If a FRAMESHIFT mutation causes a stop codon to be inserted into the DNA sequence
a
the resulting protein may be too long and non-functional
b
the resulting protein may be too short and non-functional
c
the phenotype and genotype for the gene will remain unchanged
d
the resulting protein will not be affected
Question 25
Unlike photosynthesis, cellular respiration occurs in
a
all cells, all the time.
b
animal cells only.
c
all cell types, but plant cells.
d
plant cells only.
If a frameshift mutation causes a stop codon to be inserted into the DNA sequence, then:
b. the resulting protein may be too short and non-functional.
When a stop codon is introduced prematurely due to a frameshift mutation, the translation process is halted earlier than it should be. This results in a truncated protein that is usually non-functional or has an altered function.
As for the second question regarding cellular respiration:
a. all cells, all the time.
Cellular respiration occurs in the cells of all organisms, including plants, animals, fungi, and many microorganisms. This process helps cells convert nutrients into ATP, which is used as an energy source for cellular activities. Plants perform photosynthesis to produce glucose and oxygen, which can then be used in cellular respiration to generate ATP.
