DNA
The percentage of adenine in double stranded DNA where the percentage of thymine is 22%
What is 22%?
This process is the result of combining genes from diferent organisms.
What is recombination?
This process results in new alleles and and variations in a population
What is natural selection?
These molecules make up the backbone of DNA
What is deoxyribose and phosphate?
This 3-nucleotide sequence determines an amino acid
What is a codon?
This sugar is not found in DNA.
What is ribose?
These molecules cut double stranded DNA at specific sequences.
What are restriction enzymes?
2pq represents this in the Hardy-Weinberg equilibrium
What is the percentage of heterozygotes?
The reason that telomeres are not found in procaryotes
What is a circular chromsome?
This process converts double stranded DNA into single stranded RNA
What is transcription?
The complement to the following:
GGCTAGT
What is CCGATCA?
In gel electrophoresis, these pieces of DNA tend to move faster.
What are small pieces?
The reason homologous structure provide evidence for evolution
What is that they show common ancestors that gradually change over time?
This ocurs when only a small number of the original population survives
What is the Founder effect?
Non-codng sequences of RNA
What are introns?
During splicing this is removed.
What are introns?
The purpose of gel electrophoresis
What is to separate out fragments of DNA?
This structure represents a body part with little or no current function
What is a vestigial structure?
During the drought, the finches with bigger beaks survived.
What is the ability of these finches to crack open bigger seeds?
mRNA to protein: the process and where it takes place
What is translation and the ribosome?
This type of DNA replication results in each molecule having one new strand and one original strand.
What is semi-conservative replication?
These molecules are the sequence locator in PCR
What are primers?
These structures have similar functions but different evolutionary origins
What are analogous structures?
Hershey ancd Chase's experiments showed that bacteria are transformed by what molecule
What is DNA?
In the Hardy-Weinberg equilibrium, this equation represents the alleles
What is p + q =1?
