4 0

Answer:

In 1953, Watson and Crick determined the double-helix composition of DNA, that is, the molecule comprising human genes. They found that the composition of DNA was a spiral of two strands of DNA or a double-helix polymer, each comprising a lengthened monomer chain, that is, the nucleotides wrapped around each other.  

The DNA, that is, a nucleic acid formed of nucleotides combined into chains or long strands with the help of covalent bonds. The nitrogenous bases present in the DNA are guanine, adenine, thymine, and cytosine.

Changes in the amount of sea ice can disrupt normal ocean circulation, thereby leading to changes in global climate. Even a small increase in temperature can lead to greater warming over time, making the polar regions the most sensitive areas to climate change on Earth
