Protein Synthesis Flashcard 2 (24-25)

Front

What is the role of RNA in protein synthesis?

Back

RNA molecules are responsible for making proteins by transcribing the genetic information from DNA and translating it into amino acid sequences.

Front

What cellular structure is responsible for building proteins?

Back

Ribosomes are the cellular structures that synthesize proteins by linking amino acids together in the order specified by mRNA.

Front

How does DNA influence the phenotype of an organism?

Back

DNA contains the genetic instructions that are transcribed into RNA, which then translates into proteins that determine the organism's traits, such as hair color.

Front

What is the process of transcription in protein synthesis?

Back

Transcription is the process by which the information in a DNA sequence is copied into a complementary RNA sequence.

Front

What is the mRNA sequence transcribed from the DNA sequence TAC GCA TAA AAA ACT?

Back

The mRNA sequence transcribed from the DNA sequence TAC GCA TAA AAA ACT is AUG CGU AUU UUU UGA.

Front

What is the function of ribosomes in the cell?

Back

Ribosomes function as the site of protein synthesis, where they translate mRNA into polypeptide chains.

Front

What is the significance of the T1R2 protein in taste perception?

Back

The T1R2 protein is a receptor that taste buds use to detect sweet flavors.

Front

What is the relationship between DNA, RNA, and proteins?

Back

DNA is transcribed into RNA, which is then translated into proteins; this flow of information is known as the central dogma of molecular biology.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.
