Match the steps in the cell cycle in the correct order

Biology
1 answer:
Tcecarenko [31]1 year ago
6 0

Answer:

1. Chromosomes line up - metaphase

2. Cell growth - G1

3. Final preparations for division - G2

4. Chromosomes get pulled apart - anaphase

5. DNA replication - S

6. Chromosomes condense - prophase

7. Chromosomes uncoil and nucleus reforms - telophase

8. The cytoplasm and organelles divide, and now there are two identical cells - cytokinesis

Explanation:

There are four primary phases, or stages, in the cell cycle, which is a systematic process. Each stage has a goal that has to be achieved before moving on to the next. G1, S, G2, and mitosis are the stages.
There is growth during the G1 phase. A lot of protein is produced and water is pumped in, increasing the volume of the cell. The DNA is also examined at this time to see whether there has been any damage. The G1 phase precedes the S phase, therefore before going into S phase, the cell must make sure it has enough energy reserves.

The cell duplicates its DNA during the synthesis phase, also known as the S phase. DNA content doubles due to the duplication of all chromosomes. The compact state of DNA is created by proteins, which do not exist in and of themselves. Therefore, in order to ensure that the new DNA is properly packed when DNA is replicated, new packaging proteins must be produced. Histones are the proteins that house DNA. The production of new DNA is closely linked to the production of new histones.

A cell multiplies its organelles during the G2 phase. Right before the cells divide into two distinct cells during mitosis, the G2 phase occurs. There must be distinct functioning organelles in each daughter cell. Organelles like the golgi and endoplasmic reticulum are linked networks of sizable membrane pouches that may change size. Other organelles, including mitochondria and chloroplasts, are separate structures that must separate similarly to how cells do.

The process of physically dividing a cell into two daughter cells is called mitosis. Prophase, metaphase, anaphase, and telophase are its four basic stages. The nuclear membrane deteriorates as the chromosomes thicken during prophase. The center of the cell's chromosomes align during metaphase. One chromosome splits in half during anaphase, sending one half to either side. The telophase is characterized by the pinching together of the cell's centre to form two separate cells.

Transcription chain elongation is thought to generate ____ supercoils ahead of the transcription bubble and _____ supercoils beh
frosja888 [35]

Answer:

a. positive; negative

Explanation:

Transcription is the process of forming an RNA molecule from a DNA template molecule. In this process, the strands of DNA separate and one serves as a template for RNA, while the other is inactive. At the end of the transcript, the tapes that have been split back together again.

The transcription process is divided into three steps: initiation, stretching and termination

During the stretching phase, transcription chain elongation occurs. In this phase the enzyme called RNA polymerase starts to move through the DNA molecule, unwinding its helix and producing an increasingly lengthened RNA molecule. The already transcribed DNA is rewound almost immediately, recomposing its double helix. This process is called the elongation phase.

During this process, it is believed that positive supercoils  are generated ahead of the transcription bubble and  and the negative supercoils behind it.

What color do you think an object would be if it reflected all colors of the visible spectrum?
tankabanditka [31]
C. The object would be white. White is like the mother of colors,  and besides, black wouldn't let you see anything. Blue and yellow are NOT relevant.

<span>The nurse should tell the patient that eating a variety of healthy food is the best source of vitamins<span>. This is should be told by the nurse in a nice and emphatic manner, especially in this case wherein patients diagnosed with HIV are particularly emotionally sensitive. While this is true, the nurse should not advise the patient to stop taking his or her supplements; especially being diagnosed with HIV, his or her immune system is very frail and needs more than the usual nutrients compared to the normal population. </span></span>
