How does a template strand of DNA code for an aminó acid? (Can you list all the steps?)
frosja888 [35]

Answer:

The template strand is the antisense strand or non-coding strand with polarity in the direction of 3' to 5' end which codes for the primary RNA molecule.

The template strand codes for the proteins through transcription and translation. The transcription creates a copy of the sense strand in the form of RNA as RNA polymerase binds the promoter and adds nucleotides in 3' to 5' direction.

The mRNA molecule formed as a result of transcription contains code in the form of codon or triplets of nitrogenous bases which are read by the ribosomes and specific amino acids are added to the growing polypeptide chain via tRNA molecule.

Thus, a template strand codes for amino acids.

what describes a method by which the body prevents airborne pathogens from entering the lungs during respiration?
mihalych1998 [28]

The statement that describes a method by which the body prevents airborne pathogens from entering the lungs during respiration is as follows: the mucus in the nose traps microscopic particles and bacteria while nose hairs filter out larger particles.

<h3>What is the role of the lungs?</h3>

The lungs are biological organs of vertebrates that controls breathing and oxygenates the blood.

The lungs is the major breathing organ of the body and is connected to the nose through a pipe called trachea and bronchi.

However, to prevent unwanted or foreign particles in the atmosphere from entering into the lungs, the mucus in the nose helps trap the microscopic particles while the hairs in the nose blocks the passage of larger particles.
