Answer:

As a result of a change in the sequence of nucleotides in a strand of DNA (Deoxyribonucleic acid), the amino acids also change in the final protein which leads to protein malfunction.

Naddika [18.5K]

Answer:

Option-D

Explanation:

Plasmodesmata are the plasma membrane lined pores present in the cells of the plants. Inside these pores runs a closed tubelike structure which is an extension of the endoplasmic reticulum.

The plasmodesmata allows cell to cell communication which involves symplast mode of transport that is through its cytoplasm.

The small water soluble molecules like amino acid and sugars can easily pass through these plasmodesmata via diffusion. The large molecules can be transported through these plamodesmata through selective diffusion.

Thus, Option-D is the correct answer.

What is one way that a frameshift mutation could occur? (1 point)
erastovalidia [21]

Answer:

two nucleotides are deleted

Explanation:

Frameshift mutations arise when the normal sequence of codons is disrupted by the insertion or deletion of one or more nucleotides, provided that the number of nucleotides added or removed is not a multiple of three.

Because two nucleotides are deleted (2 is not divisble by 3), it would be a source of a frameshift mutation.

Hope this helped! :^)
