Question

describe the production and processing of a protein that will be exported from a eukaryotic cell. Start with the separation of the mRNA from the DNA template in and with the release of the protein at the plasma membrane.

Answer 1

Protein is a large molecule made from chains of amino acids, which are the subunits of protein molecules. Eukaryotes produce these proteins through a process called protein synthesis. ... Transcription is the process of creating mRNA from DNA, and translation is when ribosomes read the mRNA and synthesize a protein.

Proteins are one of the most abundant organic molecules in living systems and have an incredibly diverse range of functions. Proteins are used to:

• Build structures within the cell (such as the cytoskeleton)
• Regulate the production of other proteins by controlling protein synthesis
• Slide along the cytoskeleton to cause muscle contraction
• Transport molecules across the cell membrane
• Speed up chemical reactions (enzymes)
• Act as toxins

Each cell in a living system may contain thousands of different proteins, each with a unique function. Their structures, like their functions, vary greatly. They are all, however, polymers of amino acids, arranged in a linear sequence
