Cell Cycle Flashcards
Chromosome
A Molecule of DNA
Gene
A particular sequence of nucleotides that codes for a protein
Central dogma uses the gene to make
The enzyme
The enzyme is used in the metabolic pathway. The end products are the
Characteristics
G1, s, and g2 last about
8hrs
M lasts about
One hour
What’s are the steps in the cell cycle
M, G1 , S, G2
What happens in G1
Normal metabolic activities
What happens in G2
All other preparations for division
What happens in S
Synthesis of DNA
Haploid cells have
No chromosome pairs
Diploid cells
Pairs of chromosomes
Triploid cells
Triplets of chromosomes
Octoploid cells
Octets of chromosomes
Is meiosis or mitosis used to make egg and Sperm
Meiosis
Autosomes are
Non sex chromosomes (chromosomes 1-22)
During G1, if no restriction and the cell cycle can’t be stopped… What develops
Cancer
Mitosis takes one parent cell and creates
Two daughter cells
Heterozygous
Different genes
Homozygous
Same gene
Phosodiester bonds
Sugar phosphate bonds.. Strong single covalent bonds. Connects nucleotides
How many genes on each chromosome
1000
Homologous chromosomes
Chromosomes with the same genes at the same loci (places) but they are not identical, may have different alleles
Genotype
The alleles that an individual has for whatever genes are being study
