Researchers performed an experiment to investigate DNA replication. First, they synthesized radioactively-labeled nucleotides, w
Andrej [43]

Answer:

DNA replication is a semiconservative process.

Explanation:

The DNA molecule is made of two chains (or two strands), also called double-stranded (two chains).

There is complementarity of nucleotides or nitrogen bases:

- Thymine with Adenine,

- Guanine with Cytosine.

This DNA molecule is duplicated. For this, locally, we have an opening of these two chains by enzymes. We speak of enzymatic complex. This set of enzymes comes to open both strands of DNA. After opening the two strands, in the nucleus, there are several free nucleotides which bind to the template strand by complementarity.

We had a single molecule of DNA, we then had two. The two chromatids (or the two DNA helices) are therefore sister, because they are strictly identical. We speak of a semi-conservative replication because we keep one of the two matrix strands to copy identically its complementary, thanks to the complementarity of nucleotides or nitrogenous bases.

slava [35]

Seeds perform various functions for the plants that generate them, among them the essential function is dispersal to a new location, nourishment of the embryo, and dormancy at the time of inappropriate conditions.  

Seed coat is the part of the seed that protects the seed from temperature-associated, physical, or water destruction, it helps in the protection of developing embryo, and it is the seed coat, which makes sure that the plant seed remains in a dormant state until the circumstances become ideal for the plant embryo to sprout or germinate.

A cell undergoing cell division identifies a chromosomal misalignment. How does this normally affect the progress of the cell cy
telo118 [61]

When a cell undergoing cellular division identifies that a chromosome misalignment had taken place the cell cycle stops until the error it's corrected.

Option two of the question states that the cell cycle will <u>proceed uncontrollably, this is not the case for the error at hand</u>. Although this can be a problem for cells and leads to the appearance of cancer, it is not caused by chromosome misalignment. As is the case with options 3 and 4.

The stop or delay in the <u>cell cycle is what normally takes place in these situations.</u> This stoppage is done by the <em><u>spindle checkpoint</u></em>, which prevents <u>duplicate chromosomes from separating.</u>

During this time, the error it's corrected. If a cell is not able to correct the error at this time, many situations can follow. <u>However, the most likely is that the cell will undergo a <em>programmed cellular death.</em> </u>
