Answer:
Explanation:
1. Topoisomerase is an enzyme helps in over winding Or underwinding of DNA during replication. Helps in the topological correction. So non-functional topoisomerase leads to tangled DNA and prevents replication..
2. Primases are the enzymes helps in the synthesis of short RNA sequences used as primers in replication. Non functional primase leads to no primer synthesis.
3. DNA Polymerase is an enzyme helps in the addition of new nucleotide to the growing strand in replication. Non functional DNA polymerase prevents the strand growing as no new nucleotides were added.
4. Helicases are the enzymes helps in the separation of double strands into single and helps in each strand to be copied. Non functional helicase leads to prevention of unwinding of strands and replication inhibition.
5. ligase is an enzyme that joins nicks(small gaps) in the DNA strand by creating ester bond. Non functional ligase leads to unjointed gaps of lagging strand.
6. Single strand binding proteins(SSB's) are the small proteins that binds to the single strands of DNA and holds them in a place not to get together while replicating. Non functional SSB's leads to parental strands come back together and prevents replication.
OOH I KNOW THIS ONE!!!
Tropical Forests (A)
Answer:
The correct answer will be option-F
Explanation:
The modern medical, molecular and genetic studies are performed on the model organism like C. elegans, mice and many others.
The reason for the studies is that the life span of these organisms is of short duration as compared to humans. These organisms are also made of cells which are sensitive to their environment as humans.
The studies have shown that this organism shows an orthology relationship in their genes due to the origin of the genes from the same ancestral genes.
Thus, option-F is the correct answer.
Answer:
both are correct!!
Explanation:
Carbon dioxide plays an important part in vital plant and animal process, such as photosynthesis and respiration. ... Plants and animals, in turn, convert the food compounds by combining it with oxygen to release energy for growth and other life activities. This is the respiration process, the reverse of photosynthesis.
