A genetic mutation is a change in a single or several base pair nucleotides in a DNA or RNA molecule. Mutations arise due to random errors during cell replication, as well as mutagens, which are mutation inducing physical or chemical agents.
Mutations which do not occur in sex cells are not passed on to the next generation. The mutation will only affect the individual. They could therefore have normal offspring.
A chromosomal mutation can occur either during the formation of the egg or sperm, or after fertilization when the zygote is forming. This means the mutation could have occurred in the parent's gametes, or during cell division in the early stages of embryo development.

During meiosis
nonsense mutation, missense mutation, frameshift muation, deletion or addition mutation
Such mutations are called point mutation or gene mutation.
Yes, if an enzyme necessary for polypeptide production is absent, the process may be disrupted. This could potentially lead to errors in translation, such as misincorporation of incorrect amino acids, which can result in a mutation in the polypeptide sequence.
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.
