Gene Regulation
100
During this phase, chromosomes are held at the poles of the cells after separation
What is telophase
100
Duplicated chromosomes have two of these that are connected by a centromere
What are sister chromatids
100
This gender is most susceptible to x-linked diseases
What is the male gender
100
The 3 components of nucleotides: including a phosphate group, deoxyribose sugar, and this
What is nitrogenous base
100
This represents the phase of translation that builds the chain of amino acids
What is elongation
200
During this phase, chromatin starts to condense in preparation for cell division
What is prophase
200
Classification of chromosomes inherited from each parent that are similar, yet not identical
What are homologous chromosomes
200
If black fur (B) is dominant over brown fur (b), someone who is Bb is said to be this gentoypically
What is heterozygous
200
With the following DNA strand (TAGCTAG), the complementary DNA base pairs would be this
What is ATCGATC
200
With the following DNA strand (TAGCTAG), the complementary mRNA base pairs would be this
What is AUCGAUC
300
The law of this states that daughter cells get random combinations of alleles from parental gametes
What is independent assortment
300
The function of this structure is to pull chromosomes or chromatids apart during cell division
What are spindle fibers
300
Pattern of inheritance whereby cells express proteins encoded by BOTH dominant AND recessive alleles
What is codominance
300
These are the types of bonds that hold complementary base pairs together
What are hydrogen bonds
300
This is the region of the gene where RNA polymerase binds
What is the promoter
400
The process by which cells specialize to perform a specific function
What is differentiation
400
Chromosomes line up independently of one another during metaphase of this method of division
What is mitosis
400
Nondisjunction of chromatid pairs occurs in this phase
What is meiosis II (anaphase II)
400
This describes a resulting DNA molecule after replication that has 1 old strand and 1 new strand
What is semiconservative
400
Units of prokaryotic DNA which contain unctionally related genes
What is the operon
500
Type of cell division that produces daughter cells with half of the information as parental cells is known as this
What is meiosis
500
During this phase, sister chromatids separate in order to eventually produce 4 haploid cells
What is anaphase II
500
If we cross two heterozygous pea plants, dominant vs. recessive phenotypes should be equal to this ratio
What is 3:1
500
These proteins proofread DNA replication
What are "DNA repair enzymes"
500
The pre-initiation complex encompasses the small ribosomal unit, other proteins, and this specific tRNA
