This process is called replication and happens in mitosis and meiosis.
Cloning
DNA synthesis or DNA replication
Transcription--making an RNA template from the DNA strand copy site
Replication is the process that makes an exact copy of a cell's DNA.
a mutation
Making a copy of DNA is called semi-conservative replication. It is a biological process which takes place in the genome of a cell.
When an error occurs in making a copy of DNA, we call it a mutation.
Mutation
It is important for cell to copy DNA without making mistake because the DNA contain genetic code in the form of nucleotide base pair sequence, if those sequence get wrong then the DNA code for wrong gene i.e. there will be a mutation which can be lethal or dangerous.
chimera
Deoxyribonucleic Acid
Ribonucleic acid
