What is the role of RNA polymerase during transcription?

It binds to a promoter region on DNA

It translates mRNA into amino acids

Which strands are formed when RNA polymerase unwinds DNA?

Template and nontemplate strands

The bonding rules for constructing mRNA from DNA are

What happens to introns during mRNA processing?

They are translated into proteins

They are spliced together with exons

What modifications are made to mRNA before it leaves the nucleus?

A 5' cap and a poly-A tail are added

A 3' cap and a poly-G tail are added

A 5' cap and a poly-G tail are added

A 3' cap and a poly-A tail are added

What is protein synthesis described as in cells?

What is the role of the A site in the E. coli ribosome during protein synthesis?

Binds incoming charged tRNAs with specific amino acids

Holds tRNAs with amino acids bonded to polypeptide chain

Releases dissociated tRNAs for recharging

Signals termination of translation

What happens to mRNA after translation is complete?

It is degraded for nucleotide reuse

It is reused for another round of translation

Which statement about the genetic code is correct?

It is universal across most species

What is the role of mRNA in translation?

It attaches to the ribosome and is read 3 nucleotides at a time.

It forms peptide bonds between amino acids.

It carries amino acids to the ribosome.

It repeats the cycle until the polypeptide is complete.

Match the following tRNA functions with their descriptions in protein synthesis.

It forms a peptide bond with the previous amino acid.

It arrives at the ribosome using an anticodon to match the corresponding codon.

It reads the mRNA three nucleotides at a time.

It completes the polypeptide and leaves the ribosome.
