What part of the cell is like a construction site?
A construction site can be compared to a part of a cell called ribosomes. Ribosomes make protein and protein helps make new cells and repair old ones.
What would ribosomes be in a cell?
Ribosomes are found ‘free’ in the cytoplasm or bound to the endoplasmic reticulum (ER) to form rough ER. In a mammalian cell there can be as many as 10 million ribosomes. Several ribosomes can be attached to the same mRNA strand, this structure is called a polysome. Ribosomes have only a temporary existence.
Where are ribosomes in the cell?
Ribosomes are mainly found bound to the endoplasmic reticulum and the nuclear envelope, as well as freely scattered throughout the cytoplasm, depending upon whether the cell is plant, animal, or bacteria.
Where are ribosomes found in a cell write their functions?
Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum. Their main function is to convert genetic code into an amino acid sequence and to build protein polymers from amino acid monomers.
How are ribosomes and construction sites alike and different?
1. Construction Site + Ribosomes A construction site is like ribosomes because they both build and create things. A construction site in charge of buildings and the ribosomes are in charge of creating proteins, it represents both animal and plant cells
Where are ribosomes found in a living cell?
Ribosomes are important cell organelles. It does RNA translation, building proteins from amino acids using messenger RNA as a template. Ribosomes are found in all living cells, prokaryotes as well as eukaryotes. A ribosome is a mixture of protein and RNA that starts being made in the nucleolus of a cell.
What are the functions of ribosomes in prokaryotes?
Prokaryotes have 70S ribosomes while eukaryotes have 80S ribosomes. Around 62% of ribosomes are comprised of RNA, while the rest is proteins. The structure of free and bound ribosomes is similar and is associated with protein synthesis. The important ribosome function includes:
How is the ribosome a micro-machine for making proteins?
Quick look: A ribosome is a cell organelle. It functions as a micro-machine for making proteins. Ribosomes are composed of special proteins and nucleic acids. The TRANSLATION of information and the Linking of AMINO ACIDS are at the heart of the protein production process.A ribosome, formed from two subunits locking together,…
