The isobars are defined as the lines that represents the equal atmospheric pressure. Each line represents a certain value. These lines never intersect one another. The presence of these lines in an atmospheric map enables the reader to identify and understand the regions of high and low atmospheric pressure. The values of these isobars are written in terms of millibar. Isobars that are closer to one another indicates a changing pressure at a faster rate over distance and the wind speed is relatively high. Whereas, when isobars are widely spaced, it depicts a pressure change at a slow rate with respect to distance and the wind speed is low.
In the case of the amino acid leucine alone, there are six different codons (TTA, TTG, CTT, CTC, CTA, and CTG) that can recognize and translate tRNA. Since there is only one codon to be translated, only one tRNA is required.
The anti-codon in the tRNA identifies complementary positions on the codon, and due to the characteristic of the third-base motif, there is no 1: 1 ratio between the number of codons present and the required anti-codon.
