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.
The options that are incorrect are A) representation of a complete set of a cell's polypeptides, B) the complete set of an organism's polypeptides, C) the complete set of a species' polypeptides, and D) karyotype, which makes E) the complete set of an organism's genes the correct answer to what defines a genome.
Answer:
Osteochondral Progenitor cells
Explanation:
Osteochondral Progenitor cells are cells that can form a specific type of tissue. These cells form cells that can give rise to the bone and its components, especially fibers. These Progenitor cells originate from the mesenchymal stem cells.
The cells which form the bone are known as the osteoblasts and the cell which forms the fiber is known as the chondroblasts.
Thus, Osteochondral Progenitor cells is correct.
Answer: its CO2 for the first one
