Questions to Consider:
Know the general work and findings of the following scientists:
Mendel was the founder of genetics. Many considered him to be the “father of modern
genetics.” This is because he demonstrated that the inheritance of certain traits in pea plants follows

creating the first cell with a synthetic genome.
What are three main parts of a DNA nucleotide?
The three main parts of a DNA nucleotide are
carbon sugar, phosphate, and four bases.
What are the three bases found withi
The four bases found in DNA are guanine and cytosine, and adenine and thymine.
What are the DNA base pair rules?
The DNA base pair rules are that G and C must always be together and A and T must always be together. And
also if you look at one seque
nce of DNA, then you will be able to find out the other sequence of DNA.
If one side of a DNA helix reads AAATCG what does its complimentary strand read?
The other side of the complimentary strand reads
How does a DNA double helix, chromosomes and
genes relate to one another?
A chromosome consists of a spiral of DNA (in the shape of a double helix) and the DNA consists of genes.
How do DNA and proteins relate to one another?
Proteins are t
ranslated to RNA.
And RNA is transcripted to DNA.
the overall charge of a strand of DNA?
The overall charge of a strand of DNA is negative.
How does DNAs charge help in electrophoresis?
The top of the gel electrophoresis is negative and the DNA is also negative. So you load the DNA at the top of
and the largest sized DNA will be stay at the top, while the smallest DNA will move to the bottom.
What is the goal of DNA electrophoresis?
The goal of DNA electrophoresis is to separate the largest DNA strands from the smallest DNA strands.
What is BLAST
and what does it do?
BLAST is a basic local alignment search tool. It compares different DNA samples to find the mutations in DNA
and find out what disease the person/organism has.
What are restriction enzymes
and how are they used in genetic engineering?
Restriction enzymes are enzymes that cut the DNA at a specific place. It is used in Genetic Engineering to check
if a particular gene present in a strand of DNA or not.
What are “sticky ends” and how do they relate to restriction enzymes.
An end of a DNA
double helix at which a few unpaired nucleotides of one strand extend beyond the other.
What is bioinformatics and how does it relate to the human genome project?
Bioinformatics is the collection and storage of data or information from sequencing. The go
al of the human
genome project was to store this information, read it (analyze), and improve data analysis.
What basic characteristics are used to identify different fingerprints?
Different fingerprints can be characterized by looking at whether the finger
print pattern is a loop, whorl, or arch.
What is the difference between a latent and patent fingerprint?
A latent fingerprint is a fingerprint that is barely visible. It is normally on a knife of countertop. A patent
fingerprint is a fingerprint that is
visible and is pressed into clay or something like that.
