DNA & RNA (mRNA&tRNA) Flashcards
1
Q
since DNA cannot leave the nucleus, how does the ribosomes synthesize proteins
A
it’s copied & carried to the cytoplasm where the ribosomes are found
2
Q
what copies the DNA to bring to the ribosomes
A
mRNA (messenger RNA)
3
Q
what is different about the RNA strand from them DNA strand
A
no thymine, instead uracile (U)
4
Q
what is the sugar called in the RNA strand
A
ribose
5
Q
where does tRNA (transfer RNA) only exist
A
cytoplasm
6
Q
