Unit 4 Exam: Gene Expression

Front

What is the correct amino acid sequence for the mRNA code AUG GCA AAC CGU?

Back

Met-Ala-Asn-Arg

Front

Which form of RNA carries amino acids from the cytoplasm to the ribosome?

Back

Transfer RNA (tRNA)

Front

What is the direction of genetic information flow?

Back

DNA -> RNA -> Protein

Front

What is shown in the diagram that represents the structure of DNA?

Back

DNA

Front

What nitrogenous base does DNA have that RNA does not?

Back

Thymine

Front

What are the three main types of RNA involved in gene expression?

Back

mRNA, tRNA, rRNA

Front

What is the role of messenger RNA (mRNA) in protein synthesis?

Back

mRNA carries the genetic code from DNA to the ribosome for protein synthesis.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid.

Front

What is the function of ribosomal RNA (rRNA)?

Back

rRNA forms the core of the ribosome's structure and catalyzes protein synthesis.

Front

What is transcription in the context of gene expression?

Back

Transcription is the process of copying a segment of DNA into RNA.
