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
