DNA/RNA Transcription

Where does transcription occur

• mitochondria

• chloroplast

• nucleus

• cytoplasm

Which of the following structures carries the DNA information from the nucleus, out to a ribosome

• DAN

• mRNA

• tRNA

• rRNA

How many strands make-up an RNA molecule

• 1 strand

• 2 strands

• 3 strands

• 4 strands

The monomers that make up an RNA molecule consist which of the following

• phosphate, ribose, nitrogen base

• ribosomes, protein, fat

• acid, base, sugar

• deoxyribose, phosphate, nitrogen base

An original strand of DNA consist of: TAGCCTA. What would the stand of MRNA look like

• UAGCCUA

• ATCGGAT

• AUCGGAU

• TACGGTA

Which of the following correctly describes transcription

• DNA replicating its self

• MRNA is made from a DNA template

• An anticodon is formed

• proteins are made from amino acids

What compound (nitrogen base) will pair up with Adenine in a RNA molecule

• Thymine

• uracil

• guanine

• cytosine

Which of the following descriptions best describes which step of transcription the animation shows?

• elongation: RNA polymerase creating new nucleotides

• termination: stop gene, RNA polymerases detaching from DNA

• initiation: start gene, RNA polymerase attaching to DNA to start copying process

A strand of mRNA carries the code to specific amino acids that will construct specific proteins. what are these codes called?

• codons

• anticodons

• genes

• histones

The following if completed would be a good visualization of transcription ( copying of DNA) to translation( making proteins). What would be the DNA sequence for the particular amino acid

• CAT

• CAU

• GAT

• CTU
