Replication starts at the ORIGIN OF REPLICATION.
In prokaryotes which has close double stranded DNA molecule, replication usually starts from a single origin of replication and it proceeds around the circle bidirectionally, that is, in both directions. The process of replication in prokaryotes is very rapid and it produces only a few errors.<span />

100 POINTS!!! ANSWER ASAP [5 SENTENCE ANSWER] Explain the relationship among distance, mass and gravitational force between any
Karolina [17]
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled. If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on.

Hope this helps.

You are a scientist who discovers three new species of beetles in the jungles of South America. Describe, in detail, how a prote
Elenna [48]
Since all of the three beetle species posses the protein, we can use it to determine their relations. We can study the sequence of the amino acids that make the protein and the 3D structure of the protein. The more differences there are in amino acid sequences and the structure of the protein, the species are more distantly related because they have diverged a long time ago and their genes that produce that protein have undergone many changes over time.

Match each definition to the appropriate term. locus
liraira [26]
I) Locus- the chromosomal site where a specific gene is located. A locus is a fixed position on a chromosome, like the position of a gene or a marker. Each chromosome carries ,many genes; human's estimated haploid (n) protein coding genes are about 20,000, on the 23 different chromosomes.


ii) Interference; the observed double crossover frequency differs from the expected double crossover frequency. Cross over interference is used to refer to the non-random placement of crossovers with respect to each other during meiosis. It results in widely spaced crossovers along chromosomes. Interference may exert its effect across whole chromosomes. As chromosomes in many eukaryotes are large, interference must be able to act over megabase lengths of DNA. 

iii) Linkage- the tendency for genes located in close proximity on the same chromosome to be inherited together. Normally when two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.

iv) Recombination- the process by which a new pattern of alleles on a chromosome is generated. Genetic recombination is the production of offspring with combinations f traits that differ from those found in either parent. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information transfer between the chromosomes.

19. Speed humps and speed tables are effective speed reduction measures because ___________ A. they allow traffic to proceed at
charle [14.2K]
The correct answer is "they allow traffic to proceed at the speed limit".

First of all, letter B is incorrect as the main function of the speed humps is not to bring harm to the motorists but to ensure the safety of the flow of the traffic. Letter A is correct as speed humps makes the motorists slow down on purpose for the traffic to proceed at a certain speed limit.
