Ribosomes and Cilia

• Ribosomes look like tiny dots inside the cytoplasm
• Generally, all cells contain the Ribosome.
• Ribosomes are tasked with the synthesis of protein chains.
• They do this by creating long protein chains that are then sent into the
cytoplasm and absorbed by organelles, etc.
• “In the process of the synthesis of protein chains the messenger RNS codons
are read by the anticodons of adaptor, transfer RNAs (tRNAs) that carry
codon-specific amino acids. These amino acids are added to a growing
protein chain by a peptide bond formation in the center of the Ribosome.”
• “A codon is a nucleotide that specifies an amino acid.”
• “The ribonucleic acid (RNA) that is directly involved in the
transcription of the pattern of bases from the DNA to provide a
blueprint for the construction of proteins is called messenger
RNA or typically mRNA
• In a factory the ribsome would play the role of assembly line.
• Cilia is a small, microscopic, hair-like moving structure. They
occur in large quantities on the surface of certain cells.
Cilia are not independent,
they are attached to the
cell’s outer layer, as shown
in the picture to the left. The
tentacle- looking objects
are cilia.
• It helps move fluids across the surface in an animal cell
• If a cilia were working in a factory it would work in the shipping
Section of the factory, or moving things from one area to another.
