Protein synthesis actually begins in the nucleus when transcribes a single gene on the dna molecule is copied. the process of copying this gene is called this copy is known as and contains the protein building instructions. this copy is sent out into the cytoplasm to the part of the cell known as the the of the ribosome will join together to form a functional ribosome when they attach to the mrna. as the mrna moves through the ribosome, the message is read by transfer rna brings the correct back to the ribosome. the amino acids are placed in the correct order and are hitched together by

The function of the excretory system is to control homeostasis and

Ts assignment - snow day assignment genetic variation and natural selection natural selection relies on genetic variation. in any population of beetles, there are alleles for brown or green color. what happens to the genotype and the phenotype of the beetle population when there are distinct advantages and disadvantages due to color? order the steps that take place during natural selection in this beetle population.
