What is needed for translation to occur? check all that apply. mrna ribosome trna codons

The correct answer is all of them,  "mRNA", "ribosome", "tRNA", and "codons".

Explanation:

In biology, translation is the molecular process at which genetic information is expressed into proteins that exert the biological functions. In order that translation occurs, a messenger RNA (mRNA) is needed, which carries the information from the genome to the ribosome, the organelle that catalyzes the translation process. In the ribosome, the protein is synthesized using transfer RNA (tRNA) molecules that carry amino acids according to the mRNA sequence defined by codons: triplets of nucleic acids specific for each amino acid.

-mRNA

-ribosome

-tRNA

-codons

Explanation:

The genetic code is described as a degenerate, because a single amino acid may be coded for more than one codon. There is also specific codons that signal the start and end of translation.

answer: the blood-brain barrier is a layer of specialized membranes and cell processes designed to keep undesirable substances from passing from the bloodstream into the precious tissues of the brain. while the blood-brain barrier does keep most bad things out of the central nervous system, it is not impermeable.

explanation:

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
