1. Cell starts into mitosis phase of the cell cycle.
2. Helicase begins to break the hydrogen bonds between the nitrogen bases. (The double helix has to be unwound in order to expose the nucleotides)
3. DNA polymerase attach the free-floating nucleotides to the exposed nitrogen bases. (this allows a new DNA strand to be made on the existing one)
4. Free floating nucleotides pair up with exposed nitrogen bases (this is what really builds the new strand, based around the template strand)
5. Two new molecules of DNA are created
Statements:
Adenine
Cytosine (Car in the Garage, Apple in a Tree is a good trick to know how they pair)
DNA
Replication
Double helix
"Gravitational attraction" is initially responsible for the formation of the clumps of matter within this interstellar cloud.
<u>Answer:</u> Option C
<u>Explanation:</u>
About 4.6 billion years ago, the solar systems were a bunch of gases and dusts, referred to solar nebula. Gravity squeezed the material as it started to rotate, creating the sun at the middle of the fog.
The rest of the material began to accumulate with the sunrise. The smaller particles moved together to form larger particles that were connected by gravity. As lumps develop, gravity increases and turns into kinetic energy of moving particles that collide and produce heat.
Answer:
<em>PROS: </em>
<em>1. They are cheaper</em>
<em>2. They contain more nutrients</em>
<em>3. Grown with fewer pesticides</em>
<em>4. Resistant to insects</em>
<em>5. Tolerance to heat, cold, and drought</em>
<em>CONS:</em>
<em>1. May cause allergic reactions</em>
<em>2. Will make you resistant to antibodies</em>
<em>3. Cross pollination</em>
<em>4. GMO's can create a super bug, one which is able to go past the crop's resistance on insects. Making a devastating blow on crops that have no insect resistance</em>
<em>5. They have been linked to cancer</em>
