[h] Transcription and Translation Click-On Challenge
[i] Notice the timer at the top right. Your goal is to build speed and accuracy. A good strategy: once through slowly, then additional trials to climb higher in the leaderboard.

600 x 470
Transcription
Yes! Step E is transcription.
HINT: Transcription takes DNA and makes it into RNA, which later gets translated into protein.
Removal of introns, other RNA processing
Way to go! Step F would involve removal of introns and other RNA processing.
HINT: RNA has to be processed before it gets translated. That happens in the nucleus. If product G1 represents ready-to-translate mRNA, then what must represent RNA processing?
the label for mRNA in the nucleus.
Very nice! G1 is mRNA in the nucleus
HINT: If step F is RNA processing, where would you find mRNA?
The label for mRNA in the cytoplasm.
Thumbs up. “G2” is mRNA is the cytoplasm.
HINT: mRNA is a single stranded nucleic acid that gets “read” by a ribosome during protein synthesis.
The label for an anticodon
Thumbs up! Group H is the label for an anticodon.
HINT: The anticodon is a group of three letters on a tRNA that bind with a 3 letter codon on the mRNA.
a single amino acid (attached to a tRNA).
Terrific. “M” is a single amino acid attached to an mRNA.
HINT: There are 20 amino acids, and they’re represented by initials like ‘met,” “pro,” “asp,” and “gly.”
A peptide bond.
Great! Letter “J” represents a peptide bond.
HINT: Peptide bonds connect amino acids.
A growing polypeptide.
Outstanding. “P” is a growing polypeptide.
HINT: A polypeptide is a chain of amino acids, connected together by peptide bonds
The label for a single tRNA (one that’s not carrying an amino acid)
Nice job! “O” is a single tRNA
HINT: A tRNA has a 3-letter anticodon on one side, and an amino acid binding site on the other side. Find one without an amino acid.
The label for a codon
Great work! “N” is the label for a codon.
HINT: A codon is a group of 3 letters in mRNA. Each codon codes for one amino acid.
The label for the ribosome.
Fantastic! ”K” is the ribosome.
HINT: The ribosome enables the tRNA anticodons to bind with the mRNA codons.
The label for the nuclear membrane.
Fantastic! “L” is the nuclear membrane.
HINT: The DNA is in the nucleus. Translation is happening in the cytoplasm. What’s the boundary between those two regions?
HINT: RNA is a single stranded molecule (in contrast to DNA, which is double stranded).
Nice! That’s the template strand.
HINT: The template strand is the DNA strand that RNA polymerase “reads” as it synthesizes a complementary strand of RNA
The template strand.
Awesome! “2” is the template strand of DNA.
HINT: The template strand is the DNA strand that RNA polymerase “reads” as it synthesizes a new strand of RNA.
Free RNA nucleotides
Correct. “3” represents free RNA nucleotides.
HINT: The free RNA nucleotides are the adenines (A), uracils (U), guanines (G), and cytosines (C) that are floating around in the cytoplasm, available for incorporation into a new strand of RNA.
The non-template strand.
Excellent! “4” is the non-template strand.
HINT: The non-template strand of DNA is the strand that isn’t being “read” by RNA polymerase.
The number for RNA polymerase
Good work! “5” is RNA polymerase.
HINT: RNA polymerase is the enzyme that “reads” the DNA and transcribes it into new RNA.

599 x 578
The letter for the cell’s selectively permeable outer boundary.
Yes! “A” is the cell membrane.
HINT: You’re looking for the cell membrane.
The letter for the site of most of the cell’s metabolic reactions
Way to go! It’s the cytoplasm (B).
HINT: You’re looking for the cytoplasm.
The letter for the substance that genes are made of.
Very nice! It’s DNA, at “C.”
HINT: You’re looking for DNA.
Transcription
Thumbs up! Transcription is represented by “e.”
HINT: Transcription is when DNA (a double helix) is converted into RNA, a single stranded molecule.
This letter could be any type of RNA (mRNA, tRNA, or rRNA) in the nucleus.
That’s right! Letter “f” could be any type of RNA.
HINT: Look in the nucleus for a single stranded molecule.
The letter for what controls what enters and leaves the nucleus.
Superb! Letter “d” is the nuclear membrane.
HINT: You’re looking for the nuclear membrane.
This molecule brings amino acids to the ribosome.
Terrific! It’s tRNA, at letter “i.”
HINT: You’re looking for a tRNA.
The letter for mRNA in the cytoplasm.
Outstanding: mRNA is at letter “h.”
HINT: mRNA is what gets “read” by a ribosome.
The letter for the part that converts information in mRNA into amino acid sequences.
Nice going! It’s the ribosome, at letter “j.”
HINT: You’re looking for a ribosome.
The letter for a newly synthesized polypeptide chain.
Incredible. Letter “g” represents a polypeptide chain.
HINT: Find the ribosome. A newly made polypeptide chain is hanging off of one of the tRNAs.
