Unit 5 Dna Flashcards

Front 1

Double Helix

Back 1

shape of DN molecule formed when two twisted DNA strands are coiled into a springlike structure and held together by hydrogen bonds between the bases

Front 2

Nitroenous Base

Back 2

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

Front 3

Transcription

Back 3

process in the cell nucleus where enzymes make an RNA copy of a DNA strand

Front 4

Translation

Back 4

process of converting information in RNA into a sequence of amino acids to make proteins

Front 5

Condon

Back 5

set of three nitorgenous bases (letters) that makes an amino acid

Front 6

Mutation

Back 6

any change or error in DNA

Front 7

Mutagen

Back 7

anything that causes a change in DNA could be radiation (X-rays) chemicals or high temperatures

Front 8

Messanger RNA

Back 8

RNA that picks up information in nucleus from DNA and travels to the cytoplasm

Front 9

Ribosomal RNA

Back 9

RNA that makes ribosomes; helps make proteins

Front 10

Transfer RNA

Back 10

RNA that transports amino acids to the ribosomes to be assembeld into proteins
