I think the fact that should be included in the lesson plan is that the symptoms of ODD usually appear no later than early adolescence. A child diagnosed with ODD presents with a pattern of negativity, disobedience, and hostile behavior toward authority figures. This pattern of behavior occurs more frequently than is typically observed in individuals of comparable age and developmental level.
Answer:
The correct answer is "short RNA primers; Okazaki fragments".
Explanation:
The missing information of this question is as follows:
"Replication of the lagging strand of dna is accomplished by repeatedly making __________ followed by 1,000-2,000 nucleotide segments called __________"
The correct answer is "short RNA primers; Okazaki fragments".
DNA replication always occurs from 5' to the 3' end, in what is known as the directionality or the end-to-end chemical orientation in molecular biology. This fact makes difficult the synthesis of the lagging strand of DNA. In order to achieve this short RNA primers are bound to segments of DNA (serving as the 5' end available for the DNA polymerase to synthesize), which leads to the discontinuous synthesis of Okazaki fragments that are later linked together by the enzyme DNA ligase.
Answer:
When the virus infects a cell, the RNA genome enters the cell and programs it to make new virus particles. These virus particles are released from the cell and go on to infect new cells. In humans, poliovirus is ingested, and replicates in cells of the gastrointestinal tract.Poliovirus, the prototypical picornavirus and causative agent of poliomyelitis, is a nonenveloped virus with a single-stranded RNA genome of positive polarity. The virion consists of an icosahedral protein shell, composed of four capsid proteins (VP1, VP2, VP3, and VP4), which encapsidates the RNA genome (1).RNA viruses generally have very high mutation rates compared to DNA viruses, because viral RNA polymerases lack the proofreading ability of DNA polymerases. The genetic diversity of RNA viruses is one reason why it is difficult to make effective vaccines against them.
