Chromatin consists of DNA that is tightly coiled around these type of proteins.
What are histones
100
These are the three types of RNA
What are messenger, ribosomal, and transfer RNA
100
Gene mutations involving changes in one or a few nucleotides.
What are point mutations
100
Type of genes responsible for controlling the differentiation in cells and tissues during enbryonic development.
What are hox genes
200
This scientist used a technique called X-ray diffraction to get information about the structure of DNA
Who is Rosalind Franklin
200
Bead-like structures formed by DNA wrapped around eight histones.
What are nucleosomes
200
During transcription, this enzyme binds to DNA and separates th DNA strands. It then uses one strand of the DNA as a template from which nucleotides are assembled into a strand of RNA.
What is RNA Polymerase
200
In this type of mutation, a nucleotide is added or deleted, the bases are still read in groups of three, but now those groupings are shifted for every codon that follows.
What is a frameshift mutation
200
Cells don't just grow and divide during embryonic development, they also undergo THIS, which means they become specialized in structure and function.
What is differentiation
300
In 1928 by British scientist Frederick Griffith injected mice with two different strain of the bacteria that cause this
What is pneumonia
300
During this process, the DNA molecule separates into two strands, then produces two new complementary strands following the rules of base pairing.
What is DNA replication
300
This consists of three consecutive nucleotides that specify a single amino acid that is to be added to the polypeptide.
What is a codon
300
The condition in which an organism has extra sets of chromosomes.
What is polyploidy
300
A group of genes that operate together.
What is an operon
400
Oswald Avery discovered that DNA was the genetic makeup of a cell when he omitted, by process of elimination, proteins, carbohydrates, lipids, and RNA by destroying them with these highly specialized type of proteins.
What are enzymes
400
This enzyme joins individual nucleotides together as it replicates the original DNA into two daughter DNAs. It also "proofreads" each new strand, helping to maximize the odds that each molecule is a perfect copy of the original DNA.
What is DNA polymerase
400
The process of decoding an mRNA message into a polypeptide chain (protein)
What is translation
400
Translocation is one of these. There are four types of chromosomal mutations total.
What are deletion, duplication and inversion.
400
One of two regulatory regions in genes to which repressor proteins can bind.
What is the operator
500
Bacteriophages are viruses that destroy bacteria. By using radioactive markers on the virus' protein coat and DNA, these two scientists concluded that DNA, not protein, was the genetic material in cells.
Who are Hershey and Chase
500
In DNA replication, this enzyme creates the fork and unwinds and unzips the DNA molecule by breaking the hydrogen bonds that hold the base pairs together.
What is helicase
500
The DNA of eukaryotic genes contains sequences of nucleotides that are not involve in coding for proteins and some sequences that are.
What are introns and exons
500
An example of a frameshift mutation
What is Tay-Sachs Disease
500
In E.coli, this gene sequence is turned off by repressors, and turned on by the presence of lactose.
