Answer:
<h2>All chromatids have one newly synthesized strand that contains BrdU and one parental strand that contains thymidine.</h2>
Explanation:
DNA replication occurs by semi-conservative way, in which one strand is newly synthesized and one is old, as both the strands of parental DNA serve as template and and finally two copies are formed from a single DNA molecule.
As each strand serve as a template, so that it makes complementary strand of itself by base pairing, as G pairs with C and A pairs with T.
So in newly formed DNA, one strand is parental and one strand is newly formed.
Hence, in the presence of bromodeoxyuridine (BrdU), after one round of replication, all chromatids have one newly synthesized strand that contains BrdU and one parental strand that contains thymidine.
The presence of a homologous structure suggests common ancestry, and further suggests that the nearest common ancestor of two organisms had the trait which is homologous. Comparison of several modern organisms with different variations of the same homologous structure can suggest what the original ancestor's actual characteristics were, and comparison of the structure in different organisms can also suggest which organisms are more or less closely related
The use of the isotope 32P as a tracer element in the study of invasion and lysis of bacteria by viruses has shown that bacteriophage protein enters the bacteria.
Phosphorus-32 is a radioactive isotope of phosphorus, such that the nucleus of phosphorous-32 contains 15 protons and 17 neutrons, one more neutron than the most common isotope of phosphorous, phosphorous-31.
Answer:
Time in space is measured using the speed of light.
Explanation:
Oxygen and glucose are the products of photosynthesis. Oxygen is used by plant for respiration or it gets dissipated in the air. Glucose is stored for feeding the plant. It is also stored in the form of starch
