protein synthesis Flashcards
The Hershey-Chase Experiment
They collaborated in studying viruses, nonliving particles smaller than a cell that can infect living organisms
What did Avery discover?
The nucleic acid DNA stores and transmits the genetic info from one generation of an organism to the next
what 2 molecules are on the side of the double helix?
- ribose
* phosphate group
3 types of RNA & function?
mRNA : blueprint
tRNA : chef (amino acid)
rRNA: connects them into a protein
DNA > RNA??
transcription
RNA > protein??
translation
Where is the mRNA located?
nucleus
what 2 types of mutations?
gene and chromosomal mutations
3 main difference between RNA and DNA
- the sugar in RNA id ribose
- RNA is generally single stranded
- RNA contains uracil in a place of thymine
what is the one job most RNA molecules are involved?
protein synthesis
what is a codon?
consists of 3 consecutive nucleotides that specifies single amino acids
where does translation take place?
on ribosomes
what happens during the process of translation?
the cell used info from mRNA to produce proteins
what is anticodon?
each tRNA has unpaired bases
