100
The longest phase of the cell cycle
(What is) Interphase
100
Organelle that packages protein
(What is) the golgi body
100
The specific order of nucleotides.
(What is) DNA sequence?
[acceptable: DNA code]
Note: sugar and phosphate do not change and are NOT part of the DNA code/sequence
100
The offspring from asexually reproducing organisms are.
(What is) identical to the parent
100
The cell division process of growth and replacement of old/damaged cells
(What is) mitosis?
100
In the process of meiosis, one diploid (2n) body cell gives rise to
(What are) 4 haploid (n) gametes
100
The stage of Meiosis shown below
(What is) metaphase II
The clues:
Metaphase = middle of the cell
II = two cells & sister chromatids (not paired homologous chromsomes) are separating
100
The first stage of human prenatal development (first 8 weeks)
(What is) the embryo stage
200
The number of chromosomes in human
A) Body cells
B) Gametes
What are
A) 46 (body cells are diploid, 2n- one from each parent)
B) 23 (gametes are haploid, 1n- half the number of chromosomes)
200
Cells that lack a true nucleus
What is a prokaryotic cell
200
The DNA base pair rule
(What is)
-A=T (A binds with T)
-G=C (G binds with C)
200
The method in which bacteria are able to reproduce.
(What is) binary fission
200
The final stage of the cell cycle.
(What is) cytokinesis?
200
In sexual reproduction, the product of the fusion of gametes
(What is) a zygote
200
The phase where homologous chromosomes pair up and "cross over" to exchange DNA
(What is) prophase I
200
The second stage in embryonic development
What is the fetal stage
300
The name of paired chromosomes.
(What are) homologous chromosomes
300
The organelle known as the "powerhouse of the cell"
What is the mitochondria
300
The central structure that holds sister chromatids together
(What is) a centromere
300
The method of asexual reproduction used by flatworms and starfish to grow a new organism from parts of the organism
(What is) fragmentation
300
Fruit fly body cells have 8 chromosomes.
The number of chromosomes in a daughter cell after mitosis
(What is) 8?
Mitosis starts with one diploid cell (2 copies of chromosomes) and ends with 2 diploid cells (2 copies of chromosomes)
300
The advantage sexually reproducing organisms have over asexually reproducing organisms.
(What is) diversity and therefore the ability to adapt
300
What phase of meiosis does this cell represent?
(What is) Metaphase I?
Clues: Metaphase = middle, 1 cell, homologous chromosomes are paired in the middle of the cell
300
The name of the cell when the sperm and egg cells fuse
What is the zygote
400
The environment required for an organism to reproduce.
(What is) ideal nutrients and temperature for survival.
400
The "brain" of the cell that controls all cell activities
What is the nucleus
400
Name for duplicated chromosomes
(What are) Sister chromatids?
400
The parts of a plant that can be used during vegetative propagation to grow into a new plant.
(What are) -stems, roots, leaves
400
The reason cells must duplicate their DNA before division.
(What is) so the daughter cells have the correct number of chromosomes after division
400
Disadvantages for organisms to reproduce sexually
(What are)
-Time/competition to find a mate
-Energy to raise offspring
400
The event(s) that occur during telophase II of meiosis?
(What is)
- The formation of 4 nuclei (almost 4 haploid cells)
400
The stage of embryo development immediately prior to implantation on the uterus wall
What is a blastocyst
500
The reason students should study/review
(What is) it helps them retain information!
500
The smallest unit of life
What is a cell
500
The 3 groups within a nucleotide of DNA
What are
1. Phosphate group
2. Deoxyribose sugar group
3. Nitrogenous base (the thing that changes and is "read" as DNA code or DNA sequence)
500
The asexual reproduction process used by yeast cells
What is budding?
500
The 3 stages of the Cell Cycle
What is:
1) Interphase (Growth, Development, DNA duplication)
2) Mitosis (Cell division)
3) Cytokinesis (Cell cutting)
500
Reasons siblings are different from each other
(What is) meiosis drives diversity:
-variation when chromosomes combine (crossing over)
-Variation in how chromosomes sort/separate
-Variation of merging gametes
500
The output of Meiosis
(What is)
the creation of gametes
Or: 4 haploid cells (haploid= half the number of chromosomes found in body cells)
500
The order of Human Embryonic development.
What is:
1. Egg + Sperm
2. Zygote
3. Embryo (8 weeks)
4. Fetus (30 weeks)
