Phosphorous is required to synthesize the deoxyribonucleoside triphosphates used in DNA replication. A geneticist grows some E.

coli in a medium containing nonradioactive phosphorous for many generations. A sample of the bacteria is then transferred to a medium that contains a radioactive isotope of phosphorus (^32P). Samples of the bacteria are removed immediately after the transfer and after one and two rounds of replication. Assume that newly synthesized DNA contains ^32P and the original DNA contains nonradioactive phosphorous. What will be the distribution of radioactivity in the DNA of the bacteria in each sample? Immediately after the transfer After one round of replication After two rounds of replication If the gene for primase were mutated so that no functional primase was produced, what would be the effect on the two types of bacterial DNA replication? Theta replication Rolling circle replication

Either through conventional nucleoside triphosphorylation or through aqueous production of 2′-deoxyribonucleoside triphosphates (dNTPs).

<h3>Deoxyribonucleotides are produced in what ways?</h3>

A purine or pyrimidine base is joined to deoxyribose, which is then joined to a phosphate group, to form deoxyribonucleotides. By reducing ribonucleoside diphosphates, they are created.

<h3 /><h3>How does radioactive DNA become made?</h3>

Sanger started synthesising new DNA strands from single-strand templates with the enzyme DNA polymerase while incorporating radioactive nucleotides into the new DNA. A primer that can bind to a recognised area of the template strand is necessary for DNA polymerase. Early success was constrained by the absence of appropriate primers.

After telophase I of meiosis, the chromosomal makeup of each daughter cell is a. tetraploid, and the chromosomes are each compos
murzikaleks [220]

Answer:

The correct answer will be option-B.

Explanation:

Meiosis is a type of cell division which proceeds in two stages: meiosis I and meiosis II and result in the formation of four daughter cells.

The meiosis I is known as the reductional division as two daughter cells are formed with reduced ploidy level that is haploid cells from diploid cells.  The cells formed contains chromosomes with two chromatids as the DNA amount gets doubled after the DNA synthesis.

Thus, Option-B is the correct answer.

Air masses move from areas with high pressure (such as the poles of the Earth) to areas with low pressure (the equator). The tem
valina [46]

Answer:

B

Explanation:

Warm because land gains heat faster than water when heated by the sun. The heated land then transfers the heat to the atmosphere. The air mass is dry becasue a continent is mainly land and very little water (unlike oceans). There is, therefore, very little moisture in the continental tropical air mass.

What does a thick layer of an ice core tell us? A thin layer?
Elena L [17]
Through analysis of ice cores, scientists learn about glacial-interglacial cycles, changing atmospheric carbon dioxide levels, and climate stability over the last 10,000 years. Many ice cores have been drilled in Antarctica.
