Protein Synthesis Flashcard 2 (24-25) (PORTUGUESE)

Front

What is the role of RNA in protein synthesis?

Back

RNA serves as a template for the synthesis of proteins by carrying the genetic information from DNA to the ribosomes, where proteins are assembled.

Front

What is the function of ribosomes in a cell?

Back

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

Front

What is the process of transcription in protein synthesis?

Back

Transcription is the process by which the information in a segment of DNA is copied into messenger RNA (mRNA).

Front

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

Back

The T1R2 protein is involved in the detection of sweet flavors by taste receptor cells.

Front

How does DNA influence phenotypic traits such as hair color?

Back

DNA contains the instructions for producing RNA, which in turn produces proteins that determine phenotypic traits like hair color.

Front

What is the sequence of mRNA 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 relationship between DNA, RNA, and proteins?

Back

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

Front

What are the three main types of RNA involved in protein synthesis?

Back

The three main types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

Front

What is the role of transfer RNA (tRNA) in protein synthesis?

Back

tRNA transports specific amino acids to the ribosome during protein synthesis, matching them to the corresponding codons on the mRNA.

Front

What is a codon and its significance in protein synthesis?

Back

A codon is a sequence of three nucleotides on mRNA that corresponds to a specific amino acid or a stop signal during protein synthesis.
