Cutting the ___________ bonds of the DNA.
Cutting the ___________ bonds of the DNA.
Which enzyme does the scissors simulate?
One RNA nucleotide
RNA production.
How many DNA strands are visible?
Which RNA nucleotide will be put into place next?
Which enzyme would do this in a real cell?
A more overall view of RNA production.
How many genes of DNA does this represent?
How many molecules of mRNA are being made here?
The finished mRNA, and the DNA put back together.
Which is the coding strand?
Which is the transcribed strand?
The mRNA is a copy of ( ~ the same as) the ______________ strand.
(Be careful here!)
How is the mRNA different ... not exactly the same?
The beginning of two mRNA molecules.
The mRNA strands from three different lab groups.
Why do they all start out the same?
How soon do they become different?
Why are they different?
What difference does it make that they are different?
Different amino acids.
How are they the same?
How are they different?
Where would this be in a real cell?
Out in the cytoplasm, making a polypeptide.
How many mRNA codons have already been "read" by the ribosome?
Can this tRNA carry an amino acid other than glycine?
Another tRNA is now at the ribosome.
What will happen next? (It looks like the ribosome is full.)
Which enzyme does this in a real cell?
The tape represents a ____________ bond. (There are two different and correct answers. Can you give both?)
What does the string of white papers represent? (Be careful; don't get
ahead of yourself.)
Part of the results from Groups 1, 2 and 3.
Be able to compare them and explain how and why they are alike
/ different.
