Structure of DNA
What is the shape of DNA?
Double Helix
The two strands of the DNA helix are held together by what type of bond?
Hydrogen bond
RNA consists of how many strands?
One strand
In RNA, what other base would Uracil pair with?
Adenine
What the abbreviation DNA stand for?
Deoxyribonucleic acid
What are the four bases that form the "ladders of DNA"
Adenine,Thymine, Guanine, Cytosine
What are the four bases that make up RNA.
Adenine, Uracil, Guanine, Cytosine
There are three types of RNA. What are they?
1. Messenger RNA (mRNA)
2. Transfer RNA (tRNA)
3. Ribosomal RNA (rRNA)
This contains the genetic information to form a new organism or cell and also has the information to produce proteins.
DNA
Guanine pairs with what other base?
Cytosine
RNA is made up of small units. What are they called?
Nucleotides
This type of RNA copies the code from DNA and carries it to the ribosomes.
Messenger RNA (mRNA)
DNA consists of small units. What are they called?
Nucleotides
Adenine pairs with what other base?
Thymine
In RNA, the nucleotides consist of what three things?
1. Phosphate group
2. Sugar (Ribose)
3.Nitrogen-carrying bases
This type of RNA brings the amino acids required by the code.
Transfer RNA (tRNA)
Nucleotides consist of three parts.
1. Phosphate group
2. Sugar (deoxyribose)
3. Nitrogen- carrying bases
The bases on DNA are attached to what?
Deoxyribose (a sugar)
RNA does not have the base Thymine. Instead, what base does it have?
Uracil (U)
This type of RNA binds the mRNA and tRNA
Ribosomal RNA (rRNA)
