The rate of mRNA deadenylation varies inversely with the frequency of translation initiation for an mRNA:  the higher the frequency of initiation, the slower the rate of deadenylation.

Tropical Deciduous Forest  Temperatures are hot year-round, averaging 25–39ºC. Rainfall is substantial, at around 130–280 cm per year, but the dry season is distinct, often 2–3 months or longer. 

Closer to the Tropics of Cancer and Capricorn Much of India consists of tropical deciduous forest, containing teak trees. Because of the distinct dry season, many of the trees in tropical deciduous forests shed their leaves.

phyA is rapidly degraded following its activation by light. Thus, protein degradation, in addition to phosphorylation, is emerging as a ubiquitous mechanism regulating many cellular processes, including light and hormone signaling, circadian rhythms, and flowering time.

Heterochromatic regions, which tend to be rich with adenine and thymine (AT-rich) DNA and relatively gene-poor, stain more darkly in G-banding.

In contrast, less condensed chromatin (Euchromatin)—which tends to be rich with guanine and cytosine (GC-rich) and more transcriptionally active—incorporates less Giemsa stain, and these regions appear as light bands in G-banding.

Genetic exchange also happens between distantly related organisms by horizontal gene transfer, or HGT.

HGT is particularly important to prokarytotes and is the most common way by which they acquire new genes.
