the process of producing two identical replicas from one DNA molecule
What is replication?
100
stores and transmits genetic information from one generation from organism to another.
What is the function of DNA?
100
to make protein (protein synthesis)
What is the function of RNA?
100
premature stop codon, making the protein incomplete
What is nonsense mutation?
200
Base is inserted or removed from the DNA (causing everything to shift)
What is point mutation?
200
ribose nucleic acid
What is RNA?
200
1)5-carbon sugar
2)Phosphate group
3)Nitrogenous Base
What is the function of DNA structure?
200
mRNA, rRNA, and tRNA
What are the three types of RNA?
200
- each resulting cell is complete set of DNA molecules
- each strand is used as a template for a new strand
- each resulting DNA = one new strand and one old strand
What does replication ensure?
300
a mutation that changes the protein.
What is a missense mutation?
300
the base that substitutes thymine RNA
What is uracil?
300
Used x-rays diffraction to find the clues to reveal DNA structure
(double helix)
Who is Rosalind Franklin?
300
process of copying an RNA molecule by copying a sequence of DNA
What is transcription?
300
Adenine,Thymine, Guanine, Cytosine
What are the 4 bases in DNA?
400
a change in the whole chromosome.
What is a chromosomal mutation?
400
adenine, thymine, cytosine, guanine
What are the four bases of DNA?
400
They created the first model of the double helix.
Who are James Watson and Francis Crick?
400
ribosomes read the instructions of the mRNA and assemble the polypeptide chains that result from coding the mRNA
What is translation?
400
This type of RNA carries copies of instructions and acts like the messenger in DNA
What is mRNA?
500
Down's syndrome
What is an example of a chromosomal disease?
500
1) adenine pairs with uracil
2) one strand of only
3) can leave the nucleus
What are the differences between RNA and DNA?
500
He discovered that the number of Adenine is equal to Thymine, and Guanine is equal to cytosine
Who is Erwin Chargaff?
500
translation happens here:
What is the cytoplasm/ribosome of the cell?
500
holds two strands together proving Chargaff's rules
