Studied by 5 peoplewhat are nucleic acids responsible for?
storing genetic information
nucleic acids are made up of?
monomers
what are monomers
small molecules that bond together to create complex structures
draw a nucleotide
what do all bases contain
nitrogen
5 carbon sugars=
deoxyribose
what are the base and phosphate linked by ……. to pentose sugar
covalent bonds
what are the base’s linked by
hydrogen bonds
phosphate and pentose sugar link to each nucleotide forming
strong sugar-phosphate backbone
is RNA single stranded or double stranded
single stranded
what are the bases of DNA
adenine,cytosine,guanine,thymine
What are the bases of RNA
adenine,cytosine,guanine,uracil
what is teh number of sequences allowed
they are infinite
what shape does DNA have
double helix
A=T
C=G
complementary base pairing
when they run in opposite directions this is called
antiparallel
each end ends with something different want do they end with
phosphate group
deoxyribose
what happens when 2 strands go in the same direction
bases cant form hydrogen bonds with eachother
what are the differences between DNA and RNA
DNA: double stranded, A,C,T,G. the sugar= deoxyribose
RNA=single stranded ,A,C,U,G the sugar-ribose
what is the difference between deoxyribose and ribose sugar molecule
the OH and H on 2
what enzyme is used for transcription
RNA polymerase
Transcription
DNA is copied into mRNA
translation
forming polypeptide chain from mRNA
what is mRNA?
a copy of a single gene
when does translation happened
when strand leaves nucleus
