DNA Flashcards
DNA replication
copies DNA
Transcription
converts DNA into mRNA
Translation
interprets mRNA into a string of amino acids (proteins) tRNA (MAKING OF A PROTEIN)
Where do the 3 processes occur in prokaryotic cells?
cytoplasm, no nucleus
Where does replication and transcription occur in eukaryotic cells?
nucleus (where chromosomes are located)
where does translation occur in eukaryotic cells?
ribosomes, (in the cytoplasm)
what 3 ways does RNA differ from DNA
sugar=ribose
uracil base
single strand
mRNA function
carries instructions from a gene to make a protein, code for codons
rRNA
builds proteins, protein synthesis
tRNA
transfers amino acids to the ribosomes to make a protein, anticodons (more similar to DNA)
codon consists of how many nucleotides for an amino acid?
three
which RNA do you use to find the codon for an amino acid?
mRNA
what is an anticodon
3 nucleotides on tRNA
mRNA is the same as what anti or codon?
codon
tRNA is the same as what anti or codon?
anticodon
what is the flow of protein synthesis?
DNA -> RNA -> protein
what organelle assists tRNA translating the mRNA in the cytoplasm?
ribosome
the role of tRNA is to carry what?
an amino acid
tRNA anticodon is more similar to DNA or RNA in nucleotide sequence?
DNA
what is the first step of protein synthesis? where does it occur?
transcription
nucleus
what is the second step in protein synthesis? where does it occur?
translation
cytoplasm
what is the enzyme that creates mRNA from a DNA sequence ?
RNA polymerase
each codon of mRNA codes for?
amino acid
specific amino acid carried by tRNA is determined by what?
its anticodon
consists of a single strand of nucleotides
RNA
made of nucleotides linked together
both RNA & DNA
contains deoxyribose
DNA
has the nitrogen base uracil
RNA
contains ribose
RNA
is a nucleic acid
both RNA & DNA
