Why would it be more harmful for a mutation to occur in a reproductive cell than a body cell?
If there is mutation in reproductive cell then the zygote will be defective. Then all the body cells will carry the defect as there is division of cells by 'Mitosis'. So whole baby will be defective. If body cell is defective then body immunity will eliminate the same. Fortunately most of the abnormal zygotes are washed in 'normal' menses and lady do not know that she has miscarriage. In first trimester miscarriages most of them are with abnormal chromosomes.

How would a mutation affect the next generation?
A mutation can be passed on to the next generation if it occurs in the germ cells (sperm and egg cells). The impact of the mutation on the next generation can vary depending on whether it is beneficial, harmful, or neutral. Over time, mutations can contribute to genetic diversity and evolution in a population.
Why wouldn't a mutation in a non-reproductive cell be passed on to offspring?
If this mutation isn't present with a gamete cell, then it can not be passed onto the offspring. A non-reproductive cell would be cells that are highly organzied such as nerve cells or brain cells.
What could be a harmful mutation?
A harmful mutation is one that can disrupt the normal functioning of a gene, leading to the production of a non-functional or altered protein. This can result in diseases or disorders, such as cancer, cystic fibrosis, or sickle cell anemia. Harmful mutations can also impact an individual's ability to survive and reproduce.
Which type of mutation will probably have a larger effect A point mutation or a frameshift?
Both types of mutation have the potential to cause a large effect.In general, a frameshift mutation is more likely to cause a large effect. This is because it shifts the 'reading frame' - so that all of the subsequent codons (groupings of 3 bases that are read to determine which amino acid will be added) will be changed.A point mutation is when a single base is replaced. This can either result in the same amino acid being added to the protein being synthesised (a silent mutation), a different amino acid being added (a missense mutation) or in a STOP codon (a nonsense mutation).If a point mutation causes a premature STOP codon - this is quite likely to have a large effect on the protein.
Which mutation cannot occur in a tRNA encoding gene?
A mutation that changes the start codon of a tRNA gene is unlikely to occur, as that could prevent proper translation of the tRNA. Mutations that disrupt critical structural elements such as the anticodon loop or the acceptor stem are also less likely, as they would affect the tRNA's functionality.
When would mutation not be harmful?
Mutation would not be harmful if the mutation allowed an animal to live longer. This may be the case if an animal that is not normally albino is born albino in a place that gets a lot of snow.

How could a mutation be helpful rather than harmful?
a bad mutation would be if your DNA coded for you not to be able to digest fats. you would starve to death.
Which do you suppose would be more harmful A mutation that changed the nucleotide sequence of an mRNA molecule or a mutation that changed the nucleotide sequence of a DNA molecule?
A mutation in a DNA nucleotide sequence would be more harmful than a mutation in a mRNA nucleotide sequence because it could cause the synthesis of multiple nonfunctional proteins in comparison to a mutation in a mRNA nucleotide sequence that would be less harmful because it would result in a few nonfunctional proteins.
Why wouldn't a mutation in a non-reproductive cell be passed on to offspring?

What kind of mutations do you think would be harmful to an organism?
The majority of mutations that organisms get are harmful or neutral. Cancer is an example of a harmful mutation. So are certain genetic diseases and deformities, like an extra set of limbs.
What would be the consequences for evolution if there were no reproductive variation?
There would be no adaptive change due to natural selection and only genetic drift due to random events and gene flow due to population mixing would occur. Alleles would change, but without reproductive variation speciation could not occur.

What might occur if a mutation reduced the water-repellent quality of suberin?
The apoplastic route of water travel would be allowed.
Why not all mutation cause cancer?
Many mutations are actually benign. They may occur in areas of DNA which don't code for anything, or a mutation may occur in a gene that isn't expressed (ie, isn't "turned on" and being used to make proteins) in that particular cell. Even when a mutation occurs in an expressed gene, it may still be benign since different codons can translate into the same amino acid. For instance, the DNA sequences 'GGA' and 'GGC' both code for the amino acid proline. This means that a mutation from 'GGA' to 'GGC' would still cause the same amino acid to be synthesized, and no bad effect would result. Even when a mutation is harmful, the result isn't always cancer. Many other diseases, such as hemophilia and Huntington's disease, are genetic and would have first come about as mutations. Cancer occurs when mutations happen in genes that control cell growth, division, and death.
