Answer: TRUE
Explanation:
The cell division that takes place during the growth and development of an organism is in an as MITOSIS. Mitosis takes place in somatic cells that is, body cells that are not involved in the production of gametes. The difference stages of mitosis were originally defined by cellular features observable through a LIGHT MICROSCOPE. These stages includes:
--> PROPHASE: when viewed under a light microscope, each chromosome shortens and thickens and is seen to consist of two chromatids. The Centriole begin to separate.
--> METAPHASE: The nuclear membrane disappears, a spindle forms, the chromosomes line up across the middle of the cell and become attached to the spindle fibres at their centromeres.
--> ANAPHASE: The sister chromatids are pulled apart to opposite ends of cell as the spindle fibres contract.
--> TELOPHASE: A nuclear membrane forms around each set of chromatids, and the cell divides into two daughter cells.
Answer:
DNA.
Explanation:
Type II restriction endonucleases always cleave at or near their recognition sites. They produce small, well-defined fragments of DNA that help to characterize genes and genomes and that produce recombinant DNAs.
Answer:
<em>The correct option is C) OH</em>
Explanation:
In the field of chemistry, radicals can be described as atoms, molecules or ions which have at least one unpaired electron.
The formation of a radical occurs when a single covalent bond breaks so that each of the atoms that had been involved in the formation of the covalent bond can have an unpaired electron. Examples of radicals include OH, NH4+ etc.
Other option, like option B, is not true because a molecule of water does not have any unpaired electrons in its valence shell.
Answer:
They create models of genes, proteins, and traits. In sexual reproduction, each parent randomly passes on one of its two copies of each gene to its offspring. ... Each offspring can inherit a different combination of gene versions, so siblings can have different traits from each other and from their parents.
