1.
DNA Provides the blueprint for the synthesis of proteins. A _____ is a segment of DNA that codes for one particular protein.
a)
Chromosome
b)
Trait
c)
Gene
d)
Genome
2.
The DNA sequences that make up the genetic code of an organism determine which traits the organism will exhibit.
How are the instructions coded by DNA translated into an organism's physical traits?
How are the instructions coded by DNA translated into an organism's physical traits?
a)
Instructions coded by DNA translated into proteins which express an organism's physical traits.
b)
Instructions coded by DNA sequences are translated into nucleotides which express an organism's physical traits.
c)
DNA sequences both code genetic instructions within an organism and express an organism's physical traits.
d)
DNA sequences that code for genetic instructions attach to phosphate groups that express an organism's physical traits.
3.
Which of these is true about DNA, proteins, and the expression of genetic traits?
a)
Proteins bind to DNA, which activates them and forces them to express certain traits.
b)
Enzymes break down DNA, releasing amino acids that join to form proteins and express various traits.
c)
DNA is mutated by a chemical passed from parents to offspring to form proteins that express traits.
d)
Genes in DNA code for the production of proteins, which cause traits to be expressed.
4.
What is the role of deoxyribonucleic acid in organisms?
a)
It is the controller of substances entering and exiting a cell through the cellular membrane.
b)
It is the cell's method of storage and transmission of genetic material.
c)
It is the filter of the cell's cytoplasm, keeping the cell free of waste.
d)
It is the messenger between RNA and the protein-synthesis ribosomes.
5.
All the information necessary for an organism to form and grow is recorded in the organism's DNA. How does DNA use its stored information to express a trait?
a)
Codons in the DNA simulate the DNA to replicate.
b)
Every time the DNA replicates, traits are expressed.
c)
The nucleotides in the DNA bind with amino acids in order to direct the cell's functions.
d)
The genes in the DNA instruct the cell to synthesize proteins.
6.
Nucleic acids are on the of the four major macromolecules.
The main function of nucleic acids is to
The main function of nucleic acids is to
a)
carry genetic material that helps to create structures inside the cell.
b)
act as enzymes, cell signals, and structural support for the cell.
c)
absorb energy from the Sun and transport it around the cell.
d)
aid in development, the immune system, and blood clotting.
7.

b)
Ile, Pro, Leu, Cys, Glu
c)
Met, Pro, Thr, Trp, Asp
d)
Ile, Gln, Lys, Stop, Glu
8.
A polypeptide chain folds to become a protein with a compact, 3-D structure.
The final shape of a protein is determined by the sequence of its amino acids. What determines this amino acid sequence?
The final shape of a protein is determined by the sequence of its amino acids. What determines this amino acid sequence?
a)
the number of nucleotides in the polypeptide
b)
the sequence of nucleotides in the polypeptide
c)
the sequence of nucleotides in the DNA template
d)
the number of nucleotides in the DNA template
9.

a)
RNA → Proteins → DNA
b)
DNA → RNA → Proteins
c)
DNA → Proteins → RNA
d)
Proteins → RNA → DNA
