Reproduction
This type of reproduction requires only one parent.
What is asexual reproduction?
DNA is copied in this phase before mitosis occurs.
What is interphase/S phase?
The products of meiosis are these types of cells.
What are gametes? What are haploid cells?
The probability of having an offspring with a recessive phenotype when crossing 2 heterozygous parents.
What is 25%?
RNA polymerase is the main enzyme in this process.
What is transcription?
In sexual reproduction, offspring receive this amount of genes from each parent.
What is 50%? What is 1/2?
This happens after telophase, and is what finalizes the separation of the daughter cells.
What is cytokinesis?
Crossing over occurs during this phase of meiosis.
What is prophase I?
Black colored fur (B) is dominant and white colored fur (b) is recessive in mice. A black coated mouse and white coated mouse are crossed and yield only black coated babies. Therefore, the black coated parent's genotype was this.
What is BB? What is homozygous dominant?
Helicase unzips the DNA in this stage of the central dogma.
What is replication?
This type of reproduction is more advantageous for very stable environments.
What is asexual reproduction?
There are 3 things formed during telophase. They are ___________.
What are 2 new nuclear envelopes and a cleavage furrow?
In this phase of meiosis, sister chromatids are pulled apart.
What is anaphase II?
A white flower and a red flower are crossed and produce pink offspring. The pattern of inheritance for these flowers is _________.
What is incomplete dominance?
One amino acid in a protein is changed to form a mutant, but still functional protein. The mutant protein is the result of this type of mutation.
What is a substitution mutation? What is a missense mutation?
This type of reproduction involves the union of gametes to create a new organism.
What is sexual reproduction?
Chromosome condense and become visible in the cell during this phase.
What is prophase?
In this phase of meiosis, homologous pairs of chromosomes line up in the middle of the cell.
What is metaphase I?
A white dog with brown spots has one brown coated parent and one white coated parent. The pattern of inheritance for the coat color of these dogs is _____________.
What is co-dominance?
The RNA sequence coding for a polypeptide chain looks like this:
AUG|CAG|UUG|UAC|UGA
The amino acid sequence would be _______.
What is:
Met|Gln|Leu|Tyr|Stop ?
Only organisms that do this type of reproduction have some cells that undergo meiosis.
What is sexual reproduction?
The mitotic spindles attach to the chromosomes in this phase.
What is metaphase?
After the first division, the two daughter cells are this. (1n or 2n)
What is 1n?
The alleles for blood types A and B are co-dominant to each other, and the allele for O is recessive to both. Therefore, there are 4 blood types A, B, AB, and O. A parent with A blood and a parent with B blood are crossed. Their children have an equal probability of having any of the four blood types. The genotypes of the parents must be ___ and ___.
What are AO and BO?
In the ribosome, mRNA binds with this molecule that brings the amino acid to the growing polypeptide chain.
What is tRNA?
