Virus Cell Structure

Virus Cell Structure

A virus is a tiny, infectious particle that can reproduce only by infecting a host cell. Viruses are much smaller than bacteria and consist of a single- or double-stranded nucleic acid (DNA or RNA) surrounded by a protein shell called a capsid. Some viruses also have an outer envelope composed of lipids and proteins.

Key Components of a Virus

1. Nucleic Acid Genome: A virus is made up of a DNA or RNA genome. This genome is the genetic material of the virus and contains the information needed for the virus to replicate.

2. Protein Capsid: The genome is enclosed within a protective protein coat called a capsid. The capsid is made from proteins that are encoded by viral genes within their genome. The shape of the capsid may vary from one type of virus to another.

3. Lipid Envelope: Many animal viruses also contain a lipid envelope. The envelope is made from portions of the host’s cell membrane. It surrounds the capsid and helps protect the virus from the host’s immune system. The envelope may also have receptor molecules that can bind with host cells, making it easier for the virus to infect the cells.

Types of Viruses Based on Structure

1. Helical Viruses: Helical capsids are made up of a single type of protein subunit stacked around a central axis to form a helical structure. This arrangement results in rod-shaped or filamentous virions. An example of a helical virus is the tobacco mosaic virus.

2. Icosahedral Viruses: Icosahedral capsid symmetry gives viruses a spherical appearance at low magnification, but the protein subunits are actually arranged in a regular geometrical pattern. They are not truly spherical.

Virus Reproduction

Viruses reproduce by infecting their host cells and reprogramming them to become virus-making “factories”. They “commandeer” the host cell and use its resources to make more viruses.

Conclusion

Viruses are unique entities that straddle the line between living and non-l

Most people know that the primary function of the kidneys is to eliminate waste products from the body by flushing them out with urine. However, did you know that there are at least 6 other fabulous functions you should thank your kidneys for?
A a Kidney Function Profile, is used to test the health of the kidneys. The nephron is the filtration unit of the kidney. It is the basic structural and functional unit of the kidney and cannot be seen by the naked eye. Each kidney has about 1 million nephrons. The walls of the nephron are made of a single layer of epithelial cells.

Cancer develops when cells in the body multiply out of control. Blood contains three kinds of cells: red cells, white cells, and platelets. Any of these kinds of cells can develop into cancer cells. So instead of a tumor (a clump of cancer cells) developing, such as in lung cancer, the tumor cells are spread throughout the blood system of the body.

Cyclacel Cell Cycle Diagram

The phases are: 1. G1 (gap1) phase 2. S (synthesis) phase 3. G2 (gap 2) phase 4. M (mitosis) phase. Cell Cycle: Phase # 1.
Our strategy is to build a diversified portfolio of novel drug candidates to address areas of high unmet medical needs. Cyclacel is a pioneer in the field of cell cycle biology. Our vision is to improve patient healthcare by translating cancer biology into medicines.
The G 1 phase is set in immediately after the cell division. It is characterised by a change in the chromosome from the condensed mitotic state to the more extended interphase state and by a series of metabolic events leading to initiation of DNA replication. G, phase of cell cycle varies in length from cell to cell within the same cell population.

Mitosis. process cell division. Mitosis is the process by which our bodies replace cells. Daughter cells have identical chromosomes to parent cell, genetic Diagram of the Cell Cycle.
Types of Cell Division There are two distinct types of cell division out of which the first one is vegetative division, wherein each daughter cell duplicates the parent cell called mitosis. The second one is meiosis, which divides into four haploid daughter cells. Mitosis: The process cells use to make exact replicas of themselves.
The simple form of division displayed is binary fission. No chromosomes are sorted, or reduced. The organelle is simply enlarged and split in half, with the DNA that controls it being duplicated as well. 3. Evolution depends on the successful replication of DNA.

Cancer Stem Cells Diagram

Cancer stem cells ( CSCs) are cancer cells (found within tumors or hematological cancers) that possess characteristics associated with normal stem cells, specifically the ability to give rise to all cell types found in a particular cancer sample.

Abstract The cancer stem cell hypothesis posits that tumor growth is driven by a rare subpopulation of cells, designated cancer stem cells (CSC).

In the cancer stem cell (CSC) model, only the CSCs have the ability to generate a tumor, based on their self-renewal properties and proliferative potential. The cancer stem cell model, also known as the Hierarchical Model proposes that tumors are hierarchically organized (CSCs lying at the apex (Fig. 3).)

Human Cells

Human Cell Diagram, Parts, Pictures, Structure and Functions. The cell is the basic functional in a human meaning that it is a self-contained and fully operational living entity. Humans are multicellular organisms with various different types of cells that work together to sustain life.
Cells in the human body number in the trillions and come in all shapes and sizes. These tiny structures are the basic unit of living organisms. Cells comprise tissues, tissues make up organs, organs form organ systems, and organ systems work together to create an organism and keep it alive.
They form the body’s structure, take in and transport nutrients from foods to the host, convert nutrients to energy, and carry the genetic materials of the body. The cell, though extremely minute does have different parts on it. (1, 2) Diagram 1: The anatomical presentation of the human cell. How many cells are in the human body ?

Heart Cell Diagram

A detailed explanation of the heart along with a well-labelled diagram is given for reference. The upper two chambers of the heart are called auricles. The lower two chambers of the heart are called ventricles. The outer layer of the heart wall is called epicardium. The middle layer of the heart wall is called myocardium.

This diagram of the heart will not only give you details about the various parts, but will also explain the importance of keeping your heart healthy. Human heart is slightly bigger than the size of one’s fist. It is situated at a very safe place which is between the cage bones, i.e., in the center of the chest.

When we look a bit closer at cardiac muscle, we can see that it is arranged in sheets of cells, which are connected to each other in a lattice-work fashion. Where two cells meet a specialized junction called an intercalated disc locks the two cells into place.
