Unit 5 Dna Flashcards

Front 1

Double Helix

Back 1

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

Front 2

Nitrogenous Base

Back 2

Carbon ring structure found in DNA or RNA that contains on or more atoms of nitrogen, includes adienine, guanine, cytosine, thymine, and uracil

Front 3

Transcription

Back 3

process where an RNA copy of DNA is made; happens in the nucleus

Front 4

Translation

Back 4

changing the information in RNA into amino acids to make proteins

Front 5

Codon

Back 5

set of three nitrogenous bases (letters) that make and amino acid

Front 6

Mutation

Back 6

any change of 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

Messenger 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 assembled into proteins
