Fun Q & A
How many cells do humans have?
approximately 10 trillion cells
how many stands makeup DNA?
two strands
when you turn "A" into RNA what does it change to?
"U"
what is DNA psychology?
ability to identify specific genes that affect human behavior
What is the evolutionary history of the human genome?
rearrangement of existing genes. As well as the generation of new genes by duplication followed by mutation
Who discovered DNA?
Friedrich Miescher
do chloroplasts have DNA?
Each chloroplast contains a single DNA molecule present in multiple copies
what is a codon?
a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule
what is hereditability?
extent to which differences in a trait can be attributed to our genetic makeup
What are the types of genomic sequencing?
What does DNA stand for?
Deoxyribonucleic acid
How do cells make accurate copies of DNA?
When a cell divides, replicates DNA and makes new copies along the single strands of the original DNA
when do cells duplicate their DNA?
during the synthesis phase or S-phase of the interphase
What people do the paternity DNA tests, test?
between a father and child
How do genome sequences differ among people?
Every human genome is different because of mutations—"mistakes" that occur occasionally in a DNA sequence
Does DNA affect behavior?
Human behavior is subject to genetic variations.
What are the four pairs of DNA bases that form in the double helix?
adenine (A), cytosine (C), guanine (G), or thymine (T)
what is a mutation?
a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors
How many cells in our body have DNA?
Almost all of our cells have DNA, other than our red blood cells.
What genomic sequence differences lead to human disease?
The comparison of Watson’s genome with the human reference sequence led to the identification of SNPs, plus small indels and CNVs
Do we share any DNA with primates?
Yes, we share 96% of our DNA with primates such as chimpanzees, gorillas, and orangutans.
What is DNA shaped like?
a twisted ladder
what are the two major steps to make protein?
Transcriptions and Translations
Can any animals edit their genes?
Actually yes, octopi can edit their own genes.
how does the human genome work and what variants in our genomes make us more prone to illness?
No; only a small percentage of variants cause genetic disorders
