1

RNA

________- binding proteins can regulate alternative splicing by binding the proteins near splice sites that are regulated.

New cards
2

RNA molecules

________, in the nucleus and after getting exported from the cytoplasm, are associated with proteins.

New cards
3

Introns

________ are removed and it results in an A residue that is called a branch point.

New cards
4

360 kDa

________ (a cleavage and polyadenylation factor; made of four polypeptides) forms an unstable connection with the AAUAAA poly (A) signal.

New cards
5

MiRNAs

________ and siRNAs are made from longer precursor molecules and help with either repressing or cleaving target mRNAs.

New cards
6

Pre tRNA

________ can have some of its intron removed near the 5 sequence.

New cards
7

Micro RNAs

________ (miRNAs) can repress translations and this helps form hybrids in specific mRNAs.

New cards
8

amino acids

When it does occur, it causes a change in the ________ and results in proteins with different functions.

New cards
9

FG

________- nucleoporins (contain a hydrophobic sequence) help with the transport of macromolecules in nuclear pores.

New cards
10

pre mRNA

The ________ in the nucleus has its nucleotide sequence altered during RNA editing, though this doesnt happen often invertebrate animals.

New cards
11

Proteins

________ have a special amino acid sequence if they are imported or exported from the nucleus.

New cards
12
