Give 3 reasons why plasmids are considered ideal vectors.
Answer:
Self-replicating: Plasmids contains origin of replication and hence they are able to multiply by themselves independently of the chromosomal DNA. They maintain their number in progenies.
ii) Low molecular weight: Plasmids have low molecular weight which makes them easy to handle and hence can be present in multiple copies.
iii) Multiple Cloning Sites: This is a site on plasmid which has recognition sites for many restriction enzymes.
iv) Selectable Marker: Plasmid has certain genes which help in identifying the transformed cells. For example, antibiotic resistance genes.
v) High copy number: Due to low molecular weight of plasmids, they are present in multiple copies. High copy number plasmids are require to produce large quantities of the recombinant DNA.
vi) Host range: Plasmids used as coning vectors have narrow host range so that transmission of these plasmids to other organism in environment is avoided.

anaphase- separated by spindle fibers and nuclear membrane regenerated
cytokinesis- splitting of cytoplasm
5. a) The human body produces hundreds of different enzymes. Why can't one type of enzyme be used
everywhere in the body? (4 points)
b) Pepsin is an enzyme in the stomach that helps break down proteins. What problems would you expect a
person to have if his or her stomach did not have enough pepsin? (2 point)
a) A single type of enzyme could not be used in every region of the body because the body is not a single celled organism, it is a multicellular organism and each cell needs special and specific care in order to function.
A single type of enzyme could not control all the different systems of the body. Different enzymes and specialized cells have the responsibility to carry out specific functions so that the body can properly operate. One type of enzyme could not manage the excretory, digestive, reproductive, skeletal systems etc as these regions of the body require distinct attention and assistance to keep the body regulations active and to maintain proper health.
b) Problems expected of someone who lacks pepsin would be a protein deficiency. This would be present by way of weak and brittle bones and overall immuno compromised health.
Another problem expected would be stunted growth and development. As an individual is not receiving the right and recommended amount of digested protein, their bodies will lack the nutrients to properly grow as they age.

Why is rna incorporated into the dna molecule during dna replication?.
Answer:
The use of this RNA as a template allows telomerase to extend the 3′ end of chromosomal DNA by one repeat unit beyond its original length. The complementary strand can then be synthesized by the polymerase α-primase complex using conventional RNA priming.

Remember, prophase, metaphase, anaphase, and telophase represent the stages of Mitosis - not
Interphase. Which stage of mitosis takes the least amount of time?
Answer:
Why is anaphase the shortest stage? The kinetochore microtubules shorten as the chromatids are pulled toward opposite poles, while the polar microtubules subsequently elongate to assist in the separation. Anaphase typically is a rapid process that lasts only a few minutes, making it the shortest stage in mitosis.

bats vs skunks. Who will win?
Answer:
Probably a bat because it has the advantage of flight something a skunk cant do. And yes although the skunk can shoot its gas all the bad has to do is avoid it right? But bats don't sense gas they sense sound since they don't have good vision. But they can sense heat and since a skunks defense is a huge pile of heat it can steer clear and beat the skunk.

Which organism in the food web above occupies multiple trophic levels?
Show Your Work
Answer:
F
Explanation:
It occupies both the third and fourth trophic levels. i.e
1st trophic level: Producer(plants)
2nd trophic level: Plant eaters (B & C)
3rd trophic level: Secondary consumers (E & F)
4th trophic level: Tertiary consumers (H & F) (they both feed on E which is a secondary consumer)
Thus F is both a secondary and tertiary consumer.
While doing field research, two scientists discover a new species of plant. They take the plant back to their lab to watch how it grows and reproduces. Soon, the plant begins to produce a small purple flower. Upon further investigation, the scientists discover that the plant's seeds contain two embryonic leaves. Which group could the plant belong to
A dicotyledonous plant is an angiosperm that produces flowers and their seeds contain two cotyledons. The new species belong to the dicotyledonous group.
What is an angiosperm?
Angiosperms are woody or herbal plants, with a wide diversity of biotypes. Among many other characteristics, we can mention the followings,
They have flowers that can be either hermaphrodites or unisêxual, usually protected by perianth leaves.
During fertilization, pollen grains get in touch with the ovule. They have double fertilization.
They produce seeds from ovules protected in ovaries or closed carpel cavities.
They can be either monocotyledonous or dicotyledonous since seeds have one or two cotyledons.
What are dicotyledonous plants?
Dicotyledonous are one type of angiosperms. Among many other characteristics, we can mention the followings,
Their seeds carry two embryonic leaves -cotyledons-.
They have a primary root from which many secondary roots emerge.
Their stem is ramified, and their leaves have a reticulated vein system.
