What are the major steps in completing gel electrophoresis?

Physics
1 answer:
nadezda [96]3 years ago
4 0
The major steps in completing gel electrophoresis start with permeable gel with holes on a single side. Different DNA is placed in each hole via pipette. The gel then gets an electric current sent through it to positively charge the opposite side. This should create bands in the gel that can be seen under UV light. These are then used to compare similarities in genes to find relationships.

A 82-kg fisherman in a 112-kg boat throws a package of mass m = 15 kg horizontally toward the right with a speed of vi = 4.8 m/s
abruzzese [7]

Answer:

0.37 m/s to the left

Explanation:

Momentum is conserved.  Initial momentum = final momentum.

m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂

Initially, both the fisherman/boat and the package are at rest.

0 = m₁ v₁ + m₂ v₂

Plugging in values and solving:

0 = (82 kg + 112 kg) v + (15 kg) (4.8 m/s)

v = -0.37 m/s

The boat's velocity is 0.37 m/s to the left.

Object A attracts object B with a gravitational force of 5 newtons from a given distance. If the distance between the two object
givi [52]

Answer:

Four times higher

Explanation:

F- G (m1 x m2)/ r^2

if r 1  = 2 and r 2 = 1       therefore  F = G (m1 x m2)/  1^2 is 4 times higher than

                                    2^2 since G and m1  and  m2 remained the same

What type of energy is released when a firecracker explodes
Ludmilka [50]

-- Sound energy.  That's how you hear it explode.

-- Light energy.  That's how you see it in the sky.

-- Heat energy.  That's why you get burned if sparks fall on you.

-- Potential energy, as all the pieces fall to the ground.

These were all stored in it as chemical energy before it exploded.
