What is the step after a messenger RNA binds to their ribosomes small sub units?

From a Gene in Chromosomes, a single stranded copy of messenger RNA goes to Ribosomes, the protein manufacturing sub units and get attached to it. There is sequence of codons in messenger RNA, giving order to ribosomes to put the denoted amine acid one by one as per the sequence of codons.(There is specific codons for each of the 20 amine acids.) There are multiple sites, at witch specific amine acids are attached at a time.These amine acids are brought at the site by Transfer RNA. So we have a specific protein with a given sequence as per gene is produced.If a single amine acid is short, then the entire chain is broken down and amine acids are used as a source of energy, giving rise to 4 kilocalary/ gram.(Same as Glucose.)

Why ribosomes are of 70s in mitochondria of eukaryotic cell?
Prokaryotes have 70S ribosomes, each consisting of a small (30S) and a large (50S) subunit.
Where the assembly of ribosomes begins?
They are made in the nucleolus. Parts are brought and assembled in cytoplasm
Where are ribosomes formed in cells?
Ribosome in a eukaryote is formed in the cytoplasm and definitely not in the nucleolus of the nucleus . There seems to be a confusion between ribosomes and ribosomal sub units . Ribosomal sub units are indeed formed in the ncleolus . yes , agreed . But when some body raises a questions 'Where exactly ribosomes are formed ' ? The answer is - cytoplasm and definitely not nucleolus . What do my friends who read this say !!!
What size are the motor units in the eye?
The motor units of the eye are small. Small motor units are found where precise movements are needed as in the muscles of the eye.
What organelles participate in protein synthesis?
There are three organelles involved in protein synthesis. Golgi Apparatus, flattened membrane sacs and vesicles chemically modify protein. Rough Endoplastic Reticulum, contains a network of membranous sacs that bring synthesized proteins to the service. Ribosomes, which have two units, small and large, initializes and completes the protein synthesis.
What are the small units that make up a rna molecule called?
Ribosomes
What units are ribosomes measured in?
Svedberg units.
What is the small part of the nucleus where ribosomal subunit formation takes place?
The small unit found in ribosomes are called subunits. They are denoted according to their sedimentation coefficients in the Svedberg units. The 40S is the subunit for eukaryotic ribosomes, while the 30S is the subunit for prokaryotic ribosomes.

In ribosomes measurement what is the unit 'S'?
Svedberg Units
What are the basic units from which proteins are built up?
ribosomes
What are facts about ribosomes?
Here are some facts: Ribosomes are small organelles found in the cells of all life forms. They are quite small, only AAA few hundred nanometres across. It has been theorized that ribosomes were once independent life forms, reproducing on their own, until other chemicals such as carbohydrates and DNA were brought into the fold at AAA later time. Ribosomes are composed of rRNA and other proteins. Their main function is to produce a variety of proteins from simple genetic instructions which propagate outwards from the cellular nucleolus in the form of messenger RNA. Ribosomes float in the cytoplasm of a cell or bind to the endoplasmic reticulum, ribbon like structures found inside of the cell. quick facts(written by myself) ¢Ribosome's are the workbenches where proteins get manufactured¢Ribosome composes 25% of cell mass¢ They get their name from their size.¢A bacterial cell contains a few thousands of ribosome's, although a human cell has a few million¢Ribosome's are made up of two subunits, the large and small subunit.¢When the two units are docked together with a special information unit called messenger RNA, they make proteins

How many units do ribosomes function as?
Two part units. There are two compartments.A larger one and a smaller one
The basic unit of messenger RNA?
Amino acids are the basic units of messenger RNA. mRNA is synthesized from DNA and is a single stranded molecule.
