When COPYING DNA into RNA
DNA: A C T G C A T T G
mRNA: U G A C G U A A C
RNA does not have T’s, Instead has_’s (Uracil)
U
DNA sequences that DON’T tell how to make the protein are called _____s.
DNA sequences that DO tell how to make the protein care called _____s
INTRONS
EXONS
During the process of DNA being copied into RNA, both the introns and exons are copied into the mRNA (___-mRNA)
pre-mRNA
After the pre-RNA is formed, an enzyme then cuts the ____s out of the pre-mRNA and connects the ____s
introns
exons
After the exons are connected, The mRNA leaves the nucleus through a ______
pore
The 2nd part of protein synthesis is called ______
Translation
Translation occurs in the _____
Cytoplasm
At the beginning of translation, A ribosome attaches to the mRNA at the ______ _______
START CODON
The ribosome starts moving down the mRNA, reading 3 N-bases at a time (a _____)
Codon
each codon codes for a specific _____ ______
AMINO ACID
After the ribosome starts moving down the mRNA, A ___ brings the correct amino acid to the ribosome that the mRNA calls for
tRNA
During Translation the tRNA _______ matches up to mRNA _____
ANTICODON
CODON
After the tRNA brings the correct amino acid, The tRNA ____ ____ the amino acid to the ribosome
drops off
After the amino acid is dropped off, the ribosome moves on to the next ____ and the process repeats
codon
During Translation, tRNA’s keep bringing in the correct ____ _____s. The ribosome adds them to the growing amino acid ____.
amino acids
chain
