Front

The monomers of all nucleic acids

Back

nucleotides

Front

Three parts of all nucleotides

Back

a 5C sugar, phosphate group and a nitrogen base

Front

Enzyme that "unzips" the DNA double helix during DNA replication

Back

helicase

Front

Enzyme that is responsible for building two new complementary strands to match the two original ones during DNA replication

Back

DNA polymerase

Front

What bases match up in complementary base pairing in DNA?

Back

A goes with T

C goes with G

Front

What bases match up in complementary base pairing when you go from DNA to RNA?

Back

A goes with U

T goes with A

C goes with G

Front

Nucleic acid that is single-stranded, fragile, has ribose sugar, contains uracil, can travel throughout the cell and is used to make proteins

Back

RNA

Front

Nucleic acid that is double-stranded, stable, has deoxyribose sugar, contains thymine, must stay in the nucleus and carries the genetic code

Back

DNA

Front

RNA that carries a copy of the genetic information found in DNA to the ribosomes

Back

mRNA

Front

RNA that "reads" the message from DNA, in order to interpret which amino acids are needed

Back

rRNA
