Answer:
The enzyme responsible for separating the two strands of DNA in a helix so that they can be copied during DNA replication.Explanation:
It must be folowed by the cytoplasm. Once it pops out everything will be smooth.
Answer:
The correct answer would be C) The Calvin cycle takes place only in the chloroplast.
The major difference between photosynthesis and respiration is that photosynthesis takes place only in plants while respiration takes place in all the living organisms including plants and humans.
Green plants and few bacteria contain special organelle called chloroplast which enables them to perform photosynthesis.
Hence, Calvin cycle (light independent phase of photosynthesis) takes place only in plants that too in chloroplasts.
In contrast, Krebs cycle usually takes place in mitochondria in both plants and animals and glycolysis takes place in the cytoplasm of the cell.
The electron transport chain takes place in mitochondria in animals whereas in plants it takes place in both mitochondria and thylakoid membrane.
