Front

Which of the following is NOT a step in mRNA Processing?

Back

C) DNA is replicated

Front

Which molecules are involved in translation?

Back

mRNA, transfer RNA (tRNA), ribosomes, and amino acids

Front

In the lac operon, what binds to the promoter to start transcription?

Back

RNA Polymerase

Front

In the lac operon, what must be present to remove the repressor so the genes for lactose can be transcribed?

Back

Lactose

Front

What is mRNA?

Back

Messenger RNA, a type of RNA that carries genetic information from DNA to the ribosome for protein synthesis.

Front

What are introns?

Back

Non-coding segments of RNA that are removed during mRNA processing.

Front

What are exons?

Back

Coding segments of RNA that are joined together during mRNA processing.

Front

What is the role of ribosomes in translation?

Back

Ribosomes facilitate the binding of tRNA to mRNA and catalyze the formation of peptide bonds between amino acids.

Front

What is a repressor protein?

Back

A protein that binds to an operator in DNA and inhibits transcription of the genes.
