Answer:

The correct answer will be-

   1. DNA is found in the nucleus of a cell

    2. Organisms store and transmit genetic information

    3. Cells contain protein molecules.

Explanation:

The study of DNA started much before the discoveries of Rosalind Franklin and Maurice Wilkins.

Nucleus of cell was discovered by Robert Brown in 1831 but the material present inside the nucleus called "nuclein" (DNA) came from the studies of Johann Friedrich Miescher in 1869.

Proteins as a constituent of cell were discovered by the experimental analysis of Gerhardus Johannes Mulder in 1837.

DNA as a genetic material came from the experimental studies of Frederick Griffith in 1928, Oswald Avery, Maclyn McCarty, and Colin MacLeod in 1944, and Hershey and Chase in 1952.

Franklin and Maurice Wilkins are known for their work on the the structure of DNA as they were able to produce high-resolution X-ray photographs of DNA fibres called Photo 51 in 1952 using X-ray diffraction technique. By 1953 Franklin concluded concluded that DNA shows helical structure with phosphates on outer side.

Thus, 1. DNA is found in the nucleus of a cell

         2. Organisms store and transmit genetic information

         3. Cells contain protein molecules.

             are the correct options.

if you found piophila casei and bone eating beetles on a body, what could you say about the time of death
IRINA_888 [86]
Well, both tend to feed on already decaying things, so I'd say that the body is at least 20 to 50 days after death. Beetles normally take over around that time because maggots can no longer get through the dry tissue.

lesya [120]

Answer:

The correct answer is - option D. intramembranous ossification

Explanation:

Conversion of mesenchymal tissue into bone directly is known as intramembranous ossification. The bone formation is the process that involves the conversion of mesenchyme or primitive connective tissue from laying of bone directly. It is made up of granular cells and fibers in the matrix.

It is the formation of tissue of bone in a fetal without any template or cartilage base during fetal development.

Thus, the correct answer is - option D. intramembranous ossification
