The Genetic Code
100

This nucleotide replaces thymine in RNA

uracil

100

The process of making RNA from DNA


transcription

100

Translation occurs in this organelle

ribosome

100

codons are composed of how many nucleotides?

three

200

This sugar is found in RNA nucleotides

ribose

200

The enzyme responsible for building RNA during transcription

RNA polymerase

200

A three-nucleotide sequence on mRNA that specifies an amino acid

codon

200

The codon AUG serves as this important signal

start codon

300

The type of RNA that carries DNA's instructions to the ribosomes

mRNA


300

Eukaryotic RNA must undergo this type of processing before leaving the nucleus

RNA processing (post-transcriptional modification)

300

The first amino acid typically added during translation in eukaryotes 

methionine

300

What is the term for when base pairing doesn't strictly follow the usual rules when coding for amino acids?

Wobble

400

RNA polymerase binds to this region to begin transcription

promoter

400

During RNA splicing, these non-coding segments are removed

introns

400

The portion of tRNA that binds to mRNA codons

anticodon

400

More than one codon can code for the same amino acid, making the genetic code

redundant

500

The strand of DNA used by RNA polymerase to create complementary RNA

template strand

500

This RNA sequence allows proteins to bind and stabilize the RNA during processing

poly-A tail

500

The direction in which ribosomes read mRNA

5' to 3'

500

Scientists use the fact that the genetic code doesn't vary among organisms to study
