Another characteristic that you want to include in the introduction is bacterial reproduction. Prokaryotic cells have only one c
hromosome and lack any organelles such as a nucleus, which limits the requirement for numerous cellular processes when a cell divides to form two daughter cells In both major forms of bacterial reproduction, binary fission and snapping, the single chromosome must replicate so that each daughter cell will carry a complete chromosome During binary fission, the cell replicates its DNA and each DNA molecule is attached to the cytoplasmic membrane. The growing cell elongates the cytoplasmic membrane, which separates the daughter DNA chromosomes. The formation of a cross wall allows for invagination of the cytoplasmic membrane The cross wall completely divides daughter cells, which may or may not separate. Snapping division seen m some Gram-positive bacilli, occurs when only the inner portion of a cell wall is deposited across the dividing cell This now cross wall puts tension on the outer layer of the old ceil wall. Eventually, the outer wall breaks at its weakest point with n snapping movement that tears it most of the way around. The daughter cells can then remain hanging together almost side by side being held by a small remnant of the original outer wall. Choose from the following statements the ones that correctly discuss reproduction using binary fission in a bacterial cell Select all that apply. A. Each daughter cell will contain an equal number of organelles.
B. The daughter cell will be a permanently smaller copy of the mother ceil but will contain a complete genome
C. Each daughter cell is an exact copy of the other, both genetically and morphologically
D. Due to the stretching of the cytoplasmic membrane, both cells will contain a complete genome
C. Each daughter cell is an exact copy of the other, both genetically and morphologically
.
D. Due to the stretching of the cytoplasmic membrane, both cells will contain a complete genome
Explanation:
Binary fission can be described as a method of asexual reproduction in which a parent cell replicates and splits into two new daughter cells. As a result of binary fission, the daughter cells formed are exactly similar to the parent cell. It is one of the most common methods by which a bacterial cell divides.
Other options like the option B are false because the daughter cells will not be permanently smaller than the parent cell. They will grow in size.
When you stain a cell that reacts with an enzyme that is found in the lysosome, you would expect to see the dye in the endoplasmic reticulum. Cell staining is the name of this test. It is used to visualize the cell much better in a microscope. There are certain stains to be used depending on the need.
Helicase molecules is active first in DNA replication. DNA helicase are enzymes capable of unwinding duplex DNA to provide the single- stranded DNA templates that are required in processes such as replication and recombination.all helicase separates the strands double mix helix using energy derived from hydrolysis nucleotide.
The cell membrane is a selectively permeable membrane which controls what goes in and out to ensure that not just anything comes in through it's own accord.
