Linear Regression – Best Fit Line

    1.  A linear regression – or best-fit line – attempts to represent data points in a scatter plot as a representative trend.
    2. Equation: $y = mx + b$

$y$ = $y$ variable
$m$ = slope
$x$ = $x$ variable
$b$ = $y$ intercept

Examples of positive correlation, negative correlation and no correlation.

DNA Structure - (Activity 1.3.1 - DNA Detectives)


Structure: 
A phosphate group, deoxyribose sugar and a nitrogen base are all the components that make up a nucleotide. The organization of each structural component can be seen to the right.

 

Function: Nucleotides are marcomolecule-monomers that can be brought together to create a DNA polymer; they are the ‘building blocks’ of DNA.

Polymerase Chain Reaction - (Activity 1.3.1 - DNA Detectives)

Step 1 – Denaturation

  1. Raise the temperature.
  2. As a result, the hydrogen bonds in the DNA double strand break and the molecule separates into two separate DNA single strands. (Excuse the alliteration!)

Step 2 – Annealing

  1. Cool the temperature down a bit.
  2. This will allow primers to attach to complimentary sequences on each of the single stranded DNA.
 

Step 3 – Elongation

  1. Slightly raise the temperature
  2. Taq polymerase will interact with the DNA-primer complex and begin to add nucleotides to the 3′ end of the primer. These nucleotides will be complimentary to whatever nucleotides are on the DNA strand.

Restriction Enzymes - (Activity 1.3.1 - DNA Detectives)

Origin: Restriction enzymes are produced by bacteria to protect the bacterium from foreign, viral DNA.

Function: They recognize a short, specific nucleotide sequences and separate the DNA strands at precise locations.

Application: Scientists have isolated restriction enzymes from bacteria and used them for techniques like genetic cloning and gel electrophoresis.

DNA Gel Electrophoresis - (Activity 1.3.1 - DNA Detectives)


Purpose
: DNA gel electrophoresis attempts to separate DNA fragments according to the size of the fragments. 

 

Function: The DNA sample is loaded into the wells of the gel and a current is applied to the electrophoresis chamber which also contains a salt water buffer. The DNA is moves towards the positive electrode in response to an applied current. Larger DNA fragments move slower through the agarose molecules in the gel.

 

Application: Gel electrophoresis can be used to analyze and compare the RFLPs of an unknown genetic sample to known genetic samples. For example, DNA evidence at a crime scene can be compared to a series of potential suspects.
