DNA. We have heard that we are a product of our DNA. But where is it? How do we "get" our DNA? It is passed to us, from our pare
nts, but in what form? Several vocabulary words associated with inheritance are used interchangeably and sometimes, incorrectly. Let's see if you can clear this up for someone just learning about inheritance and cell structure.
<span>The answer is: This is a cell (B) with a nucleus (C) containing DNA (A). The DNA is organized into chromosomes (D). A section of the chromosome that codes for a trait is called a gene (E).</span>
During cell division, genetic material of parents in the form of genes and alleles is transferred to the offspring. DNA is responsible for encoding genetic information.
Explanation:
DNA consists of genetic information in the form of nucleotide which are nothing but chemical compounds composed of phosphate, sugar and four nitrogenous bases. DNA consists of two chains made up of nucleotide with alternate sugar and phosphate group.
All living beings exhibit genetic information forms their ancestors and hence they carry genetic material from two parents in case of sexual reproduction and one parent in case of asexual reproduction. Genes carry allele which is responsible for expressing any physical trait.
