What is an enzyme?.....
Analogy of Cell wall
Answer:
In school, I was taught that it is like a bouncer who controls who enters and exits the club because the cell membrane controls what is able to permeate into the cell. It’s good, but I like to think of it as a door.

The HeLa cancer call genome is vastly different from Henrietta’s normal genome. A gene transfer from the human papillomavirus 18 virus (HPV18) to human cervical cells created the original HeLa strain of cancer cells.
a) Describe the type of evidence scientists would need to justify this claim.
b) From this discovery, an HPV vaccination was developed. Without HeLa cells, this would not have been possible. Yet, these cells were taken for research without Mrs. Lack’s knowledge. Evaluate the pros and cons of designating biopsy cells as "free cells," cells that can be used without required patient consent.
Answer:
a. Sequencing the genome and transcriptome of these cells
b. Pros: these cells can be very useful in research (as in Henrieta case)
Contras: 1. patient's family may have inherited the same genetic defect from their common ancestors, thereby this information might be used for malicious people
2. Ethical issues
Explanation:
By using genome sequencing technologies it is possible to determine the nucleotide sequence of the genome (DNA) and their transcriptomic products (i.e., RNAs, especially mRNAs) obtained from a particular cell type. Therefore, these technologies can be used to compare the genome of cancer cells and Henrietta’s normal genome.
HeLa cells have been very useful in pharmaceutical research. These cells have been used in cancer research, in the development of vaccines (e.g., polio vaccine and HPV vaccine), Parkinson's Disease, etc. Moreover, the use of cells without required patient consent may affect the patient’s family by exhibiting information about the genetic conditions of multiple generations of this family, which might be considered unethical and lead to problems associated with the malicious use of this information.
HeLa Cell
It is the first human immortal cell line.
a). The scientist took a tissue sample from a patient named Henrietta Lacks. She was a cervical cancer patient.
Now when the scientist observed the cell sample in the laboratory, they saw that cell was growing indefinitely, i.e. 'immortal'.
So, they named it the HeLa Cell.
Later, the scientist found many copies of HPV-18 (Human Pappiloma Virus-18) in these HeLa cells which is a strain of HPV.
These strains has caused cervical cancer in Henrietta Lacks.
b). The Pros
It could not have claimed if any medical negligence would have occurred.We can overcome the false perception of the patient.The research could be progressed without any interruption from the patient.The Cons
If the consent of the patient was not taken then there would have been legal issues as well as ethical issues.Also, the law orders to stop the research without patient's consent.Without the right patent, the commercialization of the cells would begin.Learn More :

Which of the following normally leads to the production of functional messenger RNA in eukaryotic cells?
Answer: The removal of portions of RNA known as intervening sequences (introns)
Explanation:
The removal of portions of RNA is known as intervening sequences (introns).
What is the process of splicing?In order to enable the translation of mRNA into a protein, RNA splicing puts together the protein-coding regions (exons) and cuts out the intervening, non-coding segments of genes (introns) from pre-mRNA.
Intron sequences are cut out and exon sequences are joined during the splicing process.
As RNA matures, introns are cut out via RNA splicing, which means that they are not expressed in the resulting messenger RNA (mRNA) product.
In contrast, exons continue to be chemically bound to one another to produce mature mRNA. Exons are expressed sequences, whereas introns can be thought of as intervening sequences.
Therefore, the removal of portions of RNA is known as intervening sequences (introns).

What happens to the cell at the beginning of interphase?
Answer:
Explanation:
Early interphase is called the G1 phase of the cell cycle. G1 is the time during which a cell grows to its proper size by making more cytosol, the liquid inside a cell. An increase in cell size means the cell must make more protein and membranes. ... Cells that mature and never divide again stay in the G0 phase.

what a Lunar Phase ?
Answer:
It’s something like The lunar phase or Moon phase is the shape of the Moon's directly sunlit portion as viewed from Earth. The lunar phases gradually change over a synodic month as the Moon's orbital positions around Earth and Earth around the Sun shift
Answer with Explanation:
A lunar phase is also known as a "moon phase." This refers to how we see the Moon in different shapes as it is reflected back to Earth. Such reflection depends on the portion of the Moon that is illuminated by the sun. This explains why the amount of moon that we view from Earth changes over time.
It consists of 8 phases: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter and Waning Crescent.
