What Is The Hub In Centrioles Connected With?

In centrioles, the hub is connected with the tubules of the peripheral triplets through the radial spokes composed of proteins.

It is called the hub and is proteinaceous in nature.

The centre portion of the proximal area of centrioles is proteinaceous in nature. It is referred to as the hub.

The cartwheel of centriole in centrosomes comprises 9 evenly spaced peripheral fibrils of the tubulin proteins.

Both the cylindrical centrioles lie perpendicular to each other wherein each of them has a cartwheel like organization.

The centrosome contains two cylindrical structures usually which are referred to as the centrioles.

Usually, centrosomes contain two cylindrical structures which are referred to as centrioles.

The cilium and flagellum emerge from the centriole-like structure referred to as the basal bodies.

There are nine radial spokes.

In the axoneme, a pair of centrally located microtubules are seen.

It comprises several microtubules which are parallel to the long axis.

The core of the flagella is called the axoneme.

In a cell, the cytoskeleton is involved in different functions such as motility, mechanical support, maintaining the cell’s shape etc.

Yes, microfilaments are a part of the cytoskeleton.

The 70S and 80S ribosomes both are composed of two subunits.

The 2 subunits of 70S ribosomes are 30S and 50S.

The 2 subunits of 80S ribosomes are 40S and 60S.

Ribosomes are granular structures. George Palade first observed ribosomes as dense particles.

In chloroplasts, the ribosomes are smaller (70S) compared to the cytoplasmic ribosomes (80S).

Thylakoid contains chlorophyll pigments.
