Genetics DNA Technology Evolution Potpourri DNA & PS
Having two different alleles for a trait EX Tt is called this
Traits that have a bell curve of phenotypes (not just two or three) EX/ skin color, IQ, birth weight
How many chromosomes does a normal human have?
Where would you expect genes that assort independently to be found?
ON DIFFERENT CHROMOSOMES
If an organisms haploid number is 20, what is it’s diploid number?
What enzyme is used to add new DNA nucleotides to the new strands of DNA during DNA replication?
Which kind of RNA brings the copy of the gene from the nucleus to the ribosomes for protein synthesis?
Information in the cell goes from DNA RNA to what?
If a DNA sample contains 13% Adenine, how much Guanine would it contain?
This is where transcription takes place
In this process, external DNA is incorporated into a cell.
This process uses chopped up DNA in a gel to determine paternity or solve a crime
DNA created by combining DNA from more than one source
These “molecular scissors” are used to cut up DNA into smaller pieces
Changing the sequence of DNA of an organism
All of the genes in a population of organisms
Body parts that once were useful but no longer are (EX/remnants of 3 rd eyelid & appendix in humans)
Genetic drift tends to occur more frequently if a population is this
Natural selection acts upon these
PHENOTYPES PRESENT IN A POPULATION
When two species adapt and evolve in response to one another (EX/Bees and flowering plants)
The two-word naming system developed by Linnaeus
Using binomial nomenclature, which word gets capitalized?
GENUS ex/ Felis domesticus (Genus) (species)
Selection that favors the average phenotype (pressure against two extremes)
Failure of chromosomes to separate during meiosis
Genes contain the instructions for building these:
DNA/Genetics Test Review. What is DNA? DNA is our genetic blueprint. DNA is a double helix –It looks like a twisted ladder It is made up of nucleotides.
Genetics Ms Mahoney MCAS Biology. Central Concepts: Genes allow for the storage and transmission of genetic information. They are a set of instructions.
DNA Structure and Technology By: Amber Tharpe. DNA Structure Monomers are nucleotides Monomers are nucleotides 3 parts of a nucleotide 3 parts of a nucleotide.

SB2a How are DNA and RNA different? DNA is double stranded and RNA is single stranded. RNA has Uracil and DNA has thymine. DNA is only in the nucleus.

SC.912.L.16.3 DNA Replication. – During DNA replication, a double-stranded DNA molecule divides into two single strands. New nucleotides bond to each.
