How To Study Or Review Any Scientific Concept? Ex.Molecules That Build Our Genes.


y virtualbiotutor[google5766b108e7b63aa1.html • Posted in

Follow these steps to study any scientific concept:

  1. Study the title of the topic & find the terms (words) that you don’t know.
  2. Define these terms.
  3. Read the first paragraph & start to outline the information using a concept map.
  4. Study this concept map  of the structure of DNA Molecule.

DNA   Strucure

  •                   Use this concept map as a guide line to create your own map.
  •                   Break down the map into smaller  sections, then  combine all to get the last version of the concept.
  •                    use similar colors to highlight similarities.
  •                     Explain or review the topic with a friend.
  •                      Answer the review questions to check your understanding of the concept that you studied.
  •                      Consult with your teacher to help you with the difficult points of the topic.

Inheritance of genetic traits


HSOffspring inherit their genetic traits that make them look like their parents, through  genes contained in the chromosomes during the process of reproduction.All body cells of an organism have identical genetic information,yet are different in structure and function.  The explanation for this variation in cellular structure,  is that  different  parts of the genetic  instructions are used in different cells and gene expression is  influenced by the cell environment and past history.

Check the power point presentation to get more information.

Embryonic Development


We Will follow the development of a fertilized egg from a zygote  to a baby. It’s fascinating to see how a single cell develops  and grows into a complete baby.

check your vocabulary through these introductory questions and follow the power point presentation to check your understanding of the process of development


Embryonic Development

How Does A Zygote develop into An Embryo?

Define the term embryonic development.

The changes from a zygote to a baby.

What will happen to the zygote after fertilization?

It undergoes the process of cleavage.

What is the end result of cleavage?

A  ball of cells called a morula is formed,then changed into a blastula.

Meiotic cell division Meiosis


Facts about meiosis.

Meiosis involves two cell division.
It produces cells that are different from the parent cell. Each cell has .one-half the number of chromosomes as the parent cell.
Meiosis takes place during sexual reproduction, producing sex cells ( eggs & sperms ).
It takes place in the sex organs (ovaries & testes)

Let us explore how meiosis  happens.

Check the power point presentation.
