BIOMG 3300 Unit 6 Objectives Questions with
Correct Answers
purines Correct Answer-double ring structure, A and G
pyrimidines Correct Answer-single ring structure, C,U,T
pyrimidines and purines are hydrophilic or hydrophobic? Correct
Answer-hydrophobic
nucleotide Correct Answer-base, pentose, and 1 or more phosphats
nucleoside Correct Answer-nucleotide without the phosphate
structural difference between ribose and deoxyribe Correct Answer-
ribose has an OH on C2 while deoxyribose doesn't
What type of bond connects nitrogenous bases to C1 of sugars? Correct
Answer-N-B-glycosyl bond
What atom on a sugar does phosphate bind in DNA/RNA Correct
Answer-C5
sugar phosphate backbone (RNA and DNA) Correct Answer-alternating
chain of sugar and phosphate, negatively charged
, -starts with 1 phosphate connected to the 5'C of a sugar
-Ends with a sugar connected to phosphate via its 3'C
oligonucleotide Correct Answer-short nucleic acid with <50 nucleotides
polynucleotide Correct Answer-longer nucleic acid
What types are found in the base pairs between nitrogenous bases?
Correct Answer-H bonds
How many H bonds are between A and T Correct Answer-2
How many H bonds are between G and G? Correct Answer-3, this bond
is stronger and has a higher melting point as a result
Structure of DNA Correct Answer-2 helical DNA chains would in RH
double helix
-hydrophilic backbone faces outside
-hydrophobic bases face inwards, H bond to each other perpendicular to
axis
polarity of DNA strands Correct Answer-the strands run antiparallel.
Are said to be complementary to each other
