dna contains directions to make
proteins
dna is found in the
nucleus
dna is used to transfer genetic information from
nucleus to ribosomes
dna is a type of organic compound known as a
nucleic acid
dnas building blocks are
nucleotides
nucleotides are made of a
sugar, phosphate, nitrogen base
dna has 2 strands and is referred to as
double stranded
dna has 2 strands and is called
double helix
there are 4 nitrogen bases in dna
a-t g-c
the two strands of dna are held together by
weak hydrogen bonds
backbone sides of dna
phosphate and sugar
steps are nitrogen based pairs
a-t g-c
dna is made of segments called
genes
contains the code or directions for one protein to be made
gene
genes are made up of
nucleutides
determines the expression of the gene
nitrogen
for the protein to be made the dna must be changed to
mrna first
leaves the nucleus and go to the ribosomes with the diredctions for protein synthesis
mrna
codes for a specific order of amino acids which are the building blocks of protein
mrna
dna is short for
deoxyribonucleic acid
DNA has how many strands?
two
dna has sugar in its nucleotides
deoxyribose
dnas bases in its nucleotides
a-t g-c
dna
contains directions to make proteins
rna is short for
ribonucleic acid
RNA has how many strands?
one
rna sugar in its nucleotides
ribose
RNA nitrogen bases
A, U, G, C
mrna
copy of dna instructions
delivers code to ribosomes
trna
brings/transfers amino acids to ribosomes for protein synthesis
rrna
at ribosomes/ put amino acids together with peptide bonds
change in the organisms dna
mutation
lead to a different protein no protein or excessive proteins to be generated
mutation
caused by carcinogens such as uv radiation and chemicals from smoking cigarettes
mutations are
