What kind of mutation would occur if a sequence of DNA is changed from ATCGGCTTAACG to ATCGGCTAAACG?
Zinaida [17]

Answer:

Base substitution mutation

Explanation:

Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:

ATCGGCTTAACG to ATCGGCTAAACG

This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.

A thermosensory neuron in the skin converts heat energy to nerve impulses via a conversion called _____.A. sensation
pshichka [43]

Answer:

Sensory transduction

Explanation:

Sensory transduction is a process by which the sensory neuron transforms the obtained sensory information into an electric signal. Sensory neurons are the afferent neurons and are activated when they receive stimulus from a sensory receptor. This is followed by the firing of action potential to convey the sensory information into the CNS through the cranial or spinal nerve.

Change in temperature serves as a stimulus for thermosensory neurons present in the skin. The activated thermosensory neuron then produces an electric signal by the process of sensory transduction during which a nerve impulse is generated and action potential to convey the information.
