Answer:
yes it is :) I hope this helps:)
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
Answer:
1) The ecosystem would have the abiotic factors of low precipitation, dry winds, and low temperatures. The biotic factors would include the animals living with the penguins such as polar bears and yaks.
2) The population would suddenly increase if either the penguin's predators had a drop in numbers or if the penguin's food source became more readily available. This growth in population would result in food becoming harder to find and predators once again growing in numbers. This would eventually cause the penguin population to shrink once more.
3) Predators would die out. Whatever organism(s) were the penguin's food source would grow in size exponentially. Other animals may suffer a drop in numbers if the penguin's predators choose to prey on them.
The correct order is: B) 2, 5, 4, 3, 1.
2. A segment of DNA is transcribed in mRNA. mRNA is transferred to the cytoplasm. This is the process of transcription that occurs in the nucleus of the cell and it is the first step of gene expression. It is performed by the enzyme RNA polymerase.
5. The mRNA strand is fed through the ribosome. Ribosome is an organelle where protein synthesis (translation) occurs and it consists of proteins and RNAs.
4. Molecule of tRNA delivers amino acids from to the ribosome. tRNA is transfer RNA because of its function to carry amino acids to the ribosomes during protein synthesis.
3.The amino acids are dropped off at the ribosome.
1. The amino acids are joined to make a protein. Amino acids are added to a growing protein chain.
