A climax community

Explanation:

A climax community is a relatively stable community in which the component species are in equilibrium with one another.

Ecological succession involves a gradual change of the species composition structure of a community over a period of time.

<em>Depending on the initial state of a community, the species composition keeps changing from pioneer species of a completely new habitat in primary succession through secondary succession and, in the absence of disturbance, to a stable community which is referred to as a climax community.</em>

Tamiku [17]

Answer:

AUG, ribosome, initiation, translation

Explanation:

The transfer of information from DNA to RNA to protein is called Central Dogma. The formation of protein from mRNA is translation. The translation begins with initiator codon AUG in mRNA. The ribosome small subunit (30s) binds to the RNA. The tRNA binds and then large subunit (50s) attaches with mRNA.  

Thus, reading from 5’ to 3’, this RNA product has the sequence <u>AUG.</u>  It binds to the small subunit of the <u>ribosome.</u> It is joined by the large subunit, completing the <u>initiation</u> stage of the process of <u>translation</u>.
