It's true, it's in the book
Velocity is a vector and its magnitude depends on the direction. If it is positive in one direction, going in the opposite direction it is negative. But speed is a scalar and does not depend on the direction. It has the same value, whatever the direction. That is how the absolute value of velocity is speed.
There is almost never an "IF". All non-zero vectors have a constant, specified direction. Only a zero-vector has a direction which is unspecified.
Vertical is a relative term. It usually refers to a direction pointing in the opposite direction of Gravity. So if you are in outer space, then I guess there is no real "vertical" direction.
Unfortunately there is no consistent direction: it depends on the context. If dealing with bearings (eg navigation) North is 000 degrees and the angle is measured in the clockwise direction starting from the Northward direction. In the context of coordinate geometry, particularly if working with polar coordinates, angles are measured in the anti-clockwise direction, starting with the x-axis (pointing East) as 0 degrees. Generally speaking, though, angles may be measured in any direction.
vectors help in determining the direction . they give the magnitude of the number as well as the direction of the quantity
Chromosomes are located within the nucleus of a eukaryotic cell. They are made up of DNA and proteins and contain the genetic information of the cell. During cell division, chromosomes condense and are visible under a microscope.
In eukaryotic cells chromosomes are found within the nucleus. The only exception to this is during mitosis (i.e. cell division) when the nuclear membrane disappears and the chromosomes line up at the metaphase plate and then move towards opposite direction in anaphase. Reaching the telophase these are again surrounded by the nuclear envelop.
In DNA replication, the direction of transcription is from 3' to 5' prime.
in a direction opposite to that of the replication fork
In a living organism, DNA replication occurs in the 5' to 3' direction.
During DNA replication, the direction of synthesis is from the 5' to 3' end of the new strand.
Yes, DNA replication occurs in the 5' to 3' direction on the template strand.
DNA polymerase adds nucleotides in the 5' to 3' direction during DNA replication.
DNA polymerase exclusively travels in the 5' to 3' direction during the process of DNA replication.
During DNA replication, DNA polymerase moves along the template strand in the 3' to 5' direction.
so that they can be replicated into sister chromatids and then split apart in anaphase
Yes, DNA polymerase can only add nucleotides in the 5' to 3' direction during DNA replication.
