Question: Please use the following information to answer the question(s) below.  A group of six students has taken samples of their own cheek cells, purified the DNA, and used a restriction enzyme known to cut at zero, one, or two sites in a particular gene of interest.

Analysis of the data obtained shows that two students each have two fragments, two students each have three fragments, and two students each have one only. What does this demonstrate?

Answer:

"The two students who have two fragments have one restriction site in this region."

Explanation:

A restriction enzyme, restriction endonuclease, or restrictase is an enzyme that cuts DNA into trashes at or close precise appreciation sites inside particles identified as restriction locations. Restriction enzymes are one session of the wider endonuclease collection of enzymes. In the laboratory, restriction enzymes (or restriction endonucleases) are used to cut DNA into minor trashes. The scratches are constantly made at exact nucleotide arrangements. Unlike restriction enzymes recognise and cut diverse DNA sequences.

Asi todas las células son muy pequeñas. ¿Qué limitaciones físicas y metabólicas determinan el tamaño celular? ¿ A qué problemas
N76 [4]

Answer:

- Limitación física: la relación superficie volumen es baja para un intercambio eficiente de sustancias con el medio

- Limitación metabólica: en principio no existen limitaciones metabólicas  

Explanation:

La membrana celular es una estructura fundamental para el funcionamiento celular, ya que de la membrana celular depende el intercambio de nutrientes y desechos por parte de la célula con su entorno (medio extracelular). En células muy grandes la relación entre la superficie cubierta por la membrana y el volumen celular es muy baja, lo cual dificulta el intercambio de compuestos (tanto nutrientes como desechos) con el medio extracelular. Por otro lado, los mecanismos metabólicos en principio no deberían verse afectados por el tamaño celular. Por ejemplo, los perfiles metabólicos de expresión génica son independientes del tamaño celular y están adaptados a diferentes tipos celulares, desde una célula huevo que es proporcionalmente varias veces más grande que un célula diferenciada la cual sin embargo no ha perdido la capacidad de dividirse, un ejemplo de esto son las células cancerosas derivadas de células epidérmicas diferenciadas las cuales poseen la capacidad de dividirse y de proliferar indiscriminadamente.

Plant and animal cells are both eakaryetic cells and have many cell organisms in common. However the cells do have differences
denis-greek [22]

Answer:

Certain cell organelles are present only in plant cells like chloroplast and certain only in animal cell like centrioles.

Explanation:

The concept can be explained in three stages:

  1. <u>Organelles only in plant cells</u>- <em>Chloroplast</em> is an organelle which is helpful in photosynthesis. Since animals don't perform photosynthesis, they don't need it. Plant cells also have a <em>cell wall</em> on top of a cell membrane.
  2. <u>Organelles only in animal cell</u>- <em>Centrioles</em> are present in animal cells which help in movement through structures like <em>flagella and cilia.</em>
  3. <u>Organelles present in both plant and animal cells</u>- <em>Ribosomes, nucleus,mitochondria, golgi complex, cell vacuoles, lysosomes</em> are present in both plant and animal cells.
