What type of chromosomal abnormality can lead to multiple copies of a gene, some of which can incur mutations that can lead to t
koban [17]

A trisomy is a chromosomal condition characterized by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46.

Trisomy means the presence of an extra chromosome in some or all of the body's cells. This results in a total of three copies of that chromosome instead of the normal two copies. For example, Down syndrome (trisomy 21) is caused by having three copies of chromosome 21 instead of the usual two copies.

This genetic condition is the result of a genetic mutation where your cells don't divide as they should. You can't prevent this abnormality from happening during cell division.

aleksley [76]

Ribonucleic acid (rna) and additional deoxyribonucleic acid (dna) surrounds genes. in a process called methylation, they enhance, silence, or alter genetic instructions.

<h3>What is DNA methylation?</h3>
  • Adding methyl groups to the DNA molecule is a biological process known as DNA methylation. Methylation has the ability to change a DNA region's activity without changing the sequence.
  • When DNA methylation takes place at a gene promoter, it frequently decreases gene transcription.
  • DNA methylation plays an important role in a number of critical processes in mammals, including aging, cancer, X-chromosome inactivation, genomic imprinting, and transposable element repression.
  • The majority of eukaryotic genomes contain DNA methylation, a dynamic epigenetic alteration. It is well recognized to cause a high rate of CpG to TpG mutations.
  • However, nothing is known about the connection between the rate of germline mutation and the dynamics of methylation during germline development.
