DNA Structure
This term is used to describe the shape of DNA.
What is a double helix?
The number of molecules of DNA that are produced after replication.
What are two molecules?
This type of RNA carries the information from DNA to ribosomes so that proteins can be made.
What is messenger RNA (mRNA)?
This base pairs with cytosine.
What is guanine (G)?
This is what DNA stands for.
What is deoxyribonucleic acid?
These two things form the "backbone" of DNA.
What are sugars and phosphates?
The location in the cell where DNA replication happens.
What is the nucleus?
The type of sugar found in RNA.
What is ribose?
This base pairs with guanine.
What is cytosine (C)?
When a cell divides, DNA is coiled up (condensed) into these visible structures.
What is a chromosome?
This is what you call a "G" binding with a "C" or an "A" binding with a "T".
What is a base pair?
The nitrogen base found in RNA but NOT in DNA.
What is uracil (U)?
This base pairs with thymine in DNA.
What is adenine (A)?
This is a segment of DNA that codes for a protein.
What is a gene?
It is made up of a sugar, phosphate, and nitrogen base.
What is a nucleotide?
This type of RNA carries an amino acid to the ribosome in order to make proteins.
What is transfer RNA (tRNA)?
This base pairs with adenine in DNA.
What is thymine (T)?
This is what RNA stands for.
What is ribonucleic acid?
Who are Watson and Crick?
This is the enzyme responsible for unwinding and unzipping DNA during replication.
What is DNA helicase?
The type of RNA that makes up part of the ribosome.
What is ribosomal RNA (rRNA)?
The type of nucleic acid that doesn't have pairs because it is single-stranded.
What is RNA?
With RNA, A (adenine) binds with this other base.
What is U (uracil)?
