Tightly wound DNA.
What is a chromosome?
The number of nitrogenous bases that DNA has.
What is 4?
The sugar in RNA.
What is ribose?
This number of mRNA bases in a row determines an amino acid.
What is 3?
The first unit to bind with an mRNA to begin translation.
What is the small subunit of a ribosome?
A cell possessing one copy of each chromosome.
What is haploid?
Cytosine normally pairs with this.
What is guanine?
This enzyme reads the gene to create the mRNA strand.
What is RNA polymerase?
The number of codons in the genetic code.
What is 64?
The part of tRNA with a complementary sequence for a codon.
What is an anticodon?
The process of mRNA being made from DNA.
What is transcription?
The structure of DNA.
What is a double helix?
These segments are cut out of mRNA before it is mature.
What are introns?
This part of DNA has the complementary sequence for genes.
What is the non-coding strand?
The growing chain of amino acids is called this.
What is a polypeptide?
The process of protein being made from mRNA.
What is translation?
When DNA is replicated, this is the number of new strands in the new DNA molecule.
What is one?
The mRNA that is made is a copy of this strand of DNA.
What is the coding strand?
The type of RNA that brings amino acids to a ribosome.
A type of mutation that can shift the reading frame of the mRNA codons.
What is a deletion or insertion mutation?
Heritable changes in gene expression NOT due to changes in DNA sequence.
What is epigenetics?
This type of bond holds the two strands of DNA together.
What is a hydrogen bond?
Mature mRNA attaches to a ribosome in this part of the cell.
What is the cytoplasm?
The type of RNA that is part of an organelle.
What is rRNA?
What is a master gene?
