GMOS TEST EXAM 2026 QUESTIONS AND
ANSWERS 100% PASS.
Plants can be genetically modified in a number of different ways. Select
all of the methods by which scientists are genetically modifying plants
......ANSWER......- Plasmids within the plant pathogen. Agrobacterium
tumefaciens, are used to introduce genes into a plant
- Small particles of genetically modified DNA coated in a metal are fired
by a gene gun into plant tissue
- Small pieces of RNA are used to silence the expression of specific
alleles
CRISPR is a tool used in genome editing. Which of the following
descriptions correctly describes how CRISPR may be used?
......ANSWER......- To remove and replace the gene of a soybean to
improve the quality of soybean oil
- To remove and replace the gene of a corn to increase the plant's
drought tolerance
- To treat human diseases by deleting and replacing harmful mutations
- To inactivate genes to determine the role of the gene in the target cell
Genes are the basic physical and functional unit of hereditary and
contain information that codes for a loss of a product
......ANSWER......False
pg. 1
,A gene consists of a long combination of five different nucleotide bases.
Different combinations of the nitrogenous bases give instructions for
different products ......ANSWER......False
Some genes act as instructions to make molecules called proteins
......ANSWER......True
Some genes do not code for proteins but instead RNA molecules
......ANSWER......True
While genes may contain information for a single trait, they often create
products that interact in complex biological pathways that may be
influenced by other genes ......ANSWER......True
Environmental conditions can influence the expression of a gene
......ANSWER......True
It is always a simple process to identify one gene associated with a
single trait ......ANSWER......False
DNA carries the instructions to produce molecules that carry out of all
of the functions of a cell required for life and ultimately determines the
chemical and physical characteristics of living organisms
......ANSWER......True
pg. 2
,In DNA, each molecule is encouraged by a gene a specific sequence of
carbohydrates that specify how a molecule is to be made
......ANSWER......False
The primary products of DNA are RNA and the arrangement of
nucleotides within a gene specifies the order and types of amino acids
that must be put together to make an RNA molecule
......ANSWER......False
Proteins are made of a long chain of chemicals called amino acids,
which are determined by the nitrogenous base sequence of nucleotides
......ANSWER......True
Th particular sequence of amino acids in the chain is what makes one
protein different from another ......ANSWER......True
General description of use of vector ......ANSWER......Genetic material is
introduced into a plant by using a plant bacterial pathogen
General description of particle bombardment ......ANSWER......Plant
cells are transformed by bombarding the tissue with the modified DNA
particles
General description of RNA interference ......ANSWER......Plant cells are
transformed by silencing existing genes
pg. 3
, Procedure of RNA interference ......ANSWER......Small pieces of RNA
molecules inhibit gene expression by neutralizing targeted mRNA
molecules
Procedure of particle bombardment ......ANSWER......With the use of a
gene gun, high velocity metal particles containing a gene of interest can
be transferred into the cell by penetrating the cell wall and cell
membrane of a plant. The DNA fragment will remain and become
incorporated into a plant's chromosome
Procedure of use of vector ......ANSWER......A new gene is inserted into
Agrobacterium and is used to infect a plant cell. The new gene is
transferred to the plant, and the infected plant cells are used to
produce new plants
Examples of use of vector ......ANSWER......Bt plants that provide
resistant to insect pests
Examples of particle bombardment ......ANSWER......wheat plants
Examples of RNA interference ......ANSWER......Artic apple
Description of herbicide tolerant plants ......ANSWER......renders the
plant resistant to RoundUp
pg. 4
