Question

Explain the importance of error in the DNA that take place during the reproduction. Class 10 plz answer relevantly otherwise I'll report it

Answer 1

$\large\underline\bold\purple{Importance\:of\:error\:in\:the\: DNA \:in\: Reproduction}$

• The chromosomes in the nucleus of a cell contain information for the inheritance of features from the parents to next generation in the form of DNA (Deoxyribo nucleic acid) molecules. So, the first importance of error in the DNA is that the characteristics of the parents organism are transmitted to its offsprings.
• When the DNA already present in the nucleus of a parent cell is copied by making more of DNA by certain biochemical reactions, then slight variations come in two copies formed. These slight variations in the copying of DNA molecules lead to slight variations in the offspring produced. Thus, another importance of error in the DNA copying is that some variations are produced in the offsprings during reproduction which form the basic for evolution.

$\large\underline\bold{Additional\: Information}$

• DNA is usually a double-helix and has two strands running in opposite directions. Each strand has a backbone made up of (deoxy-ribose) sugar molecules linked together by phosphate groups.
• Each sugar molecule is covalently linked to one of 4 possible bases (Adenine, Guanine, Cytosine and Thymine).
