Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.
The three steps that are required for DNA replication are initiation, elongation and termination.
What is DNA replication ?The process in which DNA of a cell under go duplication to produce two copies during S-phase of cell cycle called as DNA replication.
It involves 3 steps such as initiation step where the origin of replication of DNA molecule undergo unwinding into two DNA strands.
An incomplete unzipping by forming replication fork is created is catalyzed by the helicase enzyme.
Secondly in elongation step the DNA polymerase enzymes make the complementary sequence against each parent template strand.
It is an unidirectional, one strand which is synthesized in a continuous manner called leading strand, the strand which is synthesized in a discontinuous manner called lagging strand with Okazaki fragments.
Termination occurs in the last step, when the parent molecule has been completely replicated.

Question 4 of 10
Newton's second law of motion states that the acceleration of an object
depends on the force exerted on it, divided by its mass. This law can be
summarized by the equation F = mx a.
Why is this a law and not a theory?
A. Newton's statement involves mathematics. A theory is a
description based on observations,
OB. Newton's statement describes the relationship between mass,
acceleration, and force. A law is an explanation of natural events.
O C. Newton's statement is supported by research. A theory is only an
educated guess
D. Newton's statement has been proved with scientific evidence. A
theory can change when new evidence is found that does not
support the theory

The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.

In the general population, 1 in 300 individuals is a carrier for Tay-Sachs disease, while 1 in 30 individuals of Ashkenazi Jew descent are carriers. Tay-Sachs also affects 1 in 30 individuals with French-Canadian ancestry, although two completely unique mutations are responsible for the Ashkenazi and French-Canadian mutations.
A) What are the chances of two individuals having a child with Tay-Sachs if both individuals are not of Ashkenazi or Franch-Canadian descent?
B) What are the chances of two Individuals having a ¢hild with Tay-Sachs lf one Individual Is of Ashkenazi descent and one ls not?
In the general population where 1 in 300 individuals is a carrier for Tay-Sachs disease, while 1 in 30 individuals of Ashkenazi Jew descent are carriers. Tay-Sachs also affects 1 in 30 individuals with French-Canadian ancestry then in this condition , 1 in 2 will get the disease that is there is 50% possibility.
What type of disease is discussed in the question ?It is an autosomal recessive disorder.
The chances where the two two individuals having a child with Tay-Sachs if both individuals are not of Ashkenazi or Franch-Canadian descent is 25 % that is the child will not have any disease.
The chance where the child inherits a mutated one from one parent and becomes a carrier, but will not have the condition themselves. 1 in 4 (25%) chance that means the child inherits a faulty gene from both parents and develops Tay-Sachs disease.

Astronomy (from Greek: ἀστρονομία, literally meaning the science that studies the laws of the stars) is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole.[1]
Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowadays, professional astronomy is often said to be the same as astrophysics.[2]
Professional astronomy is split into observational and theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects. This data is then analyzed using basic principles of physics. Theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena. These two fields complement each other. Theoretical astronomy seeks to explain observational results and observations are used to confirm theoretical results.
Astronomy is one of the few sciences in which amateurs play an active role. This is especially true for the discovery and observation of transient events. Amateur astronomers have helped with many important discoveries, such as finding new comets.

Answer:
Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.

Which muscle extends the knee, laterally rotates the tibia, aids in abduction and medial rotation of the femur, and tautens the iliotibial tract to brace the knee when the opposite foot is lifted
The popiletus muscle is the muscle that extends the knee , laterally rotates the tibia.
The popliteus muscle is a little muscle that extends the knee and form muscle the floor of the popliteal fossa. It is part of deep posterior leg muscles, that rotate laterally tibialis posterior, flexor digitorum longus and flexor hallucis longus.
The popliteus muscle extends to the knee joint. It is formed from the femur and the posterior horn of the lateral meniscus, and also extend to the proximal tibia.
The popliteus muscle help to function in an gait cycle by causing the flexion of the extended (“locked”) knee.
Therefore, The popiletus muscle is the muscle that extends the knee , laterally rotates the tibia.

regulation of the cell cycle is dependent on cyclins and cyclin-dependent kinases. the key that allows a cell to progress beyond the restriction point is
The key that allows a cell to progress beyond the restriction point is the phosphorylation of specific proteins (for example RB) by Cdk. The cyclin-dependent kinases (CDKs) are able to phosphorylate different substrates.
Cyclins regulate the progression of the cell cycle by their interaction with cyclin-dependent kinases (Cdks).
This binding activates the Cdks, thereby converting them into functional enzymes that phosphorylate target proteins and thus regulate cell cycle progression by bypassing restriction points of the cell cycle.
CDKs can phosphorylate different substrates by transferring phosphate groups from adenosine triphosphate (ATP) to specific amino acidic residues in these substrates.
For example, CDKs phosphorylate Rb proteins and thus regulate their activity during the cell cycle.
