D all of the above would be the correct answer
Answer:
Transcription and translation occur simultaneously in prokaryotes.
Explanation:
Prokaryotes lack membrane-bound organelles and therefore, do not have a nucleus. Transcription and translation occur in the cytoplasm. As soon as the required length of mRNA is being formed, ribosomes join it and start the process of translation. Prokaryotic genes lack introns. The primary transcript formed by transcription in prokaryotes does not undergo splicing.
On the other hand, the process of transcription occurs in the nucleus in eukaryotes while translation occurs in the cytoplasm. The primary transcript formed by transcription in eukaryotes undergoes modifications to remove introns and to add a poly-A tail and 5' cap. Post-transcriptional modifications and spatial separation of two processes in eukaryotes result in slower translation than prokaryotes.
Answer:
In eukaryotes, thousands of chemical reactions are able to take place in separate compartments called organelles.
Explanation:
Organelles are specific cellular structures that are the means of compartmentalizing the various functions that occur within cells.
Examples of organelles and their functions are:
- <u>Nucleus</u>: contains DNA and in it occur the replication of this molecule and its transcription into RNA.
- <u>Rough endoplasmic reticulum</u>: protein synthesis and conjugation of these molecules occurs.
- <u>Mitochondrion</u>: houses all oxidative phosphorylation reactions and the electron transport chain for ATP synthesis to occur.
The organelles are then the structures that allow the development of the multiple functions that a cell has.
The other options are not correct because:
- <em><u>Bacteria</u></em><em> is a prokaryotic organism.
</em>
- <em><u>Prokaryote</u></em><em> refers to simple organisms that lack organelles.
</em>
- <em><u>Proteins</u></em><em> are biomolecules that allow the structure and function of living beings.</em>
The difference between respiration and breathing is their functions. Breathing is when your body uses your lungs to inhale and exhale oxygen. Respiration is a chemical reaction where your body uses oxygen to eliminate or break apart Glucose so it could give you energy.
Hopefully this helps :)
