Joins Okazaki Fragments on the Adds Deoxyribonucleotides To

Unwinds DNA during replication Recognize splice sites and combine
with proteins to form spliceosomes

Joins Okazaki fragments on the Adds deoxyribonucleotides to

lagging strand the 3’ end of an existing chain

RNA molecules that function as Removes RNA primers and replaces

enzymes them with deoxyribonucleotides

Adds segments to the ends of Binds to the promoter and adds
chromosomes to prevent ribonucleotides during transcription
shortening during replication

Editing complex containing Charges up tRNA’s by adding the
“snurps” that removes introns correct amino acid
and splices together exons

Adds short RNA segments Short fragments made when the
to which DNA polymerase III can lagging strand is copied during
can attach nucleotides during replication
replication

Stabilize the unwound DNA Bind to operator sites of operons to

strand at the replication fork “turn off” genes

“death tag” that marks proteins Bind to mRNA’s and tag them for

for degradation by proteosomes digestion by ribonucleases

Type of RNA made by the nucleolus; Type of RNA containing the codon
combines with proteins to make region that is edited in eukaryotes

protein synthesis machinery before translation

Type of RNA containing the Region on DNA where RNA anticodon sequence that brings polymerase binds to start the correct amino acid into the transcription

ribosome

DNA segment upstream from Place in an operon where the
promoter that contains multiple repressor binds to “turn off” the
control elements to speed up gene
transcription

Amino acid polymer produced by Enzyme found in RNA viruses that

Ribosomes during translation catalyzes the production of DNA
