Since the initial acceptance of cell theory, recent advances in biotechnology have provided scientists with far more information

about the structure and function of cells. How has the discovery of DNA and our current understanding of the cell cycle affected cell theory.

Answer:

The cell theory was given by the scientists Scheldien and  Schwann that explains that all organisms are made of cell. Cells performs the structural and functional unit of life. The complex and simple organisms are made of cell. The new cells arise arise from the pre existing cells.

The cell modify its structure according to the function it perform. The cell cycle process increases the cell numbers in the organisms. The advancement in biotechnology and molecular bio is helpful to prove that DNA is the genetic material of all the living organism that are passed from the parents to the next generation.

Answer:

Cell theory is originally presented by Schleiden and Schwann and initially, it has only two points and after some time the third point added but with the discoveries in the field of biotechnology there are many other points that are accepted and known as the modern cell theory.

According to the cell theory, all organisms are made up of one of the multiple cells and arise from the pre-existing cells by the cell division. A cell is a basic unit of structure and function.

Other than these three there are several other points are drive with the help of discoveries regarding discoveries which is helping to form that DNA is the hereditary material that passes all necessary information to the next generation.

FILL IN BLANK !!!Question 10 options:
Mamont248 [21]

Answer:

DNA contains genes that can be read to create <u>messenger RNA</u>  that directs the <u>ribosome</u> to build certain <u>proteins</u> as needed by specific cells or situations.

Explanation:

DNA is a nucleic acid that contains in its structure a specific sequence of nucleotides, whose quantity and order determine the genetic information of an individual. A chromosome consists of a DNA molecule, and each fragment of this molecule constitutes genes with specific instructions for determining structural and functional characteristics.

Transcription is the process by which DNA can be read and transcribed into messenger RNA (mRNA), a molecule that carries the genetic code to the ribosomes for protein synthesis, in a process called translation.

<em>When a </em><u><em>cell needs to synthesize a specific protein, transcription and translation mechanisms occur so that the protein can be synthesized</em></u><em>.</em>

A cell is placed into a solution and is left sitting for 24 hours. When you come back you notice the cell is exactly the same si
kotegsom [21]

Answer:

Isotonic Solution

Explanation:

There are commonly three types of solutions:

  • Hypertonic solution = the concentration of solute is greater than in the cell
  • Hypotonic solution = the concentration of solute is less than in the cell
  • Isotonic solution= the concentration of solution and cell is same.

So, if the cell was in any other solution, it would have been burst or it would shrink. but nothing changed because it was in a solution where outside environment is similar to the internal environment

Proteins – what they are and how they're made. Proteins are the key working molecules and building blocks in all cells. They are produced in a similar two-step process in all organisms – DNA is first transcribed into RNA, then RNA is translated into protein.

The function of transverse tubules is to a. rapidly move action potentials to the interior of the muscle fiber. b. conduct ATP m
aleksley [76]

Answer: Option A.

Transverse tubules rapidly move the action potential to the interior of the muscle potential.

Explanation:

Transverse tubules are cylindrical pockets found in the plasma membrane of muscle cells. They are formed from phospholipid bilayer or sarcolemma of skeletal or cardiac muscle cells. They have membrane that have large concentration of ion channels,transporters and pump. They permit action potention into the cell and also to a particular structure sarcuplasmic reticulum. They play a role in regulating cellular calcium concentration.
