What initiates translation?

a) trna brings the first amino acid to the protein chain

b) a ribosome detaches from the mrna strand

c) a ribosome reads a start codon

d) mrna leaves the nucleus for the cytoplasm

c) a ribosome reads a start codon

Explanation:

Translation is a process in which a protein is synthesized messenger RNA in (mRNA). The process of translation occurs in ribosomes which mainly synthesize proteins. The ribosomes composed of many mRNA molecules and proteins.The ribosome translate mRNA molecule in three stages namely initiation,elongation and termination. During initiation ribosomal subunits binds to the start of the mRNA sequence.The a molecule of tRNA carries amino acid methionine which to the start codon of the mRNA sequence During elongation ribosomes continuously translate each codon.Amino acid added to a chain by means of a peptide bond.Termination occurs when a ribosome reaches a stop codon,

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.
