DNA Structure
The coiled, double stranded structure of DNA.
What is a Double Helix
This is the name of the DNA strand that replicates in fragments.
What is the lagging strand?
This nucleobase (base) replaces thymine in RNA strands.
This is the name for the type of RNA that translates mRNA into amino acids.
What are tRNA's?
a change in the DNA sequence that may cause alteration in the genetic message
What is a mutation?
This is the basic subunit of a DNA strand.
What is a nucleotide?
This is the name of the short fragments of DNA that are created on the lagging strand in DNA replication.
What are Okazaki fragments?
This type of RNA carries important coding regions from the nucleus to the ribosomes.
What is mRNA?
The site where mRNA is translated to proteins
What are ribosomes?
A mutation that causes a change in base pairs, with no effect on Amino Acid sequence.
What is a Silent Mutation
These bonds bring together complementary base sequences in DNA.
Hydrogen Bonds
This is the name of the enzyme that seals together DNA from the lagging strand.
What is ligase?
This is the location of the process we refer to as transcription.
What is the nucleus?
3 bases that are read at a time produce one amino acid
What is a codon?
Radiation, evolution, UV rays are all examples of these types of mutation factors.
This pair of scientists with help from Rosalind Franklin discovered the modern day DNA structure.
Who are Watson and Crick?
This is the name of the enzyme that unzips, or unwinds DNA helixes at the hydrogen bonds.
What is helicase?
This is the corresponding RNA sequence for the? following DNA strand: AGGCTA
What is UCCGAU
This amino acid is commonly identified by its codon GUC.
What is valine? What is val?
This class of mutations changes already existing bases into different bases.
What are point mutations?
These are the three most important structures found on a DNA nucleotide.
What are deoxyribose sugars, phosphate groups, and DNA bases?
This is the enzyme that synthesizes new complementary DNA bases from a parent strand.
What is DNA Polymerase
This is the name of the enzyme that produces RNA bases from a DNA sequence.
What is RNA polymerase?
What is a polypeptide chain?
This mutation is caused by the insertion or deletion of a base in a DNA sequence.
What is a frameshift mutation?
