Answer: The secondary structure of protein is creates by hydrogen bonds between the hydrogen atoms on the amine group and the oxygen atom on the carboxyl group.
Explanation:
Secondary structure of protein is a three dimensional type of protein that is formed by hydrogen bonds between the hydrogen atoms on the amino group and oxygen atom on the carboxyl group. The secondary structure of protein chains are organised into two regular structures which are alpha helixes and beta pleated sheets. In alpha helix the chain is like a loosely coiled spring and beta pleated sheets, the chains are folded. Meanwhile, protein have three types of structures which are primary, secondary and Tertiary.
There are two cell divisions in meiosis ( Meiosis 1 and Meiosis 2). It has the same thing as mitosis but it happens twice.
Answer:
A. The formation of species
Explanation:
Answer:
Mitosis
Explanation:
Mitosis is not a source of genetic mutation because it take place mostly in the somatic cells. This is because it does not lead to the production of gametes . In mitosis, the parent cells divide into two daughter cells and each daughter cells are genetically identical to the parent cell because they carry the same number of chromosomes as the parent cell. There is no genetic variation in this.
