New cards
RNA
________- binding proteins can regulate alternative splicing by binding the proteins near splice sites that are regulated.
2
New cards
RNA molecules
________, in the nucleus and after getting exported from the cytoplasm, are associated with proteins.
3
New cards
Introns
________ are removed and it results in an A residue that is called a branch point.
4
New cards
360 kDa
________ (a cleavage and polyadenylation factor; made of four polypeptides) forms an unstable connection with the AAUAAA poly (A) signal.
5
New cards
MiRNAs
________ and siRNAs are made from longer precursor molecules and help with either repressing or cleaving target mRNAs.
6
New cards
Pre tRNA
________ can have some of its intron removed near the 5 sequence.
7
New cards
Micro RNAs
________ (miRNAs) can repress translations and this helps form hybrids in specific mRNAs.
8
New cards
amino acids
When it does occur, it causes a change in the ________ and results in proteins with different functions.
9
New cards
FG
________- nucleoporins (contain a hydrophobic sequence) help with the transport of macromolecules in nuclear pores.
10
New cards
pre mRNA
The ________ in the nucleus has its nucleotide sequence altered during RNA editing, though this doesnt happen often invertebrate animals.
11
New cards
Proteins
________ have a special amino acid sequence if they are imported or exported from the nucleus.
12
New cards
rRNA
5S ________ is synthesized while RNA polymerase III is not processed.
