A DNA molecule consists of two strands of nucleotides twisted together to form a double helix. The sugar-phosphate backbone is found on the outside of this helix and the bases are found braching towards the middle. Hydrogen bonds join the thenitrogenous bases and hold the two strands together.
Therefore your answer is sugar and phosphate.
<span>Simple.
All of the millions of different life forms (the diversity of life) have come about by natural selection, whereby random mutations in the genes have either succeeded or failed.
But all life can be traced back to a common single-celled origin. Thus we have the unity of life where we (possibly) share more than 50 % of our DNA with a crocodile.eg:analogous organs, homologous organs.</span>
Answer:
more flexibility in movement
Explanation:
it allows the worm to pass waves of movement along its body to move through loose earth.
<h2>Production of mitochondrion DNA </h2>
Explanation:
- The cell is not capable to complete reaction related to ATP production and electron transport.
- This is because the electron transport chain and ATP production are combined with the association of protein in the inner membrane of mitochondrion DNA.
- Mitochondria are the powerhouses of the cell. In all eukaryotes that don't rely upon photosynthesis, the mitochondria are the primary wellspring of adenosine triphosphate (ATP), the vitality rich intensify that drives central cell capacities.
- These capacities incorporate power age (for instance, in muscle compression and cell division), the biosynthesis, collapsing and debasement of proteins, and the generation and control of membrane possibilities.
The question is incorrect. The correct question is as follows:
The prosthetic group of hemoglobin and myoglobin is _______?
The organic ring component of heme is _______?
Under normal conditions, the central atom of heme is ________?
In ________ the central iron atom is displaced 0.4 A out of the plane of the porphyrin ring system.
The central iron atom has _______ bonds: ________ to nitrogen atoms in the porphyrin, one to a _______ residue and one to oxygen.
Answer:
The hemoglobin is an important protein that transport oxygen in the body and contains the pigment that gives the red color to the red blood cells. The myoglobin protein is responsible for transport of oxygen in muscles.
The heme molecule acts as prosthetic group for both myoglobin and hemoglobin. The porphyrin ring is present in heme molecule. The iron molecule especially Fe2+ is present in heme molecule. The deoxyhemoglbin states occur when the central atom is displaced 0.4 Å. The iron central atom can form six bonds and forms four bonds with the prophyrin of nitrogen and one bond with histidine molecule. Histidine acts as a buffer fir the blood.
