Answer:

Hutton's Unconformity

At Siccar Point, during the lower Silurian Llandovery epoch around 435 million years ago, thin beds of fine-grained mudstone were laid down gradually deep in the Iapetus Ocean, alternating with thicker layers of hard greywacke formed when torrents swept unsorted sandstone down the continental slope. Siccar Point is a rocky promontory in the county of Berwickshire on the east coast of Scotland. It is famous in the history of geology for Hutton's Unconformity found in 1788, which James Hutton regarded as conclusive proof of his uniformitarian theory of geological development.

What was known before Franklin and Wilkins conducted their studies of DNA? Check all that apply. DNA is found in the nucleus of
kvasek [131]

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.

You have a plant with yellow seeds, which express a dominant phenotype. How would you determine the plant's genotype? Conduct a
Archy [21]
The answer is <span>Conduct a test cross with a purebred recessive plant. 

</span>

Test cross is the cross between an organism with unknown dominant genotype and an organism with known recessive genotype.

<span>Since dominant trait results from a dominant allele, the test cross can determine if an unknown genotype is heterozygous and homozygous dominant. </span>

If A is dominant allele, and a is recessive allele, then AA is dominant homozygote, Aa is a heterozygote, and aa is recessive homozygote.

<span>According to the Punnett square, if all of the offspring are heterozygote (Aa), then unknown genotype is dominant homozygous (AA). If half of the offspring are the heterozygote, and the other half are recessive homozygote, then the unknown genotype is heterozygote (Aa).</span>
