|
Replication =
|
Process of duplicating the DNA so the cell can divide
|
|
|
Where does Replication take place?
|
Nucleus
|
|
|
Transcription =
|
Process of making mRNA using DNA as a template
|
|
|
Where does Transcription take place?
|
Nucleus
|
|
|
Translation =
|
Process of building a protein using the mRNA
|
|
|
Where does Translation take place?
|
Ribosome
|
|
|
What is a protein made of?
|
Amino acids hooked together by peptide bonds
|
|
|
What is one way DNA is different from RNA?
|
DNA has 2 strands hooked together, RNA is one
|
|
|
What is another way DNA is different from RNA?
|
DNA has deoxyribose as the sugar, RNA has ribose
|
|
|
What is one way DNA is different from RNA?
|
A bonds with T in DNA, in RNA, A bonds with U
|
|
|
mRNA =
|
messenger RNA – made in nucleus, carries instructions for making a protein to ribosome
|
|
|
tRNA =
|
transfer RNA – brings amino acids to ribosome to build protein, tRNA is complimentary to mRNA
|
|
|
Nitrogen Bases =
|
A, T (U), G, C – bond together to form rungs on DNA “ladder”
|
|
|
Nucleotides =
|
Repeating unit that make up DNA and RNA
|
|
|
What are three parts of a nucleotide?
|
Sugar, Phosphate, and nitrogen base
|
|
|
What does Complimentary mean in terms of DNA?
|
Sides fit together because A – T and G - C
|
|
|
What happens at the Ribosomes?
|
Making of proteins in process of translation.
|
|
|
What processes happen at the Nucleus?
|
Replication and transcription
|
|
|
Amino Acids =
|
Proteins are made of amino acids molecules all hooked together
|
|
|
Codon =
|
3 base pairs of mRNA that code for a protein
|
|
|
Mutation =
|
Mistake in the DNA that results in the wrong protein being made
|
