How are gene and protein sequences used to classify organisms?

"Genes code for proteins and each organism has different genes."

Explanation:

"Sequences of genes are used to identify differences and similarities between organisms. So it can be used to identify related organisms, because they show differences between species.

DNA acts as set of instructions for building an organism, because it contains the genetic instructions to make for proteins. Genes are made of DNA and each one codes for a different protein. In that way, different types of organisms can all be differentiated through their genes.

This is because the translation of proteins from DNA is guided by a universal code. It means, the same codons codes for the same amino acid across all species."

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
