Your DNA is like a cook book that contains many chapters, why is this a good analogy.
The chromosome can be viewed like chapters with different information in/on each.
Each chapter contains sections that hold information much like genes on a chromosome
You can find and copy information needed from only the sections that you need rather than copying all of the information all of the time.
All of the above are examples that make the analogy work
Letter X is pointing to ....
Sugar - Ribose
Sugar - Deoxyribose
Sugar - Glucose
Phosphate
Letter Y is pointing to ....
Sugar - Ribose
Sugar - Deoxyribose
Sugar - Glucose
Phosphate
Letter X, Y and #1 make up ....
Nucleotide
Sugar phosphate backbone
Protein
DNA Polymerase
What does the term anti parallel refer to?
How nitrogenous bases pair.
The direction of the sugar-phosphate backbones
The position of the nitrogenous bases
How to hold a DNA model so X-rays can pass through
Which of the following best describe the term semi conservative DNA replication.
Two original strands of DNA combine and two new strands of DNA combine
One original strand of DNA with one new strand of DNA to form the helix
Parts of an original strand with parts of a new strand to form the new helix.
None of the above.
The diagram shows ____________ DNA replication.
prokaryotic
eukaryotic
bacterial
viral
If I want to make a protein, what is the correct order of processes?
