Transcription Flashcard

Front

What is the function of the mRNA poly-A tail?

Back

The mRNA poly-A tail protects the mRNA from degradation.

Front

What is the process by which genotype becomes expressed as phenotype?

Back

Gene expression.

Front

Which type of RNA contains codons that specify amino acids?

Back

mRNA (messenger RNA).

Front

What is transcription?

Back

Transcription is the process that creates an RNA product from a sequence of DNA.

Front

What role does RNA polymerase play in transcription?

Back

RNA polymerase builds RNA molecules from a DNA template.

Front

What is a promoter in the context of transcription?

Back

A promoter is a sequence of DNA within a gene where RNA polymerase can begin transcription.

Front

What is the false statement regarding RNA polymerase?

Back

RNA polymerase, like DNA polymerase, requires a primer to begin RNA synthesis.

Front

What occurs during the initiation step of DNA transcription?

Back

RNA polymerase attaches to the DNA at the promoter sequence of the gene.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) carries amino acids to the ribosome during translation.

Front

What is the difference between transcription and translation?

Back

Transcription is the synthesis of RNA from DNA, while translation is the synthesis of proteins from mRNA.
