They ALL have DNA made of the same basic components, but the way that it's organized is different (circular in prokaryotes, linear in eukaryotes, typically). Prokaryotes and eukaryotes have different ribosomes and eukaryotes have membrane bound organelles.
Cephalocaudal pattern of motor development
Answer:
A gene mutations can be defined as the permanent alteration in the sequence of the DNA that makes the gene. Gene mutation may give rise to genetic variations or from the genetic recombination. These variations are known to alter the gene activity and the function of the protein. These variations in the protein or gene activity give rise to different traits in an organism.
If the trait is beneficial and helps the organism to survive and reproduce, such variation is likely to be passed to the next generation.
