The femur is the longest bone which is present in our thigh and also call as thigh bone. The division of femur can be divided into shaft, proximal and distal. In some aspect it is the strongest bone of our body and it helps in any activities.
Answer:
RNA synthesis proceed in 5' to 3' direction.
Explanation:
The process of formation of RNA molecule from the DNA template is known as transcription. The transcription process is necessary for the gene expression.
The process of RNA synthesis always occur in the 5' to 3' direction. The RNA polymerase moves from the 3' strand and adds the polynucleotide and RNA synthesis in 5' to 3' direction. The anti parallel nature of the nucleotide causes the RNA synthesis in 5' to 3' direction.
Answer:
Tectonic Plates and Plate Boundaries
There are three main types of plate boundaries:
Convergent boundaries: where two plates are colliding.
Divergent boundaries – where two plates are moving apart.
Transform boundaries – where plates slide passed each other.
Symbiosis is a close relationship between two species in which at least one species benefits. For the other species, the relationship may be positive, negative, or neutral. There are three basic types of symbiosis: mutualism, commensalism, and parasitism.
Mutualism
Mutualism is a symbiotic relationship in which both species benefit. An example of mutualism involves goby fish and shrimp
