Answer:
Explanation:
A tRNA with the complementary anticodon is attracted to the ribosome and binds to this codon. The tRNA carries the next amino acid in the polypeptide chain. The first tRNA transfers its amino acid to the amino acid on the newly arrived tRNA, and a chemical bond is made between the two amino acids
Answer: B. beta
Explanation:
Sickle cell anemia is a inherited disorder which occur due to mutation of gene responsible for synthesis of hemoglobin protein. Typically the gene which is responsible for synthesis of beta-globin protein which make the beta chains in the hemoglobin is affected by the mutation. As a result of this the red blood cells acquire a shape of sickle rather than round. Pain, cold, stress, dehydration and illness are the symptoms associated with this disorder.
Answer;
3. the two organisms belong to the same kingdom
Explanation;
-The classification of living things includes 7 levels, from the highest to lowest rank: kingdom, phylum, classes, order, families, genus, and species . The most basic classification of living things is kingdoms.
-The broadest classifications are by domain and kingdom; the most specific classification is by genus and species.
Therefore; if two organisms are in the same phylum, then it means they both belong to the same kingdom, because kingdom is the rank of classification higher than phylum.
During mitosis, the <em />nuclear membrane breaks down and the duplicated chromosomes are separated and evenly distributed to opposite sides of the cell. Cytokinesis involves the division of the cytoplasm and the organelles that are contained within.
This describes the process of cell division. All of these events happen in the M phase of mitosis. The breaking down and fragmentation of the nuclear membrane to expose the genetic material is in the prophase. The next phase is the metaphase when the duplicated chromosomes align in a straight line (metaphase plate). Anaphase involves the separation of chromatids and by the time the chromatids reach the opposite side then the cell enters telophase. Lastly, cytokinesis involves restoration of the nuclear membrane, division of the cytoplasm, and production of two daughter cells.
