The answer that describes the sentence above in which is a segment of DNA that are being coded in means of making one type of protein molecule is known as the gene. The gene is considered to be a unit that is physical and function responsible for heredity.

Answer: The correct answer for the filling the blank is Gene.

Gene is a segment of DNA present in the genome of an organism. It carries information for the specific characteristics of the organism. It is also known as heredity unit as the information is carried from one generation to the next.

Two processes take place for gene expression. These are Transcription and Translation.

In transcription, DNA of the gene is converted to mRNA ( messenger RNA). A gene has a transcription start site from where transcription begins and a transcription stop site, which terminates transcription. mRNA contains start codon and stop codon for the initiation and termination of translation.

The translation of mRNA gives specific protein. Since the sequence of genes are very specific, therefore, one type of protein is coded by one gene.

kobusy [5.1K]

In a reflex arc, after a sensory nerve signal is processed by interneurons in the integration center, the signal goes to the motor neuron. The answer is motor neurons.

<h3>What is the reflex arc?</h3>

The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts.

In general terms,

1) A stimulus of varying nature reaches the body.

2) The peripheric nervous system -PNS- receives the stimulus and sends this information to the central nervous system -CNS-.

3) The CNS processes the information and sends another signal as a response to the stimulus.

Five elements compose the reflex arc, which are receptors, three types of neurons, and effectors.

The neurons involved in the mechanism are:

• Afferent or sensorial neurons

• Interneurons

• Efferent or motor neurons

Mode of Action:

Ascending branch

The stimulus reaches the body and is received by the specialized sensory receptors.

Afferent neurons, placed in the dermis and epidermis, receive this information from receptors, react and send it to the central nervous system as nerve impulses.

Descending branch

Interneurons in the CNS, process the information and send a motor response.

Efferent neurons carry the response from the CNS to the effector organs, which might be either a muscle or a gland.

Finally, the target tissue responds to the stimulus as a contraction -muscle-,or as hormones release -gland-.

A motor neuron is formed by a cellular body, dendrites (cytoplasmic extensions that receive stimuli from other cells), and a long axon that is capable of conducting the electrochemical signals.

The axon brunches out into several extensions when it approaches the muscle.

At the end of each brunch, the axon is inserted in the muscle fiber surface, composing neuromuscular join.

This is the last part of the NS involved in the process before the muscle contracts.

After a sensory nerve signal is processed by interneurons in the integration center, the signal goes to the motor neuron, and from there to the effector.

The corrct answer is motorneuron.

Circle two reasons why gene expression is regulated in prokaryotic cells

MissTica

Gene expression is the process which the cell response to change. Since the Prokaryotic transcription and translation occur simultaneously in the cytoplasm, and regulation occurs at the transcriptional level is the two reasons.
