Answer:
1. Restriction enzymes
2. DNA ligase
3. ?
4. ?
5. ?
-------------------------------------------------
1. Identify your gene of interest (the one that produces human insulin in this case).
2. Isolate it from the rest of the DNA via restriction enzymes. Also extract a plasmid from a bacterium.
3. Use the restriction enzymes on the bacterium as well.
4. Join the cut plasmid and your gene of interest via mixing them and with the help of DNA ligase.
5. Insert the recombinant plasmid into a host cell. The plasmids are taken up by the bacterium by transformation.
6. Select for cells that have been transformed by linking the gene of interest to an antibiotic resistance gene or a report gene.

1. Agricultural Uses, we can insert disease-resistant genes into plants for example
2. We can amplify the DNA found at a crime scene to more easily trace down suspects
3. Medical Uses; we can more easily detect diseases and test for viruses (via amplification of blood samples).
<span>The difference in synthesis of lagging strand compared to synthesis of the leading strand is D) Synthesis of the leading strand does not involve RNA primers and Okazaki fragments. DNA polymerase adds nucleotides at the 3' end toward the 5' end in the direction 3' to 5'. The free end of the lagging strand is 5' so DNA polymerase cannot start from that end. The replication of the lagging strands is discontinuous and it involves RNA primers and Okazaki fragments. Synthesis of the leading strand is under control of DNA polymerase.</span>
Lever is responsible for supplying glucose to all parts as it contain polymer of glucose called as glycogen.
The answer is b)produces sugars
Answer:
Corn → rat → hawk → wolf
Explanation:
A food chain is a linear relationship that shows the feeding pattern of different organisms. The food chain portrays which organism located in one trophic level eats another. A forward arrow (→) is used to show that the organism after the arrow feeds on the organism before the arrow.
Every food chain starts with an organism called PRODUCER, which is capable of supplying the energy that is transferred from one organism to another. The energy moves along organisms called CONSUMERS as they feed on one another. According to this question, the below food chain shows the feeding relationship between four organisms:
Corn → rat → hawk → wolf
Note that, corn is the PRODUCER, while rat, hawk and wolf are CONSUMERS
