DNA Flashcards
The genetic code in DNA depends on the order of_______.
Nucleotides
what would the complimentary mRNA of this DNA strand be? Use capital letters and one space between each letter. T A C C C G A C C A T T (use caps and put one space in between each letter)
A U G G G C U G G U A A
Nucleotides
the building blocks of DNA
Chromosome
made up of genes
Gene
a section of a DNA molecule that contains the instructions for a specific protein
DNA
organic molecule that contains the instructions for all living things
Each tRNA attaches to a specific ______
amino acid
Transcription
where does it occur
nucleus
Translation
where does it occur
cytoplasm
What is the end result of transcription?
RNA
tRNA
Ribosomes would not have the amino acids they need to synthesize proteins
rRNA
Ribosomes would be missing a part and would not be able to synthesize proteins
mRNA
Genes’ instructions would not be able to leave the nucleus, so ribosomes would not have a blueprint they need to synthesis proteins
Place the steps of DNA replication in order from beginning to end.
The DNA helix untwists
Enzymes separate the 2 DNA stand
The new nucleotides are added by enzymes
2 identical DNA molecules are produced
Is the following strand a strand of DNA or RNA? How do you know? AUGGAU
RNA because only RNA has U’s
which of the following bases is not found in RNA
T
Translation
uses the mRNA code to create a protein in the ribosomes found in the cytoplasm
Replication
the creation of 2 sets of DNA for cell division. Unwinding and adding in new nucleotides
Transcription
using DNA as a template to create an mRNA code, which occurs in the nucleus
tRNA contains a three nucleotide part called a
Anticodon
tRNA attach to ____ and transfer them to the ribosomes
amino acids
In terms of DNA, a mutation is
a mistake in the DNA that can cause a protein to be made incorrectly, which may lead to various problems

How many codons are in this RNA sequence AUGGCCACAUAA?
4
Which seems to be the most accurate description of RNA?
A copy of a gene that can leave the nucleus
If one strand of DNA reads T C G A A T C G A, what would the complementary strand be? Use capital letters with 1 space between each letter
A G C T T A G C T
What type of RNA is involved in translation?
rRNA, mRNA, and tRNA
rRNA
the location where the proteins are made
tRNA
carries the amino acid
mRNA
the message using A, U, C, and G
A. T, G, C, and U are all examples of…
nitrogen bases
Which of the following is a segment of DNA that codes for a certain protein?
Gene
