False. A mutation refers to a change in the DNA sequence of a gene or chromosome, not the specific part of a chromosome that carries information about a trait.
A mutation is a change in genes or chromosomes that causes a new trait to be inherited. Mutations play a part in both normal and abnormal biological processes such as evolution, cancer, and the development of the immune system.
A mutation can occur anywhere in any chromosome, this is because they are caused by "random" processes. The vast majority of mutations have no impact on the organism (the amount of noncoding DNA in most chromosomes is larger than the amount of DNA in functioning genes, and some mutations while they change part of a gene do not change to protein it codes for at all) in which they occur and in multicellular organisms cannot pass on to the next generation (only mutations in the cells that make egg and sperm cells can be passed on).
You can be a carrier of a recessive gene as part of your genotype.
First of all, chromosomal mutations are gene mutations. Chromosomes can be thought of as lists of instructions for your cells to build life essential proteins and other basic functions. A chromosomal mutation occurs when a portion of a chromosome is changed in some way. A portion may be removed, flipped, or part of another chromosome may be inserted. In many cases this will have no effect on cell function, as the mutation occurred in an ignored portion of the chromosome. In most cases where the mutation occurs in an important portion of the chromosome, the cell simply dies. Cancer occurs when the mutation, instead of killing the cell, causes the cell to multiply, and consume body resources more faster than normal cells, overwhelming them.
no. what you described is a gene. a mutation is a change in the DNA which can sometimes change a gene
False. A mutation refers to a change in the DNA sequence of a gene or chromosome, not the specific part of a chromosome that carries information about a trait.
A frameshift mutation, such as an insertion or deletion of nucleotides, can cause a shift in the reading frame of a gene during translation, leading to a premature stop codon. This results in a truncated protein that is much shorter than the original gene product.
The mutation theory is basically stating that mutation is one of the major factors that cause evolution. The mutation has to be a beneficial mutation, meaning that it has to help the survival of the organism that got the mutation. The mutation causes knew genes and diversity which can spread quickly throughout a population and eventually change the frequency of alleles (causes mutation) Remember the mutation has to be beneficial to the survival of the organism.
Jumping genes are a type of mutation known as transposition. This mutation involves the movement of genetic material from one part of the genome to another, potentially causing disruptions or changes in gene function.
Pseudogene.
Yes, gene mutation within a species is considered part of microevolution. Microevolution refers to small changes in the gene pool of a population over a short period of time, such as mutations, genetic drift, and natural selection, that can lead to changes in the traits of a population.
A point mutation causes a change in the amino acid sequence creating a new type of protein. The mutations are categorized functionally as nonsense, missense and silent mutations.
none because its all in the DNA . trust me i know because i did a sciece fair poject on it and got 1st place!

Gene mutations may occur in at least three Ways: they can be inherited from a parent, or acquired during a person's lifetime - See Epigenetics - or acquired during a person's lifetime - see Strontium 90.
No, Marfan syndrome is not a chromosomal abnormality. It is a genetic disorder caused by a mutation in the fibrillin-1 (FBN1) gene, which affects the body's connective tissue. This gene is located on chromosome 15.
