nignag [31]

Answer:

Cytosine nucleotides

Explanation:

In most organisms, the methylation of DNA exists in three different sequence motifs. These include: CG (or CpG), CHG or CHH (H represent A, T or C). In plants, cytosine can be methylated at CpG, CpHpG, and CpHpH regions (H represents any of these nucleotide A, T or C except guanine. DNA methylation is almost majorly found in CpG dinucleotides, with the cytosines on both strands usually always being methylated in mammals.

During which of the following phases of the cell cycle is the nuclear envelope present? Choose all that apply.
cupoosta [38]

Answer:

-S-phase

-Late telophase

Explanation:

The cell cycle is divided into two main phases: interphase and mitotic phase.

Interphase is phase characterized by the the cell growth and DNA copy (replication). During this phase, the cell prepares for division (mitotic phase).

Mitotic phase is subdivided into four phases: prophase, metaphase, anaphase and telophase. At the end of prophase, nuclear envelope breaks down and condensed chromosome (DNA structures) are released.

During the late telophase, nuclear envelope is reformed.

You are assigned to process blood and have one tube that needs to be centrifuged. what is your course of action?
aliina [53]

course of action is obtain a tube of water filled to the same volume to place across from the specimen

<h3>Why do blood samples need to be centrifuged?</h3>

The effect of heparinized blood sample centrifugation time on clinical chemistry and immunology results has rarely been studied. The WHO recommended a 15-minute centrifugation time without citing any scientific publications. The time spent centrifuging has a significant impact on the turnaround time.

On a Roche Cobas 6000 system, we examined 74 parameters in samples from 44 patients to see if there was a statistically significant difference in test results between specimens centrifuged at 2180 g for 15 minutes, 2180 g for 10 minutes, or 1870 g for 7 minutes. For each centrifugation condition, two tubes with different plasma separators (both Greiner Bio-One) were used. Deming fit was used to make statistical comparisons.
