Mutations

What can cause the mutations in a DNA sequence?

Mutations can be caused by errors in replication, transcription, cell division, or by external agents. This can change the sequence of nucleotides within a gene. If a mutation occurs the offspring can be changed dramatically.

There are many things that bring about mutation. Some are errors in replication and transcription, cell division. IT changes the sequence of nucleotides within a genes.

DNA Mutations can be caused by many things. One thing that can cause mutation are errors in replication, transcription, and cell division. This changes the sequence of nucleotides within the gene.

Mutations can be caused by errors in replication, transcrption, cell division, or by external agents. This chenges the sequence of nucleotides within a gene. If mutation occurs the babies can be changed.

mutations can happen because of a lot of things there is sometimes an error in replication but there are other things that cause them too. if there is a mutation the next generation will have the same mutation

it is a error in the replication of a cell. it could also be from external agents. a mutation can me small to a large change.

Mutaions can be caused by errors in replication. This can change the sequence of nucleotides within a gene. If this occurs the offspring can change dramatically.

A mutation can be caused by many things. It can be caused by errors in transcription and cell division. This can chnge the sequence of nucleotides within a gene. This can result in a new trait in an offspring

Mutations can be caused by mistakes in the DNA repairing and copying process. They can also be caused by exposure to radiation of varoiuos other harmful substances.

Mutations can cause an error in replication, transcription, or cell division. It changes the sequence of nucleotides within a gene. Mutations also cause change in an offspring.

Mutation can be caused by many things. It could be caused by errors in replication, transcription, and cell division. This can cause offspring to have many disorders or syndroms.

Mutations can be caused by cell division, replication, and transcription. If mutation happens the order of nucleotides changes within the gene. If a mutation happens, the offspring will be affected by the change.

Mutations can be caused be errors in replication, transcription, cell division, or be external agents. Any of these can change the sequence of nucleotieds within genes. Like one mutation can cause cancer or other mutations but our body is able to catch these mutations.

Mutations is a change in DNA. It can happin cell divishon or DNA replicatshoin. If it happins it can cause cansr.

A mutations are what happens when the body misreads a squence or stran. Mutation is how animals and people evelove there the time. Mutations happen more when you are older because your body is can't reconize things fast enough.
