<span>Messenger RNA (mRNA) molecules are long strands of RNA nucleotides that directribosomes to make proteins. They travel from the nucleus to the ribosome. Ribosomal RNA (rRNA) molecules make up part of the ribosomes of the cell in the cytoplasm. Transfer RNA (tRNA) molecules transport amino acids to the ribosomes.</span>
Pardon? I don’t understand the question
An organism that contains foreign DNA, which was inserted into its own genetic material, is called transgenic.
Pollen is a gamete therefore it contains half genetic information of a regular cell. all the possible combination types are S1T, S2T, S1t and S2t
An action potential will not occur unless the membrane potential AT THE VOLTAGE GATED SODIUM CHANNEL reaches a level called THRESHOLD.
An action potential refers to the change in the electrical potential which occurs as a result of the passage of impulses along the membrane of muscle cells or nerve cells. An action potential occurs when there is depolarization of the cell membrane to the threshold stage.
