30 Cards in this Set

  • Front
  • Back
all living things use
protein
dna is made of
phosphate group,deoxyribose sugar, nitrogenous base
2-ring purine
adenine and guanine
1-ring pyrimidine
cytosine and thymine
james watson and francis crick
came up with theory on how they thought dna functioned
rosalind franklin
pictures/x-rays of inside of nucleus
human genome project
decoding of human's DNA
ventor
worked with watson and then broke off
nucleotides
bonded together by condensation, covalent bond, phosphate/deoxyribose
double helix
dna's twisted shape
replication
dna in the chromosome is copied
transcription
dna makes rna
proteins
build new cells, repair cells and everything is transported, all enzymes
rna differs from dna because of
dna is double-stranded, dna is a deoxyribose sugar, 4 nitrogenous base
3 types of rna
messenger,ribosomal, and transfer
messenger rna
brings info from the dna to the ribosome,dna makes it,transcription,mRNA
ribosomal rna
goes to the ribosome,make enzyme that allows amino acid to bond, rRNA, assembles acids in the right order
transfer rna
brings amino acids to the ribosome, tRNA
triplicate code
3 nitrogenous bases to make 1 amino acid
translation
process of converting the info in a sequence of nitrogen bases in mRNA into a sequence of amino acids that make up a protein
takes place in the ribosomes/peptide bond
translation
deletion
chunk of chromosome is broken out
insertion
same sister chromatd
inversion
chunk breaks off a chromosome/turns around and goes back in
translocation
genetic information goes across, breaks off one chromosome and locates it across to a different chromosome
cause of mutation
gamma kudiation
chemicals: benzene, asbestos
cause
cause
high temperature
x-rays, cosmic rays, nuclear radiation, ultra-violet rays
cause
cause
spontaneous mutation
