Define heredity
Heredity is the passage of genetic instructions from one generation to the next. It is the passing of genetic instructions from parents to offspring.
100
What is the meaning of prokaryotic?
Prokaryotes have no nucleus. prokaryotic organisms are single celled organisms.
100
What is the main form of reproduction in eukaryotic organisms?
Sexual reproduction
200
What is the term for organisms that are exactly the same?
Uniform
200
What are the weaknesses of sexual reproduction?
Time consuming, you have to find a partner. Takes a lot of energy
200
What are genes?
Sections of DNA that code for a specific trait.
200
Do prokaryotic cells have membrane bound organelles?
No
200
How is the DNA stored in a eukaryotic cell?
the DNA is stored in the nucleus.
300
What are the advantaged of asexual reproduction?
Quick, easy, no partner needed
300
What are the advantages of sexual reproduction?
Genetic diversity=unique combinations of genes. Organisms are more likely to survive since they are not all prone to the same illnesses.
300
What are chromosomes?
Large amounts of DNA packaged together.
300
How do prokaryotic cells reproduce?
By binary fission. The DNA replicates and then the cell splits into two identical daughter cells.
300
How many chromosomes do human cells contain?
46
400
What are the disadvantages of asexual reproduction?
No genetic diversity, all organisms are exactly the same and are prone to the same illnesses.
400
Define reproduction
The biological process by which new organisms are created.
400
What are alleles?
Alleles are a pair of genes that code for a specific trait. You get on from your mom and one from your dad.
400
Do prokaryotic cells have chromosomes?
Yes. They have a single circular chromosome.
400
What are alleles?
Alleles are a pair of genes that determine a specific trait. You get one from mom and one from dad.
500
What are some forms of asexual reproduction?
Budding, fragmentation, vegetative propagation, binary fission
500
Sexual reproduction occurs in what type of organisms?
Eukaryotic
500
Contrast the way DNA is stored in a prokaryotic cell vs. a eukaryotic cell.
In a prokaryotic cell the DNA floats freely in the cytoplasm. In a eukaryotic cell, the DNA is stored in the nucleus.
500
Which two kingdoms are prokaryotic?
Bacteria and Archae
500
What does DNA stand for?
DNA stands for deoxyribonucleic acid.
