The genetic code was originally deciphered, in part, by experiments in which synthetic polynucleotides with repeating sequences

were used as mRNAs to direct protein synthesis in cell-free extracts. Under these conditions, ribosomes could be made to start translation anywhere within the RNA molecules, with no start codon necessary. What peptide would be made by translation from a synthetic mRNA made of the repeating dinucleotide CGCG…?

Answer:

Translation is the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins. The process starts where the mRNAs (messenger RNA) copies the DNA and sends this message to the ribosome. In the ribosome for each triplet of nucleotide an amino acid is bond to the growing chain of amino acid that will eventually form a protein.

You can look up for the translation for the genetic on the internet. Which tells you which triplet codifies for an specific amino acid.

If the code reads. CGC GCG CGC GCG etc.

The result would be an a peptide/protein containing alternating arginines and alanines, because CGC codifies for Arginine and GCG codifies for alanine.

What feature distinguishes this type of capillary from a continuous capillary?
Vitek1552 [10]
<h2>Blood Vessels</h2>

Explanation:

  • Fenestrated capillaries are "leakier" than ceaseless vessels.
  • They contain little pores, notwithstanding little holes between cells, in their dividers that take into consideration the trading of bigger particles.
  • This sort of narrow is found in territories that require a great deal of trade between your blood and tissues.  

Function-

  1. <em>Capillaries are exceptionally minor veins so little that a solitary red platelet can scarcely fit through them. </em>
  2. They help to interface your courses and veins in addition to facilitating the trading of specific components between your blood and tissues.  
  3. <em>This is the reason tissues that are extremely dynamic, for example, your muscles, liver, and kidneys, have a wealth of vessels.</em>
  4. Less metabolically dynamic tissues, for example, specific sorts of connective tissue.

Explain why it makes sense that the levels of estrogen and progesterone are low in the blood of a female during menstruation
lawyer [7]
Hey there,

Your question states: Explain why it makes sense that the levels of estrogen and progesterone are low in the blood of a female during menstruation.I'm a guy, but I just happen know this information.The reason why the levels of estrogen and progesterone are low in the blood of a female during menstruation is to basically produce (FSH) or  follicle stimulating hormone. We need to remember that menstruation is part of the menstrual cycle, which to would help a women/teen to handle/establish a well and healthy pregnancy, (if that makes sense). The average cycle would basically be i think about like 25-28 days. And one thing to remember is that when there is a <span>ripening egg,this causes estrogen levels to rise. This would be the reason why its low.

Hope this helps</span>
