Initiation:
In the cytoplasm, protein synthesis is actually initiated by the AUG codon on mRNA. The AUG codon signals both the interaction of the ribosome with m-RNA and also the tRNA with the anticodons (UAC). The tRNA which initiates the protein synthesis has N-formyl-methionine attached. The formyl group is really formic acid converted to an amide using the -NH2 group on methionine (left most graphic)
The next step is for a second tRNA to approach the mRNA (codon - CCG). This is the code for proline. The anticodon of the proline tRNA which reads this is GGC. The final process is to start growing peptide chain by having amine of proline to bond to the carboxyl acid group of methinone (met) in order to elongate the peptide.
Sounds like a trick question.
Maybe not. contamination is easy, but gloves are a barrier between other organic material on yourself (such as what you ate for lunch) and what you are testing.
Other than the fact your DNA will be different than another person’s DNA, if we assume you are theoretically free of debris of any kind, then your DNA would test the same always.
Note: any contamination after purifying extract for a small sequence can give false positives. There are repeat sequences possible that would interfere if you are testing a small enough sequence.
I hope that helps!
The answer is C. RNA, but it should really by called mRNA for Messenger RNA
It is the circular pathway of water on the earth from the atmosphere, to the surface, to the ground, and back.
Respiration is the way that plants release water into the atmosphere.
Human placental lactogen( hPL) hormone released during fetal development is primarily responsible for preparing breasts for lactation.
- Human placental lactogen also stimulates milk ,known as human chorionic somatomammotropin. It's made by the placenta. It gives nutrition to the fetus. secretion of milk is called lactation
- Mother milk contains all the nutrients that an child needs in the first 6 months of life, including fat, carbohydrates, proteins, vitamins, minerals and water. It's fluently digested and efficiently used. secretion of milk is called lactation. bone milk also contains bioactive factors that compound the child's immature vulnerable system, furnishing protection against infection, and other factors that help digestion and immersion of nutrients. mother milk also protect the child from disease.
