DNA
The four bases in DNA
What are GCAT
DNA responsible for producing proteins is known as what?
Coding DNA or exons
Recombinant DNA involves moving _____ from a donor organism to a vector oragnism
genes
Meiosis only occurs in these specific types of cells
Gametes (sperm/egg)
A mutation that only affects a single nucleotide base
Point
A base that appears in RNA but not DNA
What is uracil?
This enzyme unzips the DNA double strand to expose bases to be copied during transcription
RNA polymerase
This first step in making recombinant DNA involves removing a target gene from a donor organism
Isolation
The number of chromosomes in a cell after meiosis is described as what
Haploid
A mutation in which a base is added or deleted, affecting the sequence from that point on
Frameshift
The sugar found in DNA
What is deoxyribose?
RNA polymerase can bind to DNA to these specific areas of a gene
Recognition sequence
This enzymes 'glues' corresponding sections of DNA together
DNA ligase
During metaphase, chromosomes line up in what grouping?
Homologous pairs
A mutation that has no effect on the peptide chain produced
Silent
This enzyme adds complementary bases to the expose strand during DNA replication
What is DNA polymerase?
Non coding introns are removed by enzymes during this final step of transcription
Post transcriptional modification
This process involves making a large number of copies of this new DNA
Amplification
During which phase does crossing over occur?
Metaphase I
This mutation involves one amino acid being substituted for another
Missense
This enzyme joins Okazaki fragments on the lagging strand during DNA replication
What is ligase?
These molecules bind with specific amino acids during translation
tRNA
These particular sections created by restriction enzymes allow DNA to join seamlessly with another DNA strand
sticky ends
The failure of chromosomes to separate correctly is called what
Non-disjunction
Only mutations in these cells are passed on to future generations
Germ line (reproductive)
