Answer options:

  • extraction and observation of DNA
  • identification of ribose and deoxyribose
  • recognition of RNA as DNA’s messenger
  • construction of an accurate DNA model

Answer:

  • identification of ribose and deoxyribose

Explanation:

Phoebus Levene was an American biochemist who studied the structure of DNA and RNA. He was able to isolate the sugars (ribose and deoxyribose) from the nucleic acids, which are an important part of their structure.

He also determined how the nucleic acid components combine to form the nucleotides, the basic building blocks of nucleic acids, and how the nucleotides combine in chains to form the polymer.

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.
