Mendel observed phenotypic traits during the cross of pea plants. Subsequently, he noted each trait had only two forms.

<h3>Mendel's Experiments</h3>

Mendel crossed pure-breeding pea plants, and then he crossed hybrid generations, as well crossed the hybrid progeny back to parental lines.

From these crosses, Mendel observed the descendence and then formulated a series of inheritance principles.

Mendel noted traits can be divided into dominant and recessive phenotypic characteristics.

Dominant characteristics were inherited in an unaltered manner after hybridization of true breeding [plants.

How are bacteria classified

mrs_skeptik [129]

Bacteria are classified into 5 groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters.

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).
