No, because of the redundancy in the genetic code (several base triplets or codons code for the same amino acid) a point mutation, for instance, (a change in one base) may have no effect on the amino acid sequence in the protein, and so no effect on the expressed phenotype.

Mutations can cause changes in the genotype by altering the DNA sequence. These changes can then affect the phenotype by influencing the expression of certain traits or characteristics in an organism.

How can we speculate on how mutations cause changes that manifest over many generations?

Scientists can study how mutations cause changes over many generations by observing the genetic variations that accumulate in populations over time. By analyzing the frequency of mutations and their effects on traits, researchers can speculate on how these changes lead to evolutionary shifts in species.

Why aren't all mutations bad?

Mutations are unnatural changes in the body or behavior. They are not always bad. For instance, the skin of the poison tree frog is not really bad at all. It rubs itself on poison leaves and mutated itself not to be affected.

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.


Can chemicals found in cigarette smoke cause mutations to DNA?

Yes, chemicals in cigarette smoke, such as polycyclic aromatic hydrocarbons and formaldehyde, can interact with DNA and cause mutations. These mutations can lead to changes in the genetic information, which may increase the risk of cancer and other diseases.


What do mutations in genes cause?

Mutations in genes can cause changes in the structure or function of the corresponding proteins, leading to various outcomes such as genetic disorders, cancer, or altered traits. Mutations can disrupt normal cellular processes, affect gene regulation, or result in the production of abnormal proteins.
