DNA
Deoxyribonucleic Acid
What does DNA stand for?
What is the difference between DNA and RNA?
DNA can't leave the nucleus and RNA can leave the nucleus with a copy of DNA so it can be turned itto a protein.
What are nucleotides made up of?
1. a phosphate
2. deoxyribose sugar
3. nitrogen containing bases
What is mRNA?
copies instructions and carries it to the ribosomes.
Genetics
the study of heredity and the variation of inherited characteristics.
Rosalind Franklin
Who took the first picture of DNA?
What replaces thymine from DNA-RNA
Uracil
What is the shape of DNA?
The ladder is twisted into a shape scientists call a "Double Helix".
What is tRNA?
Carries amino acids to the Ribosomes and mRNA.
Carrier
a substance used to support or convey another substance such as a pigment, catalyst, or radioactive material.
James Waston & Francis Crick
Who discovered DNA structure?
Why is RNA necessary to act as a messenger? Why can't the code be taken directly from the DNA?
RNA acts like a messenger because it transfers the codes for the DNA since DNA is too big to fit through the nuclear pores
What is Adenine bond with?
What is Adenine bond with? Thymine
What is rRNA?
composes ribosomes
Codon
a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule
Never leaves the nucleus
DNA
How many strands does DNA have and how many does RNA have?
DNA has 2 strands and RNA has 1 strand
What is Guanine bond with?
Cytosine
Mutation
the action or process of mutating.
Double Helix
What looks like a ladder, twisted around itself?
What bases are found in DNA/RNA?
What are 4 bases of DNA?
1. Adenine
2. Guanine
3. Cytosine
4. Thymine
DNA & RNA
The structure of DNA and RNA. DNA is a double helix, while RNA is a single helix.
