Answer:
In their Mitochondria.
Explanation:
Organisms contain cells. Each cell has organelles (which are the organs of the cells). There is an organelle called mitochondria which is known as the powerhouse of the cell as it create the neccessry ATP energy.
Answer:
The correct answer is C
Explanation:
In asexual reproduction method, the offspring generated is identical genetically to the parents. But this is not the case in sexual reproduction. The reason being that the gametes or sex cells produced has only one set of chromosomes and are therefore haploid after the process of meiosis. Meiosis is the process when the offspring formed has chromosomes from two parents and is not identical to the parent. Only certain characteristics are inherited by the offspring from both the parents and offspring has different set of characteristics.
There is a process of assortment taking place inside the cell when the double set of chromosomes becomes one set in a gamete. Out of the pair of chromosomes, there is a random selection. Due to this random assortment, there is a genetic variation between the gametes as the gene alleles on the chromosome are not the same. This principle is said to be the Mendel’s first law of segregation.
Another process of combining chromosomes is the crossing over during the meiosis stage which results in variety of chromosomes. We can say that recombination is possible.
Hence, we can note that during assortment and crossing over, there is no chance for two offspring to be identical to the same mother or father with the exception of identical twins. In the case of identical twins, the genetically identical characteristics develops from same fertilized egg.
From the above process, the structure of gene gets changed creating a variant that can get transmitted to next generation. The change is caused by altering the single base units of DNA or rearranging larger section of genes.
Proteins are unbranched polymers constructed from 22 standard α-amino acids.
The protein show four levels of structural organisation; the primary structure, secondary structure, tertiary structure and quaternary structure.
The structure of proteins are stabilized by peptide bonds between the amino acid and hydrogen bond between the peptide chainds.
The primary structure of a protein is determined by the sequence of amino acids, but secondary and tertiary structures of protein define their natural or native conformation.
The solubility of protein varies according to the pH, ionic strength, nature of solvent, temperature etc.
Proteins can be classified as simple proteins or conjugated proteins on the basis of their composition.
The proteins can also be classified as fibrous proteins or globular proteins on the basis of their shape.
Proteins play a major part in body structure and function as most of the molecules like antibodies, immunoglobulins, hemoglobin, myoglobin ,most of the enzymes are proteins.
So proteins are also called building blocks of the body.
