GMOS REVIEW SHEET QUESTIONS 2026
VERIFIED ANSWERS
◉ location in the cell of transcription. Answer: occurs in the nucleus
◉ location in the cell of translation. Answer: occurs in the cytosol
◉ the unintended effects of genetically modified plants on non-target
species has. Answer: positively impacted non-targeted insect species
due the reduction in the use of chemical insecticides
◉ a potential risk of genetically modified plants is that the genetic
engineering process could cause unnatural changes in the plant and
result in the unexpected production of protein in food. Which of the
following processes should be used to provide information on food
safety?. Answer: if the genetically engineered plant has a transgenic
protein that is similar to a protein already known to be an allergen. It
should be tested in people who have an allergy to the related protein
◉ RNA interference (RNAi) is a promising gene regulatory approach
in the functional genomics that has significant impact on crop
improvement. Which of the following descriptions correctly describes
RNA interference. Answer: a post transcriptional gene silencing
pathway triggered by a double-stranded RNA molecules to prevent
the expression of specific genes
, ◉ which of the following descriptions correctly describes the goal of
the genome editing technique, CRISPR?. Answer: to use enzymes to
target a specific DNA sequence and enable the removal and
replacement of the sequence
◉ which of the following techniques is used to intentionally
introduce changes into the DNA sequence to analyze gene function
and gene products?. Answer: mutagenesis
◉ DNA is made up of organic molecules called _________. Each
monomer contains a phosphate group, a _____ group, and a nitrogen
base. There are four types of monomers: adenine (A), ____, guanine
(G), and cytosine (C). Answer: nucleotides ; sugar ; thymine (T)
◉ the organization of these four different nucleotides is what
determines DNA's instructions, or ________. Answer: genetic code
◉ similar to the way the order of letters in the alphabet can be used
to form a word, the order of _______________ in a DNA sequence
forms genes, which tells cells how to make ____ and proteins.
Answer: nitrogenous bases ; RNA
◉ the ______________ are attached together to form two long
strands that spiral to create a structure called a _________. Answer:
nucleotides ; double helix
, ◉ think of the double helix structure as a ladder. The ________ and
sugar molecules serve as the sides of ladder and the ___________ are
the rungs. Answer: phosphate ;nitrogenous bases
◉ the two strands of the DNA molecule pair the bases on one strand
pair with the bases on another strand. This pairing is _________
meaning the adenine pairs with thymine, and guanine pairs with
_______. Answer: complementary ; cytosine
◉ these bases are connected weakly by chemical bonds called
______ bonds. Answer: hydrogen
◉ this pairing plays an important role in how ____ contains
information. Answer: DNA
◉ select the following characteristics that allow plants to survive and
reproduce in a land environment. Answer: - develop a means to
prevent their cells and tissues from drying out
- develop a system to transport water and nutrients to their cells
- reproductive structures had to change to disperse gametes in the
absence of water
- protect their embryos from the temperature and moisture variations
of life on land
◉ golden rice is a variety of rice that was genetically engineered to
synthesize beta carotene, a precursor vitamin B, in the edible parts of
the rice plant. Answer: false
, ◉ the purpose of golden rice was to produce a fortified food to be
grown and consumed in areas with vitamin deficiencies. Answer: true
◉ used in many societies for an energy source, rice is effective for
targeting vitamin deficiencies compared to expensive alternatives like
supplements of other consumable products. Answer: true
◉ researchers inserted two beta-carotene synthesis genes, one from
lilies and one from a soil bacterium, into the genome of rice. Answer:
false
◉ research has confirmed that golden rice yields low amounts of beta
carotene and is an ineffective source of vitamins for humans to
consume. Answer: false
◉ golden rice was introduced as a potential consumable food in 2000
but was not put into production until 2013 due to manufactures being
met with strong opposition from various activists. Answer: true
◉ Due to the low projections concerning human population growth
and the unlimited amount of farmable land, there is a need to
increase crop yield to provide food to the growing population in
developed and developing nations.. Answer: False
◉ Selective breeding provides a quicker and more precise way to
achieve certain desirable traits in crops in one generation rather
