General
Proteins are made of…
Amino Acids.
Interphase occurs during about __% of the cell’s life.
Interphase occurs during about 90% of the cell’s life.
List three physical features influenced by genetics.
Eye color, skin tone, height, etc.
Do personality traits effect intelligence?
Yes! Genes affecting a individual‘s motivation, personality and confidence have a big influence on their intelligence aswell
What is an anticodon?
Complementary to the mRNA codon, and represents one specific amino acid.
The most important impact of mitosis is…
That it ensures each daughter cells receives a full set of DNA.
Is bloodtype by chance or genetic?
It is genetic!
What type of trait is intelligence?
Intelligence is a “polygenic trait”, meaning that it is influenced by two or more genes.
Phosphate groups bonded with sugar molecules.
What is the correct order of events within the cell cycle?
G1, S, G2, Mitosis, Cytokenisis
Is the likelihood of a individual’s chance of developing a disease influenced by genetics?
Yes! Diseases and conditions can be passed down to offspring.
Fill in the blank: “Measured intelligence appears to increase over time,1. __ percent in infancy to 2. __ percent in childhood to 3. __ percent in adulthood”.
1. 20
2. 40
3. 60
What is the purpose of the centromere?
To hold the sister chromatids of each chromosome together.
What is the purpose of the DNA helicase?
“Unzipping” the DNA strand
What is the probability of having a child with a recessive genetic disorder when both parents are carriers of the trait but do not exhibit the disorder themselves?
1/4 or 25% chance.
What is the gene in our DNA code that effects our intelligence?
There is not one gene responsible for intelligence! Intelligence is influenced mostly by environmental factors rather than genetics. Thousands of genes play a role in developing intelligence.
What are histones used for?
DNA is wrapped around them in order to keep it intact/organized during division.
During Anaphase…
Chromosomes are pulled apart towards the center of the cell, with one identical copy moving to each pole.
Name the process by which segments of DNA are rearranged to produce a new combination of genetic material during the formation of gametes.
Yes! Studies found that from 37%-57% there is a heritability IQ.
