2. What type of chemical bond holds the DNAnucleotide bases, hence the 2 strands ofDNA, together?
3. What might be the advantages of using mRNA as anintermediary between DNA and protein?
4. For a human (genomic, chromosomal) DNA extraction (likewe did during week 2), match the outcomes on the left with theprocedures on the right. We started by isolating cells containingDNA by chewing the inside of our cheeks and spitting in a tube.

Dissolve cell membranes
[ Choose] Addprotease (meat tenderizer) Layer alcohol over cell extract Add salt Mix in detergent
Make DNA less soluble in water and less repulsive to itself
[ Choose] Addprotease (meat tenderizer) Layer alcohol over cell extract Add salt Mix in detergent

5. The DNA “building blocks” arecalled nucleotides. Briefly describe how DNA replication usescomplementary base paring to createnew DNA helices.
6. Which statement about transcriptionis false?
Group of answer choices
It's based on the same complementary base pairing used in DNAreplication except A binds to U instead of T.
Transcription is the processes of creating RNA from all the DNAin our genome.
Genes must be transcribed into a single-stranded RNA becauseit's the RNA that gets translated to protein
The promoter is the region on DNA where RNA polymerase startstranscribing a gene.
7. Is there a distinction between DNA and a gene? Howare they related? Explain your answer.
