNA will be changed, and the polypeptides will be changed - usually with harmful consequences. Proteins produce phenotypes in organisms, so a mutation in DNA causes abnormalities.

What are the changes in DNA sequences that affect genetic information known as?
Mutation
What can cause changes in DNA sequences?
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 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.
What are the changes in DNA sequences that affect genetic information known as?
Mutation
What DNA mutations are directly linked to inherited diseases?
the ones that have to do with the stuff that is involved such as sexual defencicies
How do DNA mutations affect cells?
Cells are dividing through the processes of Mitosis and Meiosis. DNA mutations directly affect cells by making them divide non-stop. This is known as Cancer. Proto-oncogenes, a gene involved in cell division mutates and becomes oncogenes that orders cell mechanism of division to go on continously even though the DNA found in a cell's nucleus is already damaged. this causes abnormal cell division.
What does DNA replication directly affcet or make possible?
What does DNA replication not directly affect or make possible
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 are substitution mutations caused?
A substitution mutation in genetics is where one of the nucleotide bases of DNA is swapped for another. These mutations may or may not affect the protein that is being coded.
Can you tamper with DNA?
Not directly. Radiation can cause mutations in DNA. Excess heat (as in the case of a fever) can denature (destroy) the DNA sequence as well as other proteins which will usually result in cell death.
How does chemestry affect cancer?
Chemicals that do not cause cancer by themselves but can act with another chemical to cause cancer (cocarcinogens). Damage to DNA in cells can lead to cancer. ... Unrepaired DNA damage can lead to mutations, or changes, in genes, and mutations in certain genes can cause cancer. You can also inherit mutations.
How can mutation affect the mRNA?
Mutations not only change the DNA, but a change to the DNA will change the mRNA. This explains why a mutation in one generation can be passed on to the next generation.
How does polymerase prevent mutations?
It checks DNA for errors during replication.
