Protein Synthesis Flashcard 3 (24-25)

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures that synthesize proteins by translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the function of the MC1R gene in hair and skin color?

Back

The MC1R gene produces a protein that is responsible for the production of melanin, which determines the color of hair and skin.

Front

How does ricin affect protein synthesis in cells?

Back

Ricin inhibits ribosomes, preventing cells from synthesizing proteins, which can be lethal.

Front

What is recombinant DNA technology?

Back

Recombinant DNA technology involves combining DNA from different organisms to produce new genetic combinations, often used in genetic engineering.

Front

What is the process by which a gene produces a protein?

Back

The process involves transcription (where DNA is converted to RNA) followed by translation (where RNA is used to synthesize proteins).

Front

What is the significance of alleles in determining traits like hair color?

Back

Alleles are different versions of a gene that can result in variations in traits, such as hair color, depending on whether they produce functional proteins.

Front

What is melanin and what role does it play in hair and skin color?

Back

Melanin is a pigment produced by the MC1R protein that gives hair and skin their color, with higher levels resulting in darker shades.

Front

What is the basic function of RNA in protein synthesis?

Back

RNA serves as a template for translating genetic information from DNA into proteins during the process of protein synthesis.

Front

What is chymosin and where is it produced?

Back

Chymosin is a protein produced in the stomach cells of young mammals, essential for digesting milk.

Front

How do genetically modified organisms (GMOs) relate to protein production?

Back

GMOs can be engineered to produce specific proteins, such as cheese proteins, by incorporating genes from other organisms.
