What did Venkatraman Ramakrishnan discover?

What did Venkatraman Ramakrishnan discover?

Using a method known as x-ray crystallography, Venkatraman Ramakrishnan and other researchers were able to collaborate to map the structure of ribosomes, made up of hundreds of thousands of atoms, in 2000. Among other applications, this has been important in the production of antibiotics.

Which model is used to study the structure of ribosome?

All three have used a method called X-ray crystallography to map the position for each and every one of the hundreds of thousands of atoms that make up the ribosome. Inside every cell in all organisms, there are DNA molecules.

Who discovered structure of ribosome?

In 1955, George E. Palade discovered ribosomes and described them as small particles in the cytoplasm that preferentially associated with the endoplasmic reticulum membrane.

Who received a Nobel Prize on the structure and function of ribosomes *?

In 2009, Thomas Steitz, the Sterling Professor of Molecular Biophysics & Biochemistry, was awarded the Nobel Prize in Chemistry for “studies of the structure and function of the ribosome,” along with Venkatraman Ramakrishnan of the MRC Laboratory of Molecular Biology and Ada E.

What is the contribution of Venkatraman Ramakrishnan?

Venkatraman ‘Venki’ Ramakrishnan is a Nobel Prize-winning biologist whose many scientific contributions include his work on the atomic structure of the ribosome.

How are ribosomes structured?

Ribosomes are made of proteins and ribonucleic acid (abbreviated as RNA), in almost equal amounts. It comprises of two sections, known as subunits. The tinier subunit is the place the mRNA binds and it decodes, whereas the bigger subunit is the place the amino acids are included.

How does the structure of ribosomes relate to its function?

The grooves of the ribosome allow for mRNA to be held in place while tRNA reads the “code” that determines which amino acid is next in the sequence. It is the very structure of ribosomes that completes the Central Dogma of Biology, or DNA to RNA to Protein.

What is the structure of ribosomes?

A ribosome is made out of RNA and proteins, and each ribosome consists of two separate RNA-protein complexes, known as the small and large subunits. The large subunit sits on top of the small subunit, with an RNA template sandwiched between the two.

Who discovered ribosomes as dense particles under the electron microscope?

George Palade
Ribosomes are granular structures, first observed under electron microscope as dense particles by George Palade (1953).

Who was awarded the Nobel Prize in Physics in 1930?

Sir Chandrasekhara Venkata Raman
The Nobel Prize in Physics 1930 was awarded to Sir Chandrasekhara Venkata Raman “for his work on the scattering of light and for the discovery of the effect named after him.”
