Biology Ch. 10
DNA
DNA | deoxyribonucleic acid |
Copying of DNA | replication |
3 parts of nucleotide | sugar, phosphate, and base |
shape of DNA | double helix |
4 nitrogen bases | adenine, guanine, cytosine, and thymine |
error rate | 1 in a billion |
DNA sugar | deoxyribose |
Complementary Base Pairing Rule | G to C and T to A (vice versa) |
unzips DNA | heliocase |
bases with 2 rings of carbon | adenine and guamine |
RNA with a single uncoiled chain | messenger RNA (mRNA) |
RNA with a hairpin shape | transfer RNA (tRNA) |
RNA with a globular shape | ribosomal RNA (rRNA) |
3 mRNA nucleotides | codon |
AUG = | start codon |
UAA, UAG, UGA = | stop codon |
process by which genetic information is copied from DNA to RNA | transcription |
also called the production of proteins | protein synthesis |
a correlation between a nucleotide sequence and an amino acid sequence | genetic code |
the sugar is ribose, thymine is NOT present, but uracil is, single stranded | how RNA is different from DNA |
type of RNA that moves through the pores of the nuclear membrane into the cytoplasm | messenger RNA (mRNA) |
sequence of 3 nucleotides opposite of the site where amino acids attach | anticodon |
number of binding sites that ribosomes have | 3 |
suggested model of double helix for DNA | Watson and Crick |
bond that holds two bases together in the middle | hydrogen bond |
heliocases are known as | separating enzymes |
enzymes that bind to the separated chains of DNA | DNA polymerase |
determines the structure and function of the cell | amount and kinds of proteins |
proteins are | polymers |
each codon codes for a specific | amino acid |
