Answer:
e. All of the above are False.
Explanation:
A tRNA is a transfer RNA that carries amino acid from the cell pool to the mRNA-ribosome complex. The anticodon sequence of tRNA is complementary to the mRNA codons and bind to the respective amino acids. None of the tRNA has anticodon for stop codons and therefore, as soon as the ribosome reaches stop codon, protein translation terminates.
AUG is the initiation codon for protein synthesis and codes for methionine when present at a site other than the start site. The initiation codon is often preceded by an untranslated sequence, also called leader sequence. The ribosome moves along the mRNA in 5' to 3' direction in a GTP dependent manner to facilitate elongation of the polypeptide chain.
Answer: Base pairs are formed when adenine forms a hydrogen bond with thymine, or cytosine forms a hydrogen bond with guanine. The second part of a nucleotide is the phosphate, which differentiates the nucleotide molecule from a nucleoside molecule.
Explanation:
Answer:
Golgi receives a vesicle containing newly synthesized proteins that were sent by the endoplasmatic reticulum. Then it modifies the proteins and sends them where they need to go.
Explanation:
Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, which is the primary structure for protein synthesis. They read the mRNA code and add the correct amino acid using transference RNA to build the protein. The synthesizing protein is driven to the rough endoplasmic reticulum and translocated to the lumen. Once there, the protein suffers a few modifications, one of them is folding to become functional. Once membrane proteins are folded in the interior of the endoplasmic reticulum, they are <u>packaged into vesicles</u> and <u>sent to the Golgi complex</u>, where it occurs the <em>final association of carbohydrates with proteins</em>. The Golgi complex <u>sends proteins to their different destinies</u>. Proteins destined to a certain place are packaged all together in the same vesicle and sent to the target organ. In the case of membrane proteins, they are packaged in vesicles and sent to the cell membrane where they get incrusted.
Nearly flat. Rhinos don't really reproduce rapidly.
