The appropriate sequence of steps involved in recombinant DNA technology are as under :-
1) Selected gene is isolated.
2) Restriction enzymes cut DNA into fragments.
3) Fragments of DNA are inserted into a vector.
4) Vector and recombinant DNA multiply.
5) Recombinant DNA is inserted into host.
In the very first step, the desired gene/genetic material for cloning is isolated from the cell. To do this the cell is lysed. Cells can be lysed by sonication or using chemicals like detergents.
In the second step, isolated DNA/gene is cut with the help pf biological scalpels known as restriction enzymes. The vector (usually it is a plasmid) is also cut down using restriction enzymes.
In the third step, the fragment of the restriction digested DNA (gene) and the vector are ligated together.
In the fourth step, this vector in which desired gene has been incorporated is cloned to generate various copies.
In the last step, this recombinant DNA is inserted into a host cell where is expressed i.e. in host cell this desired gene produces its product (protein).
Most likely I believe that the growth of that same species in two different habitats will vary and have more of a bigger growth rate in the pond that gives more nutrients in the species undergoing photosynthesis so therefor I conclude that the algae will grow in a faster rate with the habitat that provides more sun.
Answer:
In response to shortened day length and cool temperatures, many trees begin a period of senescence where the breakdown of chlorophyll exceeds chlorophyll production. The leaves of these trees appear to change to yellow and in orange.
Answer:
The correct answer is: As ventricular systole start, the AV valves are closed and the semilunar valves are closed. Because the ventricles are contracting and both valves are closed, pressure increases rapidly leading to ejection.
Explanation:
The heart functions like a bomb that pumps blood to every part of the body, which is fundamental for the proper function of every organ.
The cardiac cycle has two main phases: the diastole and the systole. During the diastole, blood returns from the body through the vena cava and is deposited in the right atrium of the heart. When the pressure in the right atrium becomes bigger than the pressure in the right ventricle, the tricuspid valve opens and the blood flows to the left atrium.
During systole, the atria suffer a depolarization that makes the atria's muscle contract. Thanks to this, the blood goes through the atria to the ventricles.
During isovolumetric contraction, the ventricles contract but the pulmonary and aortic valves remain closed. When the ventricular muscle contracts, the semilunar valves open.
Sthe stages of meiosis are:
Prophase I
Metaphase I
Anaphase I
Telophase I
