A DNA molecule looks like a?
Twisted Ladder
Cars in a factory being made is an example of?
Engineered systems
Nucleotides are found in the ?
Nucleus of each cell
During _________ the new chromosomes reach opposite ends of the cell and begin to uncoil.
Telophase
The joining of gametes is called
Fertilization
Each section of a DNA molecule that codes for a unique protein is called a
Gene
When skills and knowledge were needed to make them
irreducible complexity
After a cell is done copying its organelles and DNA, its ready for the next phase of the cell cycle called?
Mitosis
The final state of the cell cycle?
Cytokinesis
The diploid cell tht results from fertilization is called?
Zygote
In this process ribosomes need working copies of the DNA that they can use to make proteins.
Transcription
As cells grow they prepare to reproduce. This process is called?
Cell Cycle
In this face the membrane around the nucleus disappears?
Prophase
This type of reproduction does not involve eggs?
Asexual reproduction
Reproduction using gametes
Sexual reproduction
Sets of three nucleotides in a row are called?
Codons
Cells spend most of their time in the _______ portion of the cell cycle.
Interphase
In this phase the chromosomes are lined up at the center of the cell.
Metaphase
Matching pairs of chromosomes are called?
Homologous
Deoxyribose and phosphate
Protein synthesis
Scientist call the DNA-copying process
Replication
During this phase sister chromatid pairs divide into separate chromosomes.
Anaphase
Similar to mitosis ________- begins with the number of genes in the parent cell
Meiosis
MRNA stands for?
(Messenger) Ribonucleic Acid
