INTRODUCTION

The structure of a ribosome complex involved in a protein

process

By a wonderful technique they vizualized mRNA and

associated molecules

How Cells Export And Embed Proteins In The

Membrane The

ribosomes found on  the RE fabric  proteins that are export outside cell

 The proteins move  from the ER and accumulated near the Golgi apparatus and

How Cells Export And Embed Proteins In The Membrane

The Proteins are "eliminated" from membrane in vesicles by channels

How Cells Export And Embed Proteins In The Membrane

• Transduction of external signals produces a response from the target cell

• This response is impaired as a result of activation or inhibition of a metabolic pathway

How Cells Export And Embed Proteins In The Membrane

•  An international team of researchers to find another mystery related to the ribosomes - the enigmatic jumbles of molecules

• the journal Nature, could help in developing new antibiotics to combat multi-resistant superbugs such as MRSA(methicillin-resistant Staphylococcus aureus infection) found inmany U.S. hospitals

ANOTHER STUIDES…

OBSERVATION

This investigacions raises that the

complex ribosome-

protein and the receptor act as a

«switch», so it can stop

They raises to that it more

studies productions of proteins

can be controled

It could indicated

to the stop of many

deseases

In Scientific First, Researchers Visualize Naturally Occurring mRNA

• Messenger RNA, the key intermediary in gene expression, translating the DNA's genetic code into the amino acids that make up proteins

In Scientific First, Researchers Visualize

Naturally Occurring mRNA

• There are 20 amino-acids forming  sub-units for proteins while only four nucleic bases are used to construct the RNA or DNA

In Scientific First, Researchers Visualize Naturally Occurring mRNA

• The mature mRNA is transported to the cytoplasm of the cell, in the case of eukaryotes beings through nuclear membrane poresMessenger RNA in the cytoplasm is coupled to the ribosomes

In Scientific First, Researchers Visualize Naturally Occurring mRNA

• mRNA are the machinery responsible for protein synthesis.After a certain amount of time the mRNA is degraded into its component nucleotides, usually with the assistance of ribonucleases

OBSERVATION

It is an important

study because they are in the way to control

gene expressions

This control can cure

many desease with

genetic origin

It is a useful

technique to

monitored mRNA

MEDICAL UTILITY

MEDICAL UTILITY

Both studies can be very benefical for discover deseases and try to find a cure for it, because molecular biology is basis of all functions of our bodies
