What is a cancer cell line?

Essentially, a cancer cell line is made up of cancer cells that keep diving and growing over time, under certain conditions in a laboratory. This is used to research cancer and test on it to gather data, and can be significantly beneficial by being applied.

What is cancer?

Cancer is a disease where abnormal cells divide uncontrollably and destroy body tissue. There are many types of cancer, the most common being: breast cancer, prostate cancer, and basal cell cancer. Statistically, lethal cases are more common in men than women. In all types of cancer, some of the body’s cells begin to divide without… Continue Reading

What is the cell cycle?

Often referred to as the “cell-division cycle”, this describes the events that take place in a cell, leading to its division and duplication of DNA to produce two “daughter cells”. It can be quite complicated when explored in-depth, but its main steps are: Interphase (Chromosomes are extended and used in the G1, S, and G2… Continue Reading

What is apoptosis?

Simply put, apoptosis is the death of cells that occurs as a normal and controlled part of an organism’s growth or development. This can be compared to necrosis, which is the opposite: it is when a cell is damaged by an outside force. Apoptosis is, in essence, a cell committing suicide. It is controlled and… Continue Reading

What is the difference between plant and mammalian cells?

Plant cells and mammalian cells do share many similarities, but they each have key differences and functions that make them so respectively individual. Both are eukaryotic, therefore similar in structure, but plant cells are larger, sometimes significantly. Mammalian cells are typically round and irregular in shape, while plant cells are fixedly rectangular. A plant cell… Continue Reading

Cell structure

Cells have many vital parts that keep it functioning, and each has a very important role. The cell membrane is found in both animal and plant cells, and its primary function is to regulate what goes in and out of the cell. Chloroplast is only found in plant cells, and it captures energy from sunlight.… Continue Reading

Cell membrane

In essence, it is the semipermeable membrane surrounding the cytoplasm of a cell. All cells are contained by a cell membrane that keeps the pieces inside. The cell membrane is not a solid structure. It is made of millions of smaller molecules that create a flexible and porous container. Proteins and phospholipids make up most… Continue Reading

What is RNA?

RNA is known as ribonucleic acid is a nucleic acid, and is one of the three major biological macromolecules that are essential for all known forms of life. It is an important molecule with long chains of nucleotides. A nucleotide contains a nitrogenous base, a ribose sugar, and a phosphate. The structure of RNA nucleotides… Continue Reading
