How is the absolute value of velocity speed?
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.
If a vector has constant direction then?
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.
What way is vertical?
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.
Which direction do you measure an angle?
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.
Applications of vectors?
vectors help in determining the direction . they give the magnitude of the number as well as the direction of the quantity
Where is the chromosome located within the eukaryote cell?
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.
Where are chromosomes found in eukaryotic cell?
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.
Where does replication of the two DNA strands takes place?
in a direction opposite to that of the replication fork
During mitosis why do the chromosomes condense before they start moving around the cell?
so that they can be replicated into sister chromatids and then split apart in anaphase
In what direction does a DNA molecule split during replication?
A DNA molecule splits in the 5' to 3' direction during replication. Each strand acts as a template for the synthesis of a new complementary strand.
The difference between deletion duplication inversion and translocation?
Deletion is the loss of a segment of DNA, duplication is the replication of a DNA segment, inversion is the flipping of a DNA segment, and translocation is the movement of a DNA segment to a new location in the genome. These are all types of structural variations that can lead to genetic disorders or diversity in populations.
What is the name of the strand that replicates in a direction toward the replication fork?
Lagging strand.
The direction of DNA replication on the leading strand occurs in the?
The direction of DNA replication on the leading strand occurs in the 5' to 3' direction. DNA polymerase synthesizes the new strand continuously in this direction since it can add nucleotides to the 3' end of the growing strand.
DNA replication takes place when?
DNA replication takes place when preceding interphase.
Why do chromosomes assort independently?
Chromosomes assort independently during meiosis due to the random alignment of homologous chromosomes at the metaphase plate. This random alignment results in different combinations of alleles being passed down to offspring, increasing genetic diversity.
What type of mutation results in the Reversal of the direction of part of the chromosome?
The type of mutation that results in the reversal of the direction of part of the chromosome is called an inversion mutation. It occurs when a segment of the chromosome breaks and is reinserted in the opposite orientation. This can disrupt the normal functioning of genes located within the inverted region.
Why does DNA replication have to be in an anti-parallel direction?
DNA replication occurs in an anti-parallel direction because the DNA helix is composed of two strands running in opposite directions. This ensures that the new DNA strand is synthesized in a continuous manner without interruptions. The anti-parallel arrangement allows for the complementary base pairing that is necessary for accurate replication.
