What organelle does the mRNA strand go to so protein synthesis can start?
sergiy2304 [10]

Answer:

The mRNA strands go to the cytoplasm to meet ribosomes so protein synthesis can start.

Explanation:

In protein synthesis, the first step is to <em>synthesize messenger RNA</em>, mRNA. The coping process of the DNA section for the desired protein is called <u><em>transcription</em></u>, and it happens in the <em>nucleus</em>. After that, it occurs <em><u>translation</u></em>, when the formed <em>mRNA moves to the </em><em>cytoplasm</em> through the nucleus membrane pores. Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, the primary structure for protein synthesis. Ribosomes are made of <em>protein and ribosomal RNA</em> and can be found in the r<em>ough endoplasmic reticulum</em> or floating in the <em>cytosol</em>. They read the mRNA code and add the correct amino acid using <em>transference RNA</em> to build the protein. mARN has a <em>start and end codon</em> that tells where to start and stop adding amino acids. When the ribosome reaches the end codon, it means that protein synthesis is finished. The new 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 <em>folding</em> to become functional. Finally, protein is transported by vesicles to the Golgi complex, and from there to its final destiny.

Which of the following statements BEST describes chromosomes?
Blizzard [7]
<span>The answer is c. Chromosomes carry the codes for hereditary traits. Chromosomes are thread-like structures made of proteins and DNA. Codes for hereditary traits are present in a molecule of DNA. Chromosomes can be found in the nucleus of each cell. Humans have 46 chromosomes in each cell (not 460) arranged in 23 pairs (not 230). Hope this helps. Let me know if you need additional help!</span>
