Transcription
Process of interpreting mRNA to sequence of amino acids/proteins
____ # of bases encode for ___ # of different amino acids
4; 20
_ __ is read in a triple codon reading frame
mRNA
The TATA box is necessary for initiation of transcription and is located on the
DNA strand (t/f)
True
What enzyme is responsible for converting a DNA strand into RNA?
RNA polymerase
Pre-mRNA may undergo what modifications?
5' cap, poly-A tail, splicing
, What is the role of tRNA in the cell?
Transferee amino acids from cytosol to the growing amino acid chain.
Which RNA molecules are responsible for transferring amino acids during
translation?
tRNA
Why is the amino acid methionine (met) added at initiation of translation?
Because the start codon is AUG (the triplet code for methionine), which
signals the start of the coding region
Amino acids are added to the:
C-terminus end
After a stop codon is encountered, the hydrolysis of what molecule aids in
releasing the new polypeptide chain?
Water
post-translational modifications are necessary to ensure ___
Unique folding/appropriate structure shape
