Agroup of plant cells was exposed to radiation, which damaged the chloroplasts and caused them to lose function. if the mitochondria were unharmed, what would happen to the overall function of the plant cells? a. the cells would not be able to release energy from biomolecules, but would be able to make food. b. the cells would not be able to break down waste, but would be able to replicate dna. c. the cells would not be able to make food, but would be able to release energy from biomolecules. d. the cells would not be able to replicate dna, but would be able to break down waste.

The correct answer will be option C.

Explanation:

Chloroplasts are the organelle which is involved in the process of photosynthesis, the process by which food is made in the plant cell while mitochondria is an organelle which is associated with the formation of ATP molecules from substrate and release of energy.

According to the question, radiation caused the loss of function of chloroplast but not harmed the mitochondria it means that plant will not be able to perform photosynthesis and synthesize the food but it will have its mitochondria functional which perform cellular respiration and hence produce energy either by the breakdown of proteins or fatty acids.

Thus, option C is the correct answer.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
