They happen after the organism has been born, and often lead to tumours and cancer (caused by carcinogens). Other types of mutations can be caused by mutagens, which mutate the DNA of a cell. It doesn't affect the DNA of every cell in the organism/ reproductive cells, so isn't passed on to offspring
What else can I help you with?
Where do you expect genetic differences between cells to arise from mitosis or from meiosis?
That is a good question. In mitosis, you don't get regular genetic variation but chance mutations can occur. In meiosis with fertilization, you get pairing of DNA from different hosts on a regular basis. I would choose the latter.
What is cell mutation?
In prokaryotes cell transformation is an alteration of the cell from the uptake, genomic incorporation, and expression of foreign genetic material.In eukaryotes this is called transfection. Transformation in eukaryotes is reserved to describe an alteration of the cell that results in a tumor cell phenotype.
What causes mutations in bacteria?
Pretty much the same process that causes mutations in any organism. The replication of the genetic code is not perfect and copying mistakes are made where one bases is substituted for another, or a whole string of bases is shifted in a frame shift. Google ' mutation. '
Cells in a cell culture all have the same genetic material because they are A. vectors B. plasmids C. hybrids D. clones?
Cells in a cell culture of similar genetic material are called clones. vectors can be the carriers of viruses . Plasmids are the extrachromosomal genetic material. Hybrids are the cells produced from the combination of two cells.
Can mutations that occur in somatic cells be passed on to an organisms offspring?
If the mutation happens in the germ cells, only then it wil be passed on to the offsprings. But, if it happens in some other cell, then it won't be. Such a mutation is Superficial. Like, if we cut the tail of a mouse, no change occurs in the germ cells. So the next generation will still be born with a tail.
What is gametoclonal variation?
Gametoclonal variation refers to genetic variation that arises from the in vitro culture of gametes, which are reproductive cells such as sperm and egg cells. This variation can result from mutations or rearrangements of the genetic material during cell division in the cultured gametes, leading to new genetic combinations. Gametoclonal variation can be used in plant breeding to generate novel traits or genetic diversity.
Does cancer result from genetic mutations-?
Mutating Cells can be a source of Cancer, but not necessarily. All mutating cells do not cause Cancer.
Where do you expect genetic differences between cells to arise from mitosis or from meiosis?
That is a good question. In mitosis, you don't get regular genetic variation but chance mutations can occur. In meiosis with fertilization, you get pairing of DNA from different hosts on a regular basis. I would choose the latter.
Is the only possible source of new genetic material?
mutations recombination/crossing over in mammals
Body cell mutations cannot be passed on to offspring. This is because body cells do not contribute genetic material to?
reproductive cells. Only mutations in germ cells, which are responsible for passing genetic information to offspring, can be inherited.
What causes DNA variation in organisms?
Mutation of the genetic code causes DNA variation in organisms. For example, during DNA replication, one nitrogen base may be substituted for another, or an extra base can be added, or a nitrogen base can be skipped. If any of these mutations occur during the formation of gametes (sex cells), then the offspring that receives the mutation may have a genetic disorder.
Do Organisms produced as a result of binary fission exhibit a great deal of genetic variation?
Organisms produced through binary fission do not exhibit a great deal of genetic variation because this process involves a single parent cell dividing into two identical daughter cells, meaning they have the same genetic information. However, mutations can occur during the process, leading to some genetic diversity.
What are the three necessary characteristics of the hereditary molecule in cells?
The three necessary characteristics of the hereditary molecule in cells are: the ability to store genetic information, the ability to replicate and transmit this information accurately during cell division, and the ability to undergo mutations that provide genetic variation for evolution.
Are all mutations passed on to your children?
No, not all mutations are passed on to children. Mutations can occur in the DNA of reproductive cells (eggs and sperm) and if they are present in those cells, they can be passed on to the next generation. However, most mutations occur in non-reproductive cells and are not passed on to offspring.
What changes occur in the genes of sex cells?
In sex cells, or gametes, genetic changes occur primarily through two processes: meiosis and genetic recombination. During meiosis, homologous chromosomes undergo crossing over, leading to the exchange of genetic material between them, which creates genetic diversity. Additionally, mutations can occur in the DNA of sex cells, which may be passed on to offspring. These changes contribute to the genetic variation essential for evolution and adaptation.
What is the major source of new alleles in natural populations?
Mutations are the major source of new alleles in natural populations. Mutations are random changes in the DNA sequence that can create new genetic variations. These variations can then be passed on to future generations through reproduction, contributing to genetic diversity in a population.
How would drugs affect the genetic variation of the cells?
it would get them high
