[mÌ¥ÉÌÅ]) are an ethnic group from the mountainous regions of China, Vietnam, Laos, and Thailand. Hmong are also one of the sub-groups of the Miao ethnicity (èæ) in southern China. Hmong groups began a gradual southward migration in the 18th century due to political unrest and to find more arable land.
In this way a DNA molecule is similar in structure to a ladder in which the sugar and phosphate groups make the uprights and the nitrogen base groups the rungs. There are four types of nitrogen bases or base groups. 1  Adenine (A). 2  Thyamine (T).3  Cytosine (C). 4  Guanine (G).he nucleotides in the DNA molecule are linked in series from one phosphate, to the next sugar, to the next phosphate and so on. The DNA molecule can be considered as a ladder with the phosphate and the sugar molecules making up the uprights and the bases making up the rungs.
Confidence votes 33. DNA (or deoxyribonucleic acid) are very small bits of protein within the nucleus of a cell that fit together to create specific genetic patterns. This formation looks like a ladder (two vertical strands on each side and short, horizontal cross pieces in the center), but is twisted into a spiral.he four different bases are Cytosine, Guanine, Thymine, and Adenine. Cytosine links with Guanine, and Thymine links with Adenine to form the ladder. The ladder part is made up of genes. These DNA strands make up chromosomes, x-shaped things that are located in the nucleus of eukaryotic cells.
