There are Rules, People!
This person used X-ray images to confirm DNA's shape, but her work was stolen by another scientist.
Who is Rosalind Franklin?
The building block/ subunit of DNA.
What is the nucleotide?
The first step of DNA replication involves the DNA double helix doing this.
What is untwisting and opening up down the middle?
After the DNA double helix opens up and splits down the middle, _______________ can be made. It is a copy of the DNA code.
What is mRNA?
The structure made of DNA molecule and proteins that help it fold.
What is a chromosome?
These two scientists created the first 3-D model of DNA, but they also stole another scientist's work to complete it.
Who are James Watson and Francis Crick?
The three parts of the nucleotide.
What are sugar, phosphate and base?
This is the definition of replication.
What is making an identical copy?
After mRNA is made, it travels to this part of the cell.
What is the ribosome?
A section of DNA that codes for a specific protein.
What is a gene?
This rule states that the AMOUNT of A always matches the amount of T, and the amount of C always matches the amount of G.
What is Chargaff's rule?
The name of the sugar in DNA
What is deoxyribose?
In the second step of replication, these attach to the open strands.
What are free-floating nucleotides?
3 nucleotide bases will code for this many amino acids.
What is ONE amino acid?
What is 46?
This rule states that A will pair up with T because their shapes fit together. It also says C will pair with G because their shapes go together too.
What is the Complementary Base-Pairing Rule?
If DNA looks like a twisted ladder, the outside parts of the ladder are made of this.
What are sugar and phosphate?
In the third step of DNA replication, these are linked together.
What are the sugar-phosphate backbones of the new nucleotides?
These each carry one amino acid to the ribosome.
What are tRNA?
Chromsomes that are the same size and shape, and carry the same genes.
What are homologous chromosomes?
The full name (first and last) of the man who came up with Chargaff's rule
Who is ERWIN Chargaff?
If DNA looks like a twisted ladder, the inside parts of the ladder are made of this.
What are the four bases?
This happens in the last step of DNA replication
What is the two identical copies both retwist into helix shapes?
The ribosome does this to the amino acids.
What is connects amino acids together to form a protein?
The different form/ version of a gene.
What is an allele?
