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.

How does a prokaryotic cell such as bacteria differ from eukaryotic cells?​
LenKa [72]

Answer:

The main difference is that EUKARYOTIC cells <em><u>have</u></em> a nucleus while a PROKARYOTIC cell <em><u>does not</u></em>. Instead, prokaryotes have free floating genetic material.

Explanation:

To help you remember this distinction:

EU = YES eukaryotes <em><u>HAVE</u></em> a nucleus.

PRO = NO prokaryotes <em><u>DO NOT</u></em> have a nucleus.

I hope this helps and good luck with your assignment.

Punnet squares are a useful tool for predicting what the offspring will look like when mating plants or animals. Reginald Crundall Punnett, a mathematician, came up with these in 1905, long after Mendel's experiments. Let's take a look at how Punnet squares work using the yellow and green peas example from im not sure about the tree by three thing but maybe this will help :)
