A. mitosis produces 2 genetically identical diploid daughter cells from one parent cell.
DNA strands within each chromosome breaks in the exact same location, leaving two free ends then crosses over into the other chromosome and forms a connection called a chiasma!
<span>The genetic code is redundant, that means same genetic code is present in multiple times, in each cell. it acts as "nature's safety net" because if we happen to lose a part of our body or genetic material, it can be regenerated using the remaining part which contains the same genetic code.</span>
In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.
