Answer:The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go through some processing steps before translation into proteins.
Explanation:

<u>The four types of interactions in communities are:</u>
- Mutualism
- Parasitism
- Commensalism
- Competition
<u>Definition of each interaction:</u>
<em>Mutualism: </em>
The type of interaction in which both the species involved are benefited, it is called mutualism.
<em>Parasitism:</em>
The type of interaction in which one species is benefited, whereas the other is harmed, it is called parasitism.
<em>Commensalism:</em>
The type of interaction in which one species gets benefited without harming or providing benefits to others is called commensalism.
<em>Competition:</em>
The type of interaction in which both species lose is called competition. It is opposite of mutualism.
<u>Symbiotic relationship:</u>
It refers to the type of interaction in which lastly one species gets benefited. The type of interactions such as <em>mutualism, commensalism, and Parasitism </em>are considered as symbiotic relationship.
Answer:
Many small organisms can be preserved within these layers of sediment through time. The changing abundances of these fossils through time can tell us whether a change in the environment or climate was gradual or abrupt. Studying fossil pollen and other fossils helps scientists to learn more about climate change.
