What is DNA?

You hear the word DNA all the time. On television, the bad guy (or girl) is always caught because their DNA was found at the crime scene. So, what exactly is DNA?

DNA, also known as deoxyribonucleic acid, is a long, two-stranded molecule that has your personal genetic code. Similar to a cookbook, it holds all the recipes that make up the protein in your body.

Your genome is made up of your DNA. If you are wondering what genome is, it is an organism’s complete set of genetic instructions. Interestingly, each genome contains all the necessary information to create an organism.

Your DNA contains four basic building blocks: adenine, cytosine, guanine, and thymine. The order of these building blocks develops the instruction of the genome.

DNA is shaped like a twisted ladder or two strands of the candy Twizzlers. Each of the two strands of DNA has a beginning (five prime) and an end (three prime). They run in opposite direction of one another, so one strand is 5’ 3’ and 3’ 5’.

The genome for humans is made up of more than three million bases of DNA. The reason is that other organisms have different genome sizes.

Transcription in the Cell

One of the main reasons that we study cells and their development is to gain a deeper understanding of ourselves as the beings that house the cells.

Without cells, we would cease to exist.

Cells in our bodies, an other animal bodies is what allows us to gain energy via secondary source from the sun, build our bodies using the elements provided within our environment and obtain oxygen to feed those cells and keep them working properly.

Cells basically rely on a process called Cellular Respiration (to be discussed) and in it’s easiest form can be said in this way:  We eat food and breathe so that we release energy.  That energy is then used in our bodies to take care of the biochemical processes that are needed for life. (more…)

BUWOW Biology – The Cell

cells

Cells.

They are everywhere!

If you were to take a small toothpick and scratch the surface of your skin or even the inside of your mouth and put that on a microscope slide, you would be delighted to see hundreds of tiny little units with small dots in the center of them.

These are called cells and are 100% what you are made up of. (more…)

Buwow Biology – Characteristics of Life

Lesson 1:

The Characteristics of life.

There are many things in this world that we live in, however the ones that are living have the same characteristics of another and allow us to distinguish living from non-living.

The term organism refers to living things.

To say that all organisms have the same characteristics of life is accurate and would include the traits that will be mentioned in this post.

Some living things may make us think that they are not living and therefore, it is essential to know the characteristics of life in order to understand the world, living things and yes even ourselves, better.

Before the 1600’s people use to think that nonliving things would magically turn into living things.

Here are some examples of the funny things people use to think:

  1. Straw turned into mice.
  2. Grain turned into mice.
  3. A buried oxen head turns into a fly.
  4. Meat makes flies.
  5. Fruit turns into flies.
  6. Water made Frogs.

These are silly aren’t they?

But this was all before the cell was seen and before anyone knew the characteristics of living things.

The characteristics of living things follow some very general rules that allow us to determine if they are alive or not.

Here are six characteristics of living things used by scientists:

  1. All living things are made of cells (more about cells in another post…this is HUGE!)
  2. All living things need and use energy.  (They get it from the sun.  Some use it directly while other have to obtain it indirectly)
  3. All living things GROW and DEVELOP.
  4. All living things make more living things – Reproduction.
  5. All living things respond to their environment. (response and stimuli)
  6. All Living things adapt to their environment

In order to be considered alive, ALL of the characteristics of living things MUST be followed at some point in their life cycle. A good example of something that has some of these characteristics but is not alive is camphor.

If you take a bit of camphor and put it into water it will buzz around like it is alive (response to environment) but it is not living and it does not reproduce no is it made of cells.

Can you think of some other examples of nonliving objects displaying living characteristics?

 

第1課:

生活的特點。

有在這個世界上很多事情,我們生活在,但那些生活有另外一個相同的特點,使我們能夠區分非居住生活的人。

術語微生物指的是生活的東西。

說所有的生物體具有相同特性的生命是準確的,將包括將在這篇文章中被提及的特質。

一些生活的事情可能會讓我們覺得他們是不是生活,因此,有必要知道生活的特點,以了解世界,生活的東西,甚至是我們自己,更好。

在1600年人們用它來認為,非生物會神奇地變成生活的東西。

這裡是人們用來思考的有趣的事情的一些例子:

秸稈變成了老鼠。
糧食變成了老鼠。
掩埋牛的頭變成了一隻蒼蠅。
肉類,使蒼蠅。
水果變成蒼蠅。
水製成的青蛙。
這是愚蠢的,不是嗎?

但是,這是所有的細胞被認為之前,任何人之前就知道生物的特性。

生物的特點遵循一些很一般的規則,使我們能夠確定他們是否還活著與否。

以下是科學家使用生物六大特點:

一切生物都是由細胞(更多有關細胞在另一篇文章......這是巨大的!)
所有的生物都需要和使用能源。 (他們從太陽得到它。有些直接使用它,而其他的都間接地獲得它)
萬物發展壯大。
所有的生物都賺更多的生活的東西 - 繁殖。
所有的生物都應對自己的環境。 (反應和刺激)
一切生物適應環境
為了被認為是活著的,所有的生物的特性必須遵循在其生命週期的某個點。的東西,有一些這樣的特點,但不是活的一個很好的例子是香樟。

如果你需要一些樟腦,放入水中會發出蜂鳴聲周圍像它是活的(應對環境),但它不活,它不會重現沒有是由細胞組成的。

 

 
你能想到的無生命的物體顯示生活特點的其他一些例子嗎?
