The basic sequence of a nucleic acid makes it possible to determine, applied to the gene, the amino acid sequence of the polypeptide concerned. It is by hydrogen bonds between the pair of nitrogenous bases that two strands of the DNA or RNA helix are linked.
They are called bases because they can be protonated at the nitrogen atoms and react weakly in aqueous solution. In nucleic acids, they are generally N-glycosidically linked to ribose or deoxyribose. Structurally active base pairs in the double-stranded DNA may be formed via hydrogen bonds between nucleic bases. The nucleobase sequence in an RNA or DNA strand is also called a base sequence.
Answer:
523.035 km
Explanation:
It is given that, a distance of 325 miles is covered on a trip to Europe. In this problem, we need to find how many kilometers will you be traveling.
To convert 325 miles to km, we must know the conversion from miles to kilometers.
1 mile = 1.60934 km
For 325 miles, multiply it by 1.60934 i.e.
325 miles = (325 × 1.60934) km
= 523.035 km
Hence, you will be travelling 523.035 km on a trip to Europe.
