Open the combination lock using the old combination. Remove the u-bar from the lock body so it's in the Unlock position. Use a screwdriver to open the anti-dust cover on the back of the combination lock. Align the old combination numbers to the guide points.
A base pair (bp) is a unit consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix, and contribute to the folded structure of both DNA and RNA.
The base-pairs â¦ are actually specific sequences of nucleotides (i.e. adenine, thymine, guanine and cytosine, labelled A, T, G, and C respectively) which encode genes. In other words, the DNA in each organism is made of these bases, but their sequences differ from organism to organism.NA strands may be very similar (a human DNA strand is 99% alike an ape DNA strand!!), but due to recombination and probability, there isn't any DNA strand like other one. Co â¦ nsider 4 DNA strands, each with the same nucleotide sequence. Now recombine two of them in any point, any VARIABLE point.
