- Q1
Which molecule is composed of two chains which coil around each other to form a double helix carrying the genetic instruction used in the growth and development of living organism?
Amino Acid
Protein
RNA
DNA
60s - Q2
Why is DNA called the "blueprint of life"?
Because it is like a fingerprint
Because it can relay messages to other molecules
Because it has a blue color
Because it contains the instructions for building an organism
60s - Q3
What is the shape of a DNA molecule?
Round
Circular
Double-helical
Straight
60s - Q4
Which of the following is NOT a component of a DNA nucleotide?
Deoxyribose sugar
Carbon dioxide
Phosphate group
Nitrogenous base
60s - Q5
The DNA has a double – helix structure forming a twisted ladder. The backbone and steps of the ladder is composed of individual nucleotides bonded together. What are the important biological compounds that make up the backbone of the DNA molecule?
Pentose sugar
Nitrogen bases
Pentose sugar and phosphate group
Phosphate group
60s - Q6
Which is NOT TRUE about a DNA nucleotide?
It has a phosphate group.
It contains a nitrogen base.
It contains two or more nitrogen bases.
It has a pentose or 5-carbon sugar compound.
60s - Q7
Which of the following pairs of nitrogenous bases is correct?
Guanine and Thymine
Cytosine and Thymine
Adenine and Guanine
Adenine and Thymine
60s - Q8
Bases in a DNA are complementary. Which is true of its complementary base if there are 35 Thymine in the DNA strands?
Cannot be determined
There will be 35 Guanine bases
There will be 35 Adenine bases
There will only be 25 Adenine, since a DNA is helical
60s - Q9
Bases in a DNA are complementary. Which is true about complementary base pairing if there are 20 Guanine in the DNA strand?
Cannot be determined
There will be 20 Cytosine bases
There will be 20 Adenine bases
Only 10 Cytosine, since its helical
