To interpret a DNA to protein chart, start by identifying the DNA sequence in groups of three nucleotides called codons. Each codon corresponds to a specific amino acid. Use a genetic code chart to match each codon to its corresponding amino acid. Then, read the amino acids in order to determine the sequence of the protein that the DNA codes for.

Explain why the addition of an extra base in a DNA sequence would change the message carried by a DNA molecule?
The addition of an extra base in a DNA sequence would cause a frameshift mutation, shifting the reading frame of the genetic code. This would alter the codons specifying amino acids in the protein sequence, leading to a different protein being produced.
How does chromatin immunoprecipitation work to identify protein-DNA interactions?
Chromatin immunoprecipitation (ChIP) is a technique used to study protein-DNA interactions. It involves cross-linking proteins to DNA, breaking the DNA into small fragments, and then using an antibody to pull down the protein of interest along with any DNA it is bound to. The DNA fragments can then be analyzed to identify the specific regions of the genome where the protein is interacting with DNA.
How does EMSA electromobility shift assay measure whether the protein bends DNA?
EMSA measures protein-DNA binding by observing the mobility shift of the DNA-protein complex in a gel electrophoresis system. When a protein binds to DNA, the complex migrates more slowly in the gel due to its larger size and altered shape. This shift in mobility indicates protein-induced bending or conformational changes in the DNA.
Does a DNA mutation always result in a change to the protein?
No, a DNA mutation does not always result in a change to the protein. Some mutations are silent and do not affect the protein's function.
What role does ssb protein play in DNA replcation?
The ssb protein, or single-strand binding protein, helps stabilize single-stranded DNA during DNA replication. It prevents the single-stranded DNA from forming secondary structures and protects it from degradation by nucleases. This allows DNA polymerase to efficiently bind and synthesize the complementary DNA strand.
What 2 processes interpret the information in a DNA molecule and result in a protein byproduct?
Transcription to mRNA in the nucleus then translation by ribosome. (I think!)
In gene expression and protein synthesis information flows from?
DNA --> RNA --> Proteins -----------------------------------------That simple.
When the genetic material was first being isolated and studied there was a controversy about it being DNA or protein-- those that backed protein as the genetic material almost got it right-- explain?
Scientists thought genetic material was a protein not DNA because there are 20 different amino acids for a building of a protein polymer, while DNA polymers only have 4 nucleotide bases.
What tells ribosomes how to assemble a protein?
DNA tells a ribosome how to assemble a protein.
How does DNA determine a protein's shape?
DNA determines a protein's shape by determining the sequence of the amino acids in a protein.
What describes pieces of DNA to make protein?
A gene is a segment of DNA that codes for a protein.
What 11 letter word is made of protein and DNA?
Chromosomes are made of protein and DNA.
What does heat do to the DNA polymerase?
Heat denatures protein. DNA polymerase is an enzyme and a protein.
What is the action of a DNA binding protein?
dna binding protein binds the 2 anti parallel strands of dna together
What is DNA to RNA to protein?
Protein synthesis
Is DNA a protein or not?
That depends. DNA undergoing replication is assisted by varieties of proteins to make a new strand. Also, in order for DNA to be coiled into chromosomes, the DNA must be wrapped around the protein histone. But in the actual structure of DNA, no, there are no proteins.
Explain why the addition of an extra base in a DNA sequence would change the message carried by a DNA molecule?
The addition of an extra base in a DNA sequence would cause a frameshift mutation, shifting the reading frame of the genetic code. This would alter the codons specifying amino acids in the protein sequence, leading to a different protein being produced.
