Answer:

False. There are 20 amino acids, but 64 possible codons.

Explanation:

Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. The total number of possible codons is 64, from which 61 codify amino acids -more than one codon codify for the same amino acid-. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.

The codons indicating the initiation or stop points during the translation process are:

• The start codon AUG is the most common sequence used by eukaryotic cells and places near the 5´extreme of the molecule. However, other codons might be used as well. Prokaryote cells might use the codons GUG or UUG.

• The end codons are UAA, UAG, UGA.

Why are common names not a good reference to a species?
Rufina [12.5K]

Answer:

All the above options are correct. Hence the most relevant answers for the questions are all the options mentioned above.

Explanation:

Common names are not preferred because they can vary according to the people living in the society, religion, culture and their own suitability. We can get various example where a animal is known by various names in different countries or region.

Providing scientific name that is accepted by all over the world is more convenient rather than common names which are given by the local people to the specific animal or bird. Scientific name remove all the confusion between the the people. common names can be kept according to their location culture species and their language

If you go a bit overboard and feel a sudden pinch and you start bleeding, It means that something penetrate in your skin and torn off your blood vessel so that you start bleeding.

May be there was any pin or sharp needle thing was there in board that pinch into your skin and your epidermis could not resist that and it is no longer intact and you created a wound on your skin.

Epidermis the surface epithelium of the skin of an animal, overlying the dermis. and in this case it is wounded by that pin.
