What inhibits the depolymerization of microtubules?
Drugs like taxol inhibit microtubule depolymerization by stabilizing the microtubules and preventing them from disassembling. Additionally, proteins like stathmin bind to tubulin dimers and promote microtubule depolymerization, so inhibiting their activity can also prevent depolymerization.
What is microtubules synthesis?
Microtubules are synthesized by polymerization of alpha and beta tubulin dimers. This process is tightly regulated by various microtubule-associated proteins. The dynamic nature of microtubules allows them to rapidly assemble and disassemble, contributing to their roles in cell division, intracellular transport, and cell shape.
What is disease caused by thymine dimmers?
Thymine dimers are DNA lesions that can be caused by exposure to ultraviolet (UV) light. When these dimers are not repaired, they can lead to mutations and potentially cause diseases like skin cancer.
Centrosomes are sites where protein dimers assemble into?
Centrosomes are sites where protein dimers assemble into microtubules during cell division. This helps in organizing the mitotic spindle, which is crucial for chromosome segregation. The centrosome is also involved in cell shape maintenance and intracellular transport.
What causes thymine dimers?
Thymine dimers are caused by exposure to ultraviolet (UV) radiation, which can lead to the formation of covalent bonds between adjacent thymine bases in DNA. This abnormal bonding distorts the DNA structure and can interfere with proper DNA replication and transcription.
What does the Microtubules do in an animals cell?
One function of microtubules is being conveyor belts inside of Cells. They move vesicles, granules, organelles and chromosomes via special attachment proteins. See MTOC - micro-tubule organizing centers. They also serve a cytoskeletal role. Structurally, they are linear polymers of tubulin which is a globular protein. These linear polymers are called protofilaments. The tubulin molecules are bead like structures. They form heterodimers of alpha and beta tubulin. A protofilament is a linear row of tubulin dimers.

What is these letters unscrambled deismr?
dermis dimers
Which type of physical mutagens produce tymine dimers?
Ultraviolet (UV) radiation is a type of physical mutagen that can produce thymine dimers. Thymine dimers are formed when adjacent thymines in the DNA strand become covalently linked, leading to DNA damage and potential mutations.
What wavelength of uv light causes thymine dimmers?
Ultraviolet light with a wavelength of around 260 nm causes thymine dimers to form in DNA. Thymine dimers are the result of two adjacent thymine bases on the DNA strand becoming covalently bonded after exposure to UV light.
Function of microtubules in cell division?
They move vesicles, granules, organelles like mitochondria, and chromosomes via special attachment proteins. They also serve a cytoskeletal role. Structurally, they are linear polymers of tubulin which is a globular protein. These linear polymers are called protofilaments. The figure to the left shows a three dimensional view of a microtubule. The tubulin molecules are the bead like structures. They form heterodimers of alpha and beta tubulin. A protofilament is a linear row of tubulin dimers.

How does the structure of microtubules allow them to apparently move from one location of a cell to another?
Microtubules are made of a dimer protein called tubulin. They grow in length by adding tubulin dimers, but they can also be disassembled. This process of assembly and disassembly makes the microtubule seem to move from one location of the cell to another.
After a long week of sunbathing on the beach what type of DNA damage might you be concerned about?
Thymine Dimers are what you should be concerned about...Thymine dimers cause kinks in DNAT-A T A~ |T-A T AThe paring of T to T causes the kink and the A-T connection is broken...

What effect Dimers molar mass determination volatile liquids?
I'm trying to figure out how it affects molar mass as well. However, I do know that it decreases the pressure which is in the denominator of the equation to find the molar mass once the ideal gas equation is manipulated. So i think that with the formation of dimers the molar mass would increase?
