QUESTION ID:2

Amid consistent rise in deaths of pedestrians and cyclists, Punjab has taken the lead among the states and UTs to implement the ‘right to walk’ by making it mandatory for all road owning agencies, including the NHAI, to provide foot path and cycle tracks in all future expansion of roads and construction of new ones, reports Dipak Dash.

The state government has issued these directions following two court orders after PILs were filed at Punjab and Haryana HC and another in the Supreme Court.

As per a communication from Punjab chief secretary Vijay Kumar Janjua to Punjab government’s traffic adviser, Navdeep Asija, “in future all expansions of existing roads and construction of new roads, a mandatory provision of cycle tracks and footpaths should be made by all road owning departments and agencies”.

The letter sent last week added that all agencies such as the public works department, local bodies, NHAI and urban development departments have been instructed to prepare an action plan to construct footpaths and cycle tracks with a time frame and budget provision.

TIMES VIEW: The right to walk is a cool idea. Pedestrian walkways and cycle tracks must be built everywhere. However, we must also audit the existing tracks and examine their lacunae. For instance, such tracks are regularly invaded by motorbikes. That apart, pedestrian-only tracks often have huge gaps, which makes walking a dangerous exercise. In other words, the right to walk must be converted into a proper mission with every angle taken care of to make it a success.

One of the lacunae associated with existing tracks, cycle tracks is:

Based on the context given below, answer the following questions:

DNA in eukaryotes is a double-helical structure with two anti-parallel strands intertwined equidistantly. The double-helical structure was deciphered by James Watson and Francis Crick on the basis of X-ray diffraction studies. The hydrophilic backbones of alternating sugar and phosphate groups are on the outside of the helix held together by phosphodiester bonds. The purine and pyrimidine bases of both the strands are stacked inside the double helix. Adenine binds with thymine with hydrogen bond and cytosine binds with guanine with hydrogen bond. The DNA is transcribed into messenger RNA, ribosomal RNA and transfer RNA. Messenger RNA is translated into protein in the cytoplasm.
