TRNA brings amino acids to the nucleus or ribosomes?
The ribosome 'reads' the mRNA message , and tRNA takes amino acids to the ribosome, in the sequence that is determined by the mRNA. This all takes place in the cytoplasm [in the Rough Endoplasmic Reticulum - RER], not the nucleus.
What is the rough ERs job in the animal cell?
The rough ER is the part of the endoplasmic reticulum that has the ribosomes on it.The ribosomes begin synthesizing a protein and stick to the ER so all it does is hold the ribosomes.Source: http://en.wikipedia.org/wiki/Endoplasmic_reticulum#Rough_endoplasmic_reticulum
Which structure makes proteins using coded instuctions that come from the nucleus?
Some ribosomes can be found floating free in the cytoplasm, while others are bound to the rough endoplasmic reticulum. (The name "rough" actually indicates the presence of ribosomes, against the "smooth" appearance of the smooth endoplasmic reticulum, which lacks ribosomes). There are several types of ribosomes,(rRNA = ribosomal RNA, mRNA = messenger RNA, tRNA = transfer RNA), all of which has its distinct job in the synthesizing process of protein. Information of regarding this process can be found on http://en.wikipedia.org/wiki/Protein_synthesis Ribosomes are considered "non-membranous organelles", as they differ from other organelles which are membrane-bound.The ribosomes.
Why is the tibia involved in the transfer of weight to the ankle and foot but not the fibula?
As the tibia approaches the ankle joint, the tibia broadens, and the medial border ends in the medial malleolus. The inferior surface of the tibia articulates with the proximal bone of the ankle; the medial malleolus provides medial support for this joint. whereas the lateral malleolus of the fibula only provides lateral stability to the ankle but does not help transfer weight to the ankle and foot.
What does a plant cell and a animals cell have in common?
the plant and animal both have a nucleus, that is what they have in common
What does the endoplasmic reticulum do in a plant cells?
the endoplasmic reticulum moves things around in the cellEndoplasmic reticulum are large netwok of membrane bound tubes. Its functions are-Serves as a channel for the transport of materials.Performs certain biochemical activity.Plays a role in detoxifing poisons and drugs.It is a site of protein manufacture.
What are the functions and types of endoplasmic reticulum?
The rough endoplasmic reticulum is covered in ribosomes and helps produce most of the proteins. Smooth endoplasmic reticulum does not have these ribosomes, and is almost solely for producing lipids.
What is the rough endoplasmis reticulum?
The rough endoplasmic reticulum is a network of membranesin the cytoplasm of eukaryotic cells.The membranes enclose a continuous cavity, the lumen, that is separated from the cytoplasm. The lumen of the rough endoplasmic reticulum is continuous with that of the smooth endoplasmic reticulum and with the nuclear envelope.The term "rough" applies to the appearance of the membranes under the electron microscope. They have small, more or less spherical spots attached to them; these are ribosomes. The ribosomes are the sites of polypeptide synthesis. All polypeptides are initially synthesized at free ribosomes in the cytosol, but certain amino acid sequences stimulate special molecules to transfer the ribosomes to the rough endoplasmic reticulum, where polypeptide synthesis continues, with the ribosome embedded in the membrane of the endoplasmic reticulum, and the polypeptide formed in the lumen of the endoplasmic reticulum.Polypeptides synthesized in the rough endoplasmic reticulum form proteins that are destined for secretion or for certain locations within the cell, including the plasma membrane, lysosomes, or the endoplasmic reticulum itself.The rough endoplasmic reticulum also transports materialsthrough the cell. The lumen forms a series of channels through which these materials can move from one place in the cell to another without entering the cytoplasm.
What has ribosomes attached to it and it synthesizes proteins?
In translation, messenger RNA and transfer RNA and ribosomes work together to produce proteins. Ribosomes are very tiny particles that are present in large numbers in all living cells and serve as the site of protein synthesis.
What makes up cells?
Cells are full of many organelles that have different functions. Plant cells have cell walls with a cytoplasm, central vacuole, ribosomes, endoplasmic reticulum, chloroplasts, dna, messenger rna, transfer rna, and smaller vacuoles. Animal cells have a cell membrane, nucleus, nucleolus, ribosomes, endoplasmic reticulum, mitochondria, dna, messenger rna, transfer rna. Unicellular organisms usually have or do not have a cell membrane with various organelles listed above depending on the organism. Hope this helps! -DrkMnlight
Does the Golgi apparatus make proteins?
No. The Golgi apparatus of a eukaryotic cell primarily modifies proteins delivered from the rough endoplasmic reticulum. It is also involved in the transfer of lipids inside the cell and the formation of lysosomes. A cell's ribosomes are responsible for protein production.
What is the function of rough endoplasmic?
In this question it seemed like you were referring to the organelles on the rough endoplasmic reticulum which, by the way, are called ribosomes. Ribosomes binds to mRNA (messenger RNA) and assembles protein using tRNA (transfer RNA) complex. They are also the sites responsible for protein synthesis. It's been described as a kind of platform where proteins are built. They use the RNA copy of a gene to read it like a 'copy of a blueprint' to construct the protein needed. If that is not what you were looking for then this is the function of the rough endoplasmic reticulum: The rough endoplasmic reticulum is a membranous structure that associates closely with the nucleus. Embedded in the membrane of the structure are ribosomes, this is what gives the "rough" appearance. RNA passes through the ribosomes where its sequence of nucleic acid codes for specific amino acids to be joined up in a specific order. The route through the ribosomes for the amino acid takes them into the membranes of the reticulum where they can be kept together. They are then moved of in vesicles formed from the ER membranes to the Golgi Apparatus to be packaged and processed.
How heat transfer is controlled?
There is a special mechanism that controls heat transfer.
What does the acronym RER stand for?
The acronym RER could stand for a number of different interpretations. One could refer to the rapid transfer system used in France, or it could be rough endoplasmic reticulum in biology. There are even more meanings, so it is usually best not to use acronyms.
Which mechanism is not a way to transfer heat?
Fusible link
What is the heat transfer mechanism responsible for the daily wind cycle?
heat transfer through convection.
What is a risk transfer mechanism?
a third party guarantee or an insurance
