Endocytosis is a term used to describe a process of active transport that facilitates the movement of particles such as molecules and parts of a cell or the whole cell into a cell.The best scenario for the process occurs when a cell needs to pass/transport molecules that are large and cannot move through the membrane passively.
Answer:
The correct answer is 1377.
Explanation:
Peptides and proteins are made in the process of Translation. For this to happen, a molecule of mRNA containing a nucleotide sequence is read by a structure called ribosome. Each group of three nucleotides from the mRNA form a codon, and each codon has an anticodon in the tRNA molecule that will ultimately code for a specific amino acid (except for stop codons -when they appear in the sequence, translation stops-). <u>Taking all of this into consideration, if 3 nucleotides lead to 1 amino acid, to have a 459-amino acid polypeptide it would require 1377 nucleotides (without counting the 3 nucleotides from the stop codon)</u>.
Answer:
heyooooooooo!!
The outer layers of the star fall inward on the neutron core, thereby crushing it further. The core heats to billions of degrees and explodes (supernova), thereby releasing large amounts of energy and material into space.
