Transcription (H)

The first step of protein synthesis is.....

• replication

• mitosis

• translation

• transcription

The molecule that synthesizes the mRNA inside the nucleus

• DNA polymerase

• Nucleotides

• RNA polymerase

• helicase

What is a Codon?

• 4 base pairs that transfer to amino acids
• 3 base pairs that transfer to amino acids
• 3 base pairs that transfer to DNA
• 3 base pairs that transfer to mRNA

Where does transcription take place?

• nucleus
• cytoplasm
• ribosome

RNA polymerase moves in which direction along the DNA?

• 5' to 3' 
• 3' to 5' along the template strand
• 3' to 5' along nontemplate(coding) strand
• 5' to 3' along the template strand

Which RNA bases would pair with TACGAA in transcription? 

• AUGCUU
• ATGCTT
• GCATCC
• GCAUCC

The parts of a gene that do NOT code for amino acids in a protein are called

• introns
• exons
• codons
• anticodons

In eukaryotic cells, transcription cannot begin until 

• the two DNA strands have completely separated and exposed the promoter.
• several transcription factors have bound to the promoter.
• the 5' caps are removed from the mRNA.
• the DNA introns are removed from the template.

The production of mature mRNA in eukaryotes involves

• cutting introns out and spicing exons together
• adding the 5' cap
• adding the 3' poly A tail
• all of these are correct

All of the following are true EXCEPT:

• Gene expression involves transcription and translation

• Transcription copies DNA to RNA

• Translation copies RNA to protein

• All RNAs are translated into protein
