DNA Structure
Watson and Crick used this term to describe the shape of DNA.
What is a double helix?
The importance of "start" and "stop" codons.
What tells the ribosome where the protein instructions begin and end?
The four nitrogen bases of DNA.
What are Adenine, Thymine, Cytosine, and Guanine. (A, T, C, G)
This is where DNA replication takes place.
What is the nucleus?
A 3-base sequence of nitrogen bases.
What is a codon?
Make up the sides of the DNA molecule.
What are sugars and phosphates?
The effect of an addition or a deletion of one of the bases in a codon.
What could throw off an entire sequence, call for a different amino acid, result in a different trait?
Always pairs with Cytosine.
What is Guanine?
This is where transcription takes place.
What is the nucleus?
The main function of mRNA.
What carries the information necessary for protein synthesis?
What the double helix shape looks like.
What is a twisted ladder?
When mRNA is made from DNA.
What is transcription?
Always pairs with Adenine in DNA.
What is Thymine?
This is where translation takes place.
What is the cytoplasm or ribosomes?
A change in a DNA strand.
What is a mutation?
The 3 parts of a nucleotide.
What are a nitrogen base, deoxyribose, and a phosphate?
When information contained in RNA is used to direct the sequence of amino acids during protein synthesis.
What is translation?
Always pairs with Adenine in RNA.
What is Uracil?
This is what holds the mRNA strand in place while translation proceeds.
What is the ribosome?
The three types of mutations to a DNA strand.
What are addition, deletion, and substitution?
A strand of DNA is made of 11% Adenine, this is how much Cytosine is present.
What is 39%?
The steps of protein synthesis.
RNA is transcribed from DNA in the nucleus.
mRNA leaves the nucleus and travels to the ribosomes.
tRNA gathers the amino acids necessary and brings them to the ribosomes where proteins are made.
The mRNA strand that pairs with the DNA strand ATGACGTAC.
What is UACUGCAUG?
When mRNA is transcribed from DNA, it then slips through these to get into the cytoplasm.
What are the nuclear pores?
DNA is an abbreviation for this term.
What is deoxyribonucleic acid?
