In the process of protein synthesis, the messenger RNA (m-RNA) is responsible for carrying the genetic code transcribed from DNA to specialized sites within the cell (called ribosomes) where the information is translated into protein composition. The sequence of amino acids in a particular protein is determined by the sequence of t-RNA, c-DNA or r-RNA do not decide the amino acid sequence in protein synthesis.
Antiparallel strands of a DNA molecule means that
one strand turns anti-clockwise
the phosphate groups of two DNA strands, at their ends, share the same position
the phosphate groups at thestart of two DNA strands are in opposite position (pole)
the phosphate groups at thestart of two DNA strands are in opposite position (pole)
