Genes and Cell Division
These are located on chromosomes
What are genes?
Coded messages
What is DNA?
amino acids
What are proteins made of?
What are possible functions of mitosis?
This happens during interphase.
When is a cell's genetic material duplicated?
23 pairs or 46 chromosomes
How many chromosomes does a diploid human cell have?
Watson and Crick in 1953
Who worked out a model for the structure of DNA and when did they do it?
DNA-mRNA-protein
What is the sequence of events in forming a protein?
These are special reproductive cells having only 23 chromosomes (in humans).
What are gametes?
The cell's cytoplasm and organelles are divided, resulting in two new daughter cells.
What happens during cytokinesis?
interphase, mitosis, cytokinesis
What are the three stages of the cell cycle?
The four bases in DNA nucleotides
What are adenine, thymine, cytosine and guanine?
A codon codes for this.
What is amino acid?
Two organisms each give one complete copy of their genes to form a new organism.
What is sexual reproduction?
During this process, the offspring receive an exact copy of the parent's genetic material, making them identical to the parent.
What is asexual reproduction?
The four phases of mitosis
DNA replication
What is the process in which DNA is duplicated?
DNA is precise, complex information.
How does protein sythesis provide evidence of a Creator?
Yeast is an example of this method of reproduction.
What is budding?
An example of a lobster growing a new pincer is an example of this.
What is regeneration?
Sister chromatids are lined up at the center of the spindle
It is single-stranded, the base uracil replaces thymine, and it contains a different sugar.
How is RNA different than DNA?
Chromosome movement allows for equal distribution of the chromosomes between two new daughter cells.
Why is it important that chromosomes move during mitosis?
This process involves two divisions and produces haploid daughter cells called gametes.
What is meiosis?
What is the difference between meiosis and mitosis?
