Answer:
These bands represent different confirmation of DNA
Explanation:
pGLO DNA is a plasmid DNA that is used as a vector for genetic engineering. Plasmid DNA is found in supercoiled confirmation in vivo. The double helix forms extra twists to easily fit inside the cells. During isolation of plasmid from the cell, nicks can be introduced in the DNA due to harsh isolating methods or contamination by nuclease. As a result the supercoiled confirmation is changed into circular confirmation. It is bulkier than the supercoiled form and travels more slowly. When both DNA stands get cut at the same place, the DNA gets liner confirmation. In the end, supercoiled DNA runs the fastest on gel followed by linear DNA and then the circular DNA.

How is photosynthesis similar to cellular respiration? How do they differ?
Similarities Between Photosynthesis And Cellular Respiration
Similarities ...
→ Both involve in production of energy
→ Both involve the exchange of gases
→ Both the process takes place in cell organelle which was considered as endosymbiotic organism. They are chloroplast and Mitochondria, Photosynthesis takes place in Chloroplast where as respiration takes place in mitochondria.
→ At critical condition both have alternate pathway.
Differences...
→Photosynthesis takes place in chloroplast, where as respiration takes place in mitochondria.
→Photosynthesis involve production of carbohydrate and respiration involve breaking of carbohydrate.
→ Photosynthesis occur only during presence of sunlight where as respiration occurs all the time.
→ In photosynthesis process Oxygen is released where as in respiration Oxygen is utilised.
These are the main differences between Photosynthesis and respiration.
Answer:
The lytic cycle results in Immediate death of host cell.
Explanation:
- Lytic cycle is followed by virulent phages.
- Lysogenic cycle as well as lytic cycle are followed by temperate phages.
- During lytic cycle the host cell is lysed and new viruses are released very quickly .
- During lysogenig cycle, the viral genome integrates into the host genome and creates a prophage. When the infected cell replicates the prophage also replicates. Later at some time the prophage enter the lytic cycle.
- The main difference between the lytic and lysogenic cycle is, lytic cycle involves the lysis of the host cell while lysogenic cycle does not involve lysis of host cell.

have a difficulty of keeping koala bears alive because Koala bears are
susceptible to viral infections. There is a virus that is present to Koalas
which is called the Koala retrovirus. Koala retrovirus makes a Koala bear more
susceptible to infections and even cancer. </span>
