Answer:
c. Major groove
Explanation:
The interaction surfaces of proteins are, in general, varied. From the point of view of the secondary structure, the surfaces of the proteins are formed by the surfaces of their α helices, β sheets and loops that conform them. The surfaces of the DNA molecules are less varied: the B-DNA helix has a monotonous “screw” shaped surface with phosphoribose ridges between which two grooves (major and minor) are formed. The difference between different nucleotide sequences can only be seen from outside in the major groove, where the bases appear. The surfaces of RNA molecules that possess tertiary structure (such as t-RNA) are almost as complex as that of proteins.
Since the major groove is the only site where the bases are accessible from outside the B-DNA without distorting it, the major groove constitutes the main recognition site. As the interaction between molecules is stronger if their surfaces are complementary, the protein-DNA interaction usually occurs by filling the major groove.
Answer:amount of carbon-14 and nitrogen-14 in the remains
Explanation:This is called radiocarbon dating. It is used for once-living things between 100 and 50,000 years old.
The number of chromosomes in the daughter cells will be the same as the original cell. This is because during mitosis, the chromosomes are replicated and then divided equally into the two daughter cells.
The daughter cells produced by mitosis have the same number of chromosomes as the parent cell. This is because during mitosis, the cell duplicates its chromosomes, and each daughter cell inherits one copy of each chromosome from the parent cell. The number of chromosomes in the daughter cells will be the same as the original cell. This is because during mitosis, the chromosomes are replicated and then divided equally into the two daughter cells.
The process of mitosis begins with the replication of the cell's chromosomes. This results in each chromosome being duplicated. The cell then divides into two cells, each with the same number of chromosomes. Mitosis is important for the maintenance of the cell's genetic integrity. Without mitosis, the cell would be unable to duplicate its chromosomes and would eventually die.
Mitosis is a vital process in the life of a cell. It allows the cell to duplicate its chromosomes and to divide into two cells, each with the same number of chromosomes. This is important for the maintenance of the cell's genetic integrity.
