Approximately what percentage of the human genome actually codes for proteins?
34kurt

The correct answer is: 2.5%

The vast majority of the human genome (97.5%) is comprised of non-coding DNA with different functions. Non-coding DNA includes telomeres, introns, non-coding RNA genes and gene regulatory sequences.

• Telomeres-ends of DNA with protective role (prevents shortening of DNA),

• Non-coding RNA genes-e.g. genes for tRNA,

• Gene regulatory sequences such as promoter, enhancers and silencers.

How do you calculate the velocity of the boat relative to the shore
Dvinal [7]

Answer:

Relative velocity simply means velocity relative to a certain observe point, in this case, the river shore.

This is a type of complex movement; a boat is moving with a certain velocity, let's say 8 m/s. However, the river this boat moves on also has its velocity, let's say 2 m/s. Since the shore isn't moving, the velocity of the boat relative to the shore will be simple resultant velocity of the boat's and the river's velocities.

Let's illustrate this with two examples:

1) if the boat is moving downstream both are moving in the same direction, so the resultant will be 8 m/s + 2 m/s = 10 m/s.

So, any spectator looking at the boat from the shore will think its velocity is 10 m/s, when in reality it's 8 m/s.

2) if the boat is moving upstream, these two velocities have opposite directions, so the resultant will be 8 - 2 = 6 m/s

So, as a short summary, relative speed is an object's speed in regard to another chosen referent point.
