Organize these options into the right categories.

Groups:

(a) DNA

,

(b) RNA

,

(c) BOTH

• involved in transcription

• double stranded

• single stranded

• involved in replication

• carries the genetic code

• nucleic acid

• A-T, C-G

• A-U, C-G

• cannot leave the nucleus

• can leave the nucleus

• involved in translation

Look closely at the picture.

Select all answers that correctly describe what is happening.

• DNA is copying itself

• RNA is being made

• DNA is a template strand

• This process is transcription

• This is inside the nucleus

Look closely at the picture.

Select all answers that correctly describe what is happening.

• mRNA brings amino acids to the ribosome

• amino acids are bonded together to form a chain

• this process is translation

• ribosomes are where polypeptide chains are built

• DNA is directly involved

Use the codon wheel to match each codon to its amino acid.

Reorder the steps of protein synthesis from first (left) to last (right).

• tRNA leaves an amino acid

• mRNA leaves the nucleus

• amino acids bond together to form a chain

• mRNA codons match with tRNA anticodons in the ribosome

• DNA is used to make mRNA

Why is mRNA created?

• it helps DNA get out of the nucleus

• it transfers amino acids to the ribosome

• it delivers the genetic code to the ribosome

• it copies DNA during replication

Match each of the complementary sequences to the correct process.

• translation

  (mRNA codon matches to tRNA)

• A T T C

  T A A G

• transcription

  (DNA → mRNA)

• U U C A

  A A G U

• replication

  (DNA → DNA)

• T A T G

  A U A C
