question 8
DNA is copied into mRNA during the process of <u>Transcription</u>
- <u> </u>Transcription is the process by which information in the strand of DNA is copied into new molecule of messenger mRNA.
- The mRNA formed is a complimentary to DNA strand whereby replace of C with G, and A with U and T with A.
Question 9
Translation occurs in the ribosome , the organelle responsible for building proteins.
- Ribosome are responsible for protein synthesis.
- They receive messenger RNA sent from the nucleus and build protein.
- translation has three steps that is
- initiation - ribosome assemble around the target mRNA.
- elongation- The tRNA transfer amino acid to tRNA corresponding to the next codon.
- Three phases of translation initiation polymerase bind to DNA strand and move along until the small ribosomal subunit binds to DNA.
It is true that rivers and streams are biodiverse ecosystems that are sensitive to change. Details about rivers and streams can be found below.
<h3>What is river and stream?</h3>
A river is a large and often winding stream which drains a land mass, carrying water down from higher areas to a lower point, oftentimes ending in another body of water, such as an ocean or in an inland sea.
On the other hand, a stream is a small river or a body of moving water confined by banks.
Rivers and streams are both freshwater ecosystems, hence, tend to respond to changes in their environment caused by anthropogenic activities.
Therefore, it is true that rivers and streams are biodiverse ecosystems that are sensitive to change.
