Answer:DNA is shown to be the genetic material in bacteria and some phages.
DNA is shown to be present in mitochondria, chloroplasts and nucleus, where genetic function is performed
Specific genes can be isolated and spliced into bacterial DNA, which can be inserted into a bacterial cell, and then its genetic expression is monitored.
DNA and RNA are found to be the only macromolecules in eukaryotes that consist of a set of subunits which can combine in unique sequence
Explanation:
1. Lipds is another macro molecule with different subnits of fatty acids and glycerol,therefore the option ( DNA is found to be the only macro molecule in Eukaryotas that has different sub units) is WRONG.
2 The correlation of action and absorption spectra varies with different organisms DNA. e..g in viral cells there is a wide difference between the absorption and action spectra, that is no correlation, while some bacterial cells showed correlations. The option(For DNA, content in various cell types action and absorption spectra of ultraviolet light are correlated IS WRONG.
prophase
Further genetic variation comes from crossing over, which may occur during prophase I of meiosis. In prophase I of meiosis, the replicated homologous pair of chromosomes comes together in the process called synapsis, and sections of the chromosomes are exchanged.
Hope it helps!
The steatite seals found in the Indus valley resemble seals found at contemporary sites in Mesopotamia.
The steatite seals are also referred to as the Pashupati seals and are found in major regions of the Indus Valley civilization.
Scientists have managed to find a variety of seals that belongs to the Harappan site of the Indis Valley civilization.
These seals have also been known to be founded in the Mesopotamia region. Scientists are researching and finding evidence that the steatite seals found in the Indus valley and Mesopotamia may belong to the same ancestors and might have migrated over time.
