Answer:
The sequence of bases in a DNA molecule can determine the order of amino acids in a protein molecule. Groups of three bases called triplets represent different amino acids. This is the basis of the genetic code . A sequence of bases (genetic information) on DNA that codes for a protein is called a gene .
Explanation:
Solution:
Plant and animal cells both undergo in mitotic cell divisions. The main difference is that how they can form the daughter cells during cytokinesis. During that stage, animal cells form furrow or cleavage that gives way to formation of daughter cells. While, during telophase, plant cells phragmoplast forms in the center of the cell.
Animal cells have centriols that helps the organization of mitotic spindle and completion of centrioles. But plant cell don’t have centrioles.
Animal cells divide at anywhere and all the time while the plant cell is divide only in specialized region known as the meristems.
Answer:
C the number of daughter nuclei is half the number of parent nuclei.
The theme "form=function" represents the shape of the biomolecule that determines its function.
The theme "form=function" can be best understood by the study of proteins. Proteins are the biopolymer made up of the repeting subunits of monomers called the amino acids. Amino acids are the organic compounds made up of an amino group and a carboxyl group. In addition to this, they contain a functional "R-group" that determines the amino acid. These R-groups in the amino acids of a protein either attract or repel from each other giving a three dimensional structure to the protein which is critically important for its functioning.
Similarly, the cell wall of the plants are made up of the cellulose. It is a structural carbohydrate biomolecule responsible for providing rigidity to the cells and protecting them.
Answer:
Mutations in the HBB gene cause sickle cell disease. The HBB gene provides instructions for making one part of hemoglobin. Hemoglobin consists of four protein subunits, typically, two subunits called alpha-globin and two subunits called beta-globin.
