pro synthesis review Flashcards
purines
double ring base
(a and g)
pyrimidines
single ring base
(c,t,u)
what is transcription
produces rna and dna
codon
triplet code on mRNA
anticodon
on tRNA and complimentary to mRNA
what is recombinant dna
2 sources of dna combined to make plasmid
genetic code
code for life
translation
makes protein from dna message
messager rna does?
send messages to ribosomes
ribosomal rna
makes up ribosome
transfer rna
transports amino acid to ribosomes
nucleotides are made of
sugar phosphate and base
what is dna replication when it uses an old strand and makes a new one
semiconservatived replication
mutations changes what
the sequence of nucleotides in dna molecules
each trna has a
anti codon and amino acid at one end
the backbone of dna is made of
phosphate and sugar held by covalent bonds
the rings of the rna ladder are made of
base and held by H bonds
what’s the difference between rna and dna
single stranded, uracil, no helix and ribs or sugar
ribosomes
site of protein synthesis
ribosome are made of
rrna and protein
three parts of translation
initiation, enlongation and termination
mutations cause
genetic diseases
what are some mutagens
sunlight, x-rays and pesticides
nucleotides in dna are bonded by
covalent bonds
nitrogenous bases in dna are bonded by
hydrogen binds
iwhat is the start code
methionine
what is a promotor
control the binding of RNA polymerase to DNA
what happens in imitation
ribosomes formed-mRNA feeds through the ribosomes and methionine start’s process
what happens in enlongation
tRNA delivers amino acids and chain is growing
what happens in termination
stop code terminates the growth- mRNA breakdowns and ribosome disintegrates
