What does each mrna molecule that goes to the ribosomes dictate
ahrayia [7]

Answer:

mRNA or messenger RNA goes to ribosomes to dictate the genetic information that it contains .

Explanation:

Ribosomes act as work benches during protein biosynthesis.mRNA also called messenger RNA binds with the smaller subunit of ribosome at the time of translation.

       The bound subunit of ribosome reads the genetic information as codons containing three concecuetive nucleotides present in mRNA thus helping tRNA to bring the particular amino acid specific for that codon at the A site or attachment site of ribosome.

      Thereafter ribosome moves to the next codon to bring another amino acid and so forth.

       Thus mRNA helps ribosome to brings the amino acids at the translation site.

Ian waterman was able to sense pain and temperature because his _____ pathway was intact, but could not feel touch and limb posi
ANEK [815]
<span>Ian Waterman was able to sense pain and temperature because his spinothalamic pathway was intact, but could not feel touch and limb position because of damage to his lemniscus pathway. </span>

The lateral spinothalamic tract is a sensory pathway which carries sensory information like pain and temperature to the brain, across the thalamus. Free nerve endings which are located in the peripheral tissues are sensitive to cell damage. Those are primary neurons and they pass the sensory signal. Primary neurons synapse with secondary which are located in the spinal cord (white matter). These secondary neurons will ascend through the brainstem, medulla oblongata, pons and midbrain, until synapsing in the ventroposteriorlateral (VPL) nucleus of the thalamus. From the thalamus, the information is sent to cortex (somatosensory cortex).

Posterior column-medial lemniscus pathway is ascending spinal tract, carrying sensory information to the brain (sensory pathway). It conducts localized sensations of fine touch, vibration and proprioception (position sense) from the skin and extremities (muscles) to the central nervous system (cerebral cortex).

A macrophage may engulf a pathogen by endocytosis, which involves the reorganization of actin microfilaments in the membrane and microtubules in the cytoskeleton.

<h3>What is endocytosis?</h3>

Endocytosis is a cellular process by which a cell can absorb materials from the surrounding medium, such as viruses and bacteria in the case of macrophages.

Microfilaments and microtubules are proteins that form part of the cytoskeleton and dynamic conformational changes of them are associated with the cytoskeletal rearregement during the phagocytic process.

The actin microfilaments in the membrane and microtubules in the cytoskeleton form part of the process of endocytosis because they need to reorganize during cell movement.

In conclusion, a macrophage may engulf a pathogen by endocytosis, which involves the reorganization of actin microfilaments in the membrane and microtubules in the cytoskeleton.
