130 Multiple choice questions

Term 1 of 130
4) According to The Daily Times article, what causes congenital hearing loss?

Nutritional deficiencies in the mother lead to congenital hearing loss.

Exposure to loud noises during pregnancy causes congenital hearing loss.

Sections of DNA, genes or chromosomes, contain instructions for making specific
proteins. These proteins determine human traits.

Genetic defects that affect the proper functioning of hairs cells inside the inner ear
cause congenital hearing loss.

Term 2 of 130
6) During codominance, which one is true?

Two alleles are equal, but instead of one dominating the other, both alleles show up at
once.

Alleles are inherited independently without interaction.

One allele completely masks the effect of another allele.


Only one allele is expressed in the phenotype.

Term 3 of 130
24) What is a gene's primary job?

transport nutrients across cell membranes


store energy for cellular activities

tell amino acids in what order they need to be arranged to make a specific type of
protein


break down waste products in the cell

,Term 4 of 130
12) An example of a beneficial mutation is ________.

a mutation that causes blindness


a complete absence of red blood cells

single allele for Sickle cell disease


a gene that leads to increased susceptibility to infections

Term 5 of 130
homozygous

alleles that can only be expressed in certain conditions

alleles that are completely unrelated to each other

one allele is dominant and the other is recessive


both alleles for a trait are the same (dominant or recessive)

Term 6 of 130
14) What were Mendel's results when he crossbred the purebred?

Through his experiments, he demonstrated that genetic traits can be predicted and that
traits are either dominant or recessive.

His work laid the ground for modern genetics.


He found that all of these crossbred offspring grew tall.
The short trait seemed to have disappeared

If a harmful gene is discovered, if can be removed and replaced with a healthy one.

Diseases are caused by defective genes in a person's body and this is an effective way of
curing diseases.

James Watson, Francis Crick

,Term 7 of 130
16) What is a nucleic acid?

a mineral that supports cellular structure


a type of carbohydrate that stores energy

a biological molecule necessary for life on earth

a synthetic compound used in laboratory experiments

Term 8 of 130
Define the term. Heredity

the transmission of genetic traits from parents to offspring


the breakdown of nutrients in the digestive system

the method by which cells generate energy

the process of creating new species through evolution

Term 9 of 130
8) Who developed the DNA model used today?

Hershey, Chase

Rosalind Franklin

Proteins, Dna

James Watson, Francis Crick

Term 10 of 130
2) What is a protein?

are the energy molecules that power cellular activities

are the structural components of cell membranes

determine an organism's characteristics; formed in ribosomes from instructions in genes

are the waste materials produced during metabolism

, Term 11 of 130
4) The definition of incomplete dominance is ___________.

when alleles do not interact with each other


when the alleles combine or blend together to produce a trait that is a combination of
the two

when alleles are completely dominant over others

when alleles are lost due to environmental factors

Term 12 of 130

carbohydrates

nucleic acids

proteins


lipids
