Answer:

Dragon fruit, a kind of fruit belonging to Hylocereus spp., has brought about interest in China not only due to its important economic value with high contents of nutrients, but also due to the striking tolerance to drought stress. Fifteen morphological traits and 111 Inter-Simple Sequence Repeat (ISSR) markers generated from 16 primers were firstly employed to discriminate 50 accessions recently selected in China, as well as to evaluate their genetic relatedness. According to univariate statistical analysis of morphological traits, high variations were observed between or/and within the wild and cultivated lines. The dendrogram of 50 accessions was constructed based on morphological traits. Taking 7.50 as a threshold, three major clusters could be observed, i.e. the first included nine genotypes, which mainly belonged to wild accessions; the second clusters standing for the red pulp genotypes; the third consisting of the white pulp accessions. Each ISSR primer generated 4–10 obvious DNA bands ranging from 100 bp to 1500 bp, with the average of 6.9 per primer.

E. coli cells grown on 15N medium are transferred to 14N medium and allowed to grow for two more generations (two rounds of DNA
White raven [17]

Answer:

Option (d).

Explanation:

DNA is the genetic material of all the organism except some viruses. DNA is composed of nitrogenous base, deoxyribose pentose sugar and the phosphate group.

DNA replicatese by semi-conservative mode of replication in which one the daughter DNA consists of one newly synthesized strand and one parental strand. This mode of replication was explained by Messelson and Sthal experiment. The cells from 15N medium are transferred to 14N medium the band of intermediate density was observed. The daughter DNA consists of one 15N DNA strand and one 14N DNA strnd. This strand undergo replication in the 14N medium. This time one low density DNA band ( contains 14N - 14N DNA strand) and one intermediate density band ( 14N-15N DNA).

Thus, the correct answer is option (d).
