The relationship between a gene and a messenger rna is that .

mRNAs are made from genes

Explanation:

Messenger RNA (mRNA) is formed with the process of transcription.  

During the process of transcription, double stranded DNA which contain genes are converted into mRNA with the help of enzyme RNA polymerase, so, mRNA are made from genes.

The single stranded mRNA which corresponds to the genetic sequence of a gene allows the ribosome to produce protein (Translation).

Hence, the relation between mRNA ns genes is that mRNA ar emade from genes.

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
