Unit 5 Dna Flashcards

Front 1

double helix

Back 1

shape of the DNA molecule; two DNA stands are twisted into a springlike structure; twisted ladder

Front 2

nitrogenous base

Back 2

carbon ring structure found in DNA or RNA that contains one or more atoms of nitrogen; includes adenine , guanine ,cytosine ,thymine,and uracil

Front 3

transcription

Back 3

in plants the loss of water through

Front 4

translation

Back 4

process of converting information in mRNA into a sequence of amino acids in a protein

Front 5

codon

Back 5

set of three nitrogenous bases that represents an amino acid;order of nitrogenous bases in mRNA determines the type and order of amino acids in a protein

Front 6

mutation

Back 6

any change or random error in a DNA sequence

Front 7

mutagen

Back 7

any agent that can cause a change in DNA includes high-energy radiation,chemicals or high temperatures

Front 8

messenger RNA

Back 8

RNA that transports information from DNA in the nucleus to the cell's cytoplasm

Front 9

ribosomal RNA

Back 9

nonmembrane- bound organelles in the nuclues where proteins are assembled

Front 10

transfer RNA

Back 10

RNA that transports amin acids to the ribosomes to be assembled into proteins
