A specialized structure within a cell that has its own specific function is known as a/an _______.
vichka [17]

Answer:

Organnelle

Ribosomes

Nucleus

Archaeabacteria

Phospholipid bilayer

Lipases

Explanation:

1. Organnelles are specialized structures in a cell designed to perform a particular function that will make the cell normal e.g. ribosome, Chloroplast, mitochondrion are examples of organnelles.

2. The Rough Endoplasmic Reticulum (RER) is one of the two endomembranous systems in the cell. It is characterized by its rough appearance which occurs as a result of ribosomes attached to its surface. This attachment of ribosomes makes its function related to protein synthesis.

3. Nucleus is a membrane bound organnelle found only in EUKARYOTIC cells. It houses the genetic material (DNA) of a cell and acts as the brain by directing all of the cellular activity of that cell.

4. Archaeabacteria is one of the six kingdoms in the hierarchical classification of living organisms. They contain unicellular and prokaryotic organisms that are uniquely characterized by their ability to survive extreme conditions e.g high temperature.

5. The plasma membrane is an outer covering that bounds the cells of both Prokaryotic and eukaryotic organisms. According to the fluid mosaic model that describes the structure of the cell membrane, it contains a phospholipid layer that confines its selective permeability upon it i.e. ability to control what goes in and out of the cell. This is due to the amphipathic nature of the phospholipid i.e. contains an hydrophobic and hydrophilic region.

6. Lipases are enzymes that are involved specifically in the breakdown of lipids and fat molecules into fatty acids and glycerol.

Use the following table to answer the question:
postnew [5]

Translating the code by the table informed, the message found in rna will be CAT-GTA-TGG.

<h3>What is the genetic code of DNA is RNA?</h3>

The genetic code is made up of four bases: adenine (A), cytosine (C), guanine (G) and uracil (U). The combination of these bases determines the amino acid necessary for the formation of a protein.

Translation is a process in which the message contained in the mRNA molecule will be read by the ribosome, decoding the nucleic acid language into the protein language. In this case, we have:

GTA-CAT-ACC
