Answer:
Transposable elements are discrete segments of DNA that can be excised and reintegrated to another site in the genome, these can inactivate the gene in which they reside, cause chromosome breaks, and / or transpose to a new location within the genome.
Explanation:
Transposable elements are fragments of DNA that have the ability to jump from one part of the genome to another. While most of the DNA is always in the same place surrounded by the same neighboring pieces of DNA, mobile elements move from one place to another causing many changes or mutations. When a transposon moves through the genome, it can insert into a vital gene, disrupting its function, or into a location near vital genes, causing erroneous activation or inactivation.On the other hand, there can be chromosomal rearrangements due to transposons of the same family with complementary sequences that are separated in the genome and that by sequence homology match. This can lead to ectopic recombination. Large-scale rearrangements induced by mobile elements are considered a particular class of recombination events that influence genomic plasticity.

You now find new cells which contains 200 mM CaCl2 and 15 mM glucose. The cell membrane is permeable to Ca ions, impermeable to Cl- ions, impermeable to Na ions and impermeable to glucose. You transfer these cells into a solution which has 140 mM (NaCl) and 150 mM glucose. What happens to the cells after the solution and cell have come to equilibrium
Answer:
The correct answer would be - ions will move from solution 1 to solution 2 so the cell will shrink.
Explanation:
The concentration of CaCl2- = 200mM
CaCl2 dissociates in the three different ions in a solution and each has the same osmolarity
The concentration of glucose = 15 mM
So, the osmolarity of solution 1 would be:
3 × 200 + 15= 615 mM
Similarly, the osmolarity of the second solution would be
The concentration of NaCl = 140 mM
The concentration of glucose = 150 mM
NaCl dissociates in the two different ions in a solution and each has the same osmolarity
140×2+ 150= 430 mM
The solution has more concentration of ions than solution two so the movement of the calcium ion of the CaCl2- would be possible only and therefore, the cell in solution 1 will shrink.

The bacteria we are growing contain both chromosomal DNA and plasmid DNA. Both are circular, but they are different. In 3-5 sentences, discuss at least 3 differences between the chromosomal DNA and plasmid DNA found in our bacterial cells.
Answer:
Please find the explanation of the differences between chromosomal DNA and plasmid DNA below
Explanation:
As stated in this question, a bacteria cell contains both chromosomal or genomic DNA and an extra chromosomal DNA called PLASMID. They are both circular in shape but are different from one another in the following ways:
- Chromosomal DNA is larger in appearance than the plasmid DNA, hence, they differ in terms of size.
- Chromosomal DNA encodes all the information in the genome of the bacterial cell necessary for their growth and development while plasmid DNA encodes few additional beneficial characteristics such as antibiotic resistance, virulence etc.
- Chromosomal DNA is wrapped around histone proteins to form the chromosome structure but plasmid DNA is naked and not wrapped around histone proteins.

Peter's Grandma has very severe memory loss. Which of the following could she be suffering from?
A. Spina bifida
B. Quadriplegia
C. Epilepsy
D. Alzheimer's
Peter's Grandma with very severe memory loss is suffering from Alzheimer's.
What is Alzheimer?Alzheimer is a progressive disease that destroys memory and other important mental functions.
Alzheimer causes the brain cell connections and the cells themselves to degenerate and die, eventually destroying memory and other important mental functions.
Thus, we can conclude that, Peter's Grandma with very severe memory loss is suffering from Alzheimer's.

Which enzyme activate vitamin K in the liver and blocked by which drug?
Answer:
menadione
Explanation:
Vitamin K is a fat soluble vitamin that exists in two natural forms: phytonadione (K1: fye toe" na dye' one) which is derived from plant sources and menadione (K2: men" a dye’ one) which is derived from bacterial sources. Vitamin K is a cofactor in the photosynthetic electron-transport system in green plants, which are the major dietary source of vitamin K for humans. High levels of vitamin K1 are found in leafy green vegetables while vitamin K2 is found in meat, milk and butter. In humans, vitamin K is an essential cofactor in the gamma-carboxylation of glutamate residues of several clotting factors and anticoagulant proteins. Hope this helps!
g It has been proposed that integrin proteins undergo conformational changes when they bind to small molecules diffusing into the extracellular matrix. Because integrins are transmembrane proteins, a change in their conformation can be transmitted across the membrane to the portion of the protein that interacts with intracellular structures. What biological role does this allow integrins to play in a cell's function within a multicellular organism
Answer:
Cell-cell communication
Explanation:
Integrins are heterodimeric transmembrane receptors that facilitate the adhesion to the cell-extracellular matrix by attaching the cytoskeleton to this matrix. Moreover, integrins also help the cells bind with other cells. Integrins are responsible for the communication between cells and thus control tissue structure. These receptors are responsible for the attachment of fibroblasts to collagen, as well as the attachment of fibroblasts to fibronectin. It is also important to highlight that the binding of integrins with their corresponding ligands activates signaling pathways that control diverse cellular processes including, among others, cell growth, cell development, cell migration, phagocytosis, etc.
