How would you describe a ribosome?

How would you describe a ribosome?

The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells. In 1955, George E. Palade discovered ribosomes and described them as small particles in the cytoplasm that preferentially associated with the endoplasmic reticulum membrane.

Do ribosomes look like dots?

Ribosomes are the cellular structures responsible for protein synthesis. When viewed through an electron microscope, ribosomes appear either as clusters (polyribosomes) or single, tiny dots that float freely in the cytoplasm.

What does a ribosome look like analogy?

An analogy for ribosomes is a factory. Ribosomes are like a factory because they produce protein for the cell. Ribosomes make protein for all cells. …

What is the Colour of ribosomes?

Ribosomes can be found all throughout the cytoplasm, but many are located on the endoplasmic reticulum. Find all the ribosomes and color red.

What are ribosomes in one word?

ribosome. / (ˈraɪbəˌsəʊm) / noun. any of numerous minute particles in the cytoplasm of cells, either free or attached to the endoplasmic reticulum, that contain RNA and protein and are the site of protein synthesis.

Do ribosomes build DNA?

In eukaryotes, ribosomes get their orders for protein synthesis from the nucleus, where portions of DNA (genes) are transcribed to make messenger RNAs (mRNAs). An mRNA travels to the ribosome, which uses the information it contains to build a protein with a specific amino acid sequence.

What do Golgi bodies look like?

The Golgi apparatus (GA), also called Golgi body or Golgi complex and found universally in both plant and animal cells, is typically comprised of a series of five to eight cup-shaped, membrane-covered sacs called cisternae that look something like a stack of deflated balloons.

What is similar to a ribosomes?

Endoplasmic Reticulum The ribosomes in a cell are like the kitchen in a house. It is similar to ribosomes using amino acids to make proteins. The endoplasmic reticulum, or ER, transports things across the cell, and helps make proteins and lipids. The mitochondrion are like the electricity in a house.

What Colour is mitochondria?

Mitochondria, from liver, concentrated in a pellet are opaque and distinctly yellow in color but when dehydrated and cleared become a transparent red. Submicroscopic particles form a translucent cherry red pellet which when dehydrated and cleared shows a transparent red color deeper than that of the mitochondria.

What color is a nucleolus?

It also contains DNA assembled into chromosomes. The nucleus is surrounded by the nuclear membrane. Color and label the nucleolus dark blue, the nuclear membrane yellow, and the nucleus light blue. Materials can move from the nucleus to the cytoplasm through nuclear pores in the membrane around the nucleus.
