DNA is a chain of nucleotides bonded together. On that chain there are particular portions of it that the sequence of the nucleotide codes for particular proteins; this is known as a gene. In eukaryotric cells, DNA is coiled around proteins such as histones to form chromatids which when two join at the centre by a centromere to form a chromosome.
The correct answer is it always occurs in a predictable pattern.
Ecological successsion is defined as a <em>change in the structure of species of an ecological community over a period of tim</em>e. The succession that begins in a new environment by uninfluence of pre-existing species is called primary succession. The disruption of pre-existing community because of succession is called secondary succession. Ecological succession happens in a predictable pattern. The ecological communities undergoes predictable change which creates a disturbance or initial formation of new habitat. This changes occurs in an orderly manner and can be best explained by the example of trees how they grow bigger and bigger.
A genes dna is transferred to a molecule called an rna in the cell nucleus. Then the Rna assembles the protein and continues until the ribosomes "stop".
The answers would be vacuole
