Announcements
I will not be available this afternoon after
school.
Lab 6C – Protein SynthesisQuestion 2 – replication happens in the nucleus
Question 3 – transcription happens in the nucleusQuestion 4 – DNA contains deoxyribose sugar, has the nucleotide base
thymine, is double stranded, and contains the life “code.”RNA contains ribose sugar, has the nucleotide base uracil, is single
stranded, and reads the DNA code.Both DNA and RNA are nucleic acids, have the nucleotide bases adenine, guanine, and cytosine, and both are synthesized in the
nucleus of a cell.
Things You Need to RememberAmino acids are the building blocks of proteins.
A mutation is a change in DNA.
If you create a mutation in the DNA sequence by changing ATG to ATT, you will change the mRNA codon, which will change the amino acid. The result will be a STOP codon inserted after methionine. Consequently, the
protein will be incomplete and work improperly, if at all.
If you were not in class yesterday, please go to table J, K or L and do labs 12A and 12C. If you need to complete the labs we did on Monday
and Tuesday, they are on tables G, H, and IThen do the exercise listed below.
