Life Without Cells for the MDCAT Biology Test. Biology study points for the MDCAT. MDCAT Biology acellular unit review. Once you understand the details, it’s time to really study Acellular Life for FSC Biology (1st-year).
You don’t want to waste your time studying things that might or might not be on the test. Instead, you want to be sure that what you’re studying will be on the test. Make sure you know these 5 key points to help you ace FSC Biology’s Acellular Life topic and study more efficiently!
Acellular Life Key Points:
A cell’s life cycle depends on what type of cell it is and where it is in the body. Here’s an overview of the stages and processes that occur during cell development. From the moment of conception to when the new cells take on their designated function in the body. And grow into full-fledged adult cells capable of performing specific functions. There are three basic steps in cell growth, that are: 1) replication, 2) specialization and 3) degeneration or death.
Example Key Points:
We have collected some important Acellular life key points and crammed notes for MDCAT Biology entry test preparation. The list of main key points is given below.
- A virus is an extremely tiny parasite that can only reproduce if it is within a living being.
- Viruses can infect all types of life forms, from animals and plants to
microorganisms, including bacteria and archaea. - Viruses lie on the borderline between living things and nonliving things.
- Viruses are considered living because viruses possess DNA or RNA.
- Viruses have the ability to reproduce, and can also undergo mutation and genetic recombination.
- Among nonliving characters, viruses are subcellular or have no cellular structures.
- They do not respire or excrete and can be crystallized and stored in much the
same way as chemicals. - Viruses can be broadly classified based on morphology and the type of host they infect.
- On the basis of morphology, there are 3 classes of viruses; Le. Spherical virus (poliovirus), tadpole-shaped virus (bacteriophage), and rod-shaped virus (tobacco mosaic virus).
- 10. On the basis of the host, viruses are.
Additional Key Points For MDCAT Biology Portion:
- Animal-like viruses are the parasites of animals and human beings and cause diseases in them.
- Common diseases in man are polio, smallpox, measles, mumps, influenza, etc.
- Plants viruses are parasites of plants and cause diseases in them.
- Bacteriophage (phage) is a parasite only on bacteria.
- Bacteriophages are obligate intracellular parasites that multiply inside bacteria by making use of host biosynthetic machinery.
- The size of the phage ranges from 24-to 200 nm in length.
- All phages contain head (capsid) structures that can vary in size and shape i.e. some are icosahedral (20 sides) others are filamentous.
Detailed Key Points For Biology Entry Test:
- The tail of phage is a hollow tube through which nucleic acid passes during an infection- do not even have a tail ‘”
- The size of the tail can vary and some phage
structures. late and one or more t 1 - In more complex phages like T4 have a base P, at
fibers attached to it, which are involved in the attachment of phage to the bacterial cell. - Not all phages have base plates and tail fibers, m these instances other structures are involved in the attachment of the phage particle to the. bacterium protein.p17.
