Match each type of RNA with its description. -pre-mRNA

For each item or event, indicate the process it is associated with. -ER membrane

What does the degeneracy of the genetic code refer to?

Which molecule is involved in transcription?

Transcription Diagram -In the transcription diagram, what is the name of item E?

In which complex does the process of removing introns from mRNA and putting the remaining exons together occur?

The studies of alkaptonuria provided the first evidence of a connection between genes and metabolism. Who conducted these studies?

At the start of translation, where is the initiator tRNA base paired with the start codon?

For each item or event, indicate the process it is associated with. -signal peptidase

Which type of transcription are the proteins called transcription factors involved in?

Proteins are assembled from the instructions found in which molecule?

Which codon/amino acid pairing represents the universal start codon in eukaryotes?

Where does the process of translation of nuclear protein-coding genes in eukaryotic cells occur?

What triggers the termination of transcription in prokaryotes?

Genetic Code Table -Suppose that an mRNA molecule is made complementary to the DNA sequence 3'-CTTACATGGCATCC-5'. In the genetic code table, the incorporation of which amino acid in the polypeptide is directed by the third codon (counting the start codon as the first codon)?
