Answer:

The correct answer is the AUGACCCACCCGA sequence.

Explanation:

A frameshift mutation occurs when a mutation caused an insertion or deletion in a specific gene sequence that shifts the way the sequence is read. The deletion or insertion can change the reading frame that results in a different translation from the original because of the triplet nature of the codons.

A frameshift mutation is caused by deletion or insertion of a number of nucleotides in a DNA sequence that is not multiple of three. In AUGACCCACCCGA insertion of a nucleotide caused frameshift mutation.

Thus, the correct answer is the AUGACCCACCCGA sequence.

Which description properly describes the plant structures involved in photosynthesis? Stomata take in water, sunlight, and carbo
erma4kov [3.2K]
The correct answer is that "xylem transports water, stomata take in carbon dioxide, and chlorophyll absorbs sunlight." The xylem is a vascular structure in plants that transport water, the phloem is another vascular structure in plants that transport nutrients. The stomata (singular; stoma) is the one responsible for the plants' gas exchange (takes in carbon dioxide, releases oxygen). The chlorophyll is what makes the green pigment of the leaves and mostly because of the presence of chloroplasts, the organelle in plant cells responsible for photosynthesis.
