What if the cellular process that carries out hereditary instructions would be affected by a mutation?

Depending on the type of mutation, this could be harmless, or it could be harmful and even lethal.
For example, a point mutation changes one base in a codon. Since most amino acids have more than one codon, this mutation may still code for the same amino acid. For example, both TTT and TTC codons code for the amino acid phenylalanine, so if TTT was mutated to TTC, the mutation would have no effect.
However, in sickle cell anemia, a life-threatening genetic disorder, is also caused by a point mutation, in which the codon CTC is mutated to CAC. The codon CTC codes for the amino acid glutamine, and CAC codes for the amino acid valine. This change in just one codon causes the hemoglobin molecule to have an altered structure, which causes the red blood cells carrying the mutated hemoglobin molecule to be stiff and have a concave (sickle) shape. The sickle-shaped cells clog blood vessels and do not transport oxygen effectively, which causes pain and damage to the organs, shortening the lifespan by about 30 years. A person must inherit the mutated gene from both parents in order to be affected.

There are other types of mutations, such as frameshift mutations, and chromosomal mutations that can negatively impact the affected organism.

What is a permanent heritable change in an allele that produces a different variant of the same trait?
heritable change occurs in a line of descent
What is a cellular disease?
A cellular disease is either a mutation of the DNA cells or a overload of cells in one particular disease
What is a gene mutation?
Gene mutation is the change in the DNA sequence that is permanent and leads to new genetic traits and even diseases. This type of mutation is triggered through hereditary process or through several factors in the environment.
If a nucleotide pair were removed from a gene what would be affected?
Every pair in the sequence after that pair would be affected. Probably resulting in a mutation.
Mutations in mitochondrial genes often cause disorders that affect cells?
the mitochondrial mutations effect to those cells which have maternal inherritance character and the mutation is called poky mutation
What changes in a mutation?
hereditary instructions
What do you call a change in the hereditary instructions of an organism?
which is a change in an organism's genes that can be passed from parent to offspring
A mutation is a change in a?
gene sequence
What are the forms of mutation?
== ==mutation means:change in a hereditary character
What does mutation?
mutation means: change in a hereditary character
Mutations in body cells can be passed on to offspring of the affected individual?
No. As long as the mutation does not occur in the reproductive cells (sperms or ovum), it will not be pass on to the offspring.
What is changes in hereditary material called?
It is called a mutation.
What is a permanent heritable change in an allele that produces a different variant of the same trait?
heritable change occurs in a line of descent
Is sickle cell anemia a point mutation?
An example of point-mutation is sickle-cell anemia. Sickle-cell disease is hereditary.
What is the type of mutation that causes deafness?
that would be a hereditary thing not a gene mutaion
What is the alteration of genetic material at the cellular level is?
mutation
Sickle-cell anemia is an example of a point-mutation?
An example of point-mutation is sickle-cell anemia. Sickle-cell disease is hereditary.
