Biology 1
What part of DNA holds the genetic information?
Nitrogenous base
Cell that does not contain a nucleus or any other membrane-bound organelles. EX: Bacteria
Prokaryotic Cell
What is the importance of DNA replication occurring without any mistakes?
No mutations will occur
Why is DNA important?
It gives each cell instructions on how to do its job.
Most cellular respiration takes place in the
Mitochondria
Energy currency of cells
What is Adenosine Triphosphate (ATP)
Which biomolecule carries genetic information?
Nucleic Acid
Define incomplete dominance
mix between the dominant and recessive traits.
What does a virus need in order to reproduce?
A host cell
Give an example a two types of viruses
Lytic: Flu, Common Cold, COVID
Lysogenic: HIV, Herpes, Chicken pox
Which organisms have the most available energy in a food pyramid?
Producers
The legs of crocodiles and mice have similar bone structures and develop in a similar way. What type of structures are the leg bones?
Homologous structures
Distinguish between heredity and genentics.
Hereditiy it the traits passed from parent to offpring, while genetics is the study of traits passed from parent to offspring.
A cell containing a nucleus and other membrane-bound organelles.
Eukaryotic Cell
DNA is located in the what part of the cell?
Nucleus
What do viruses have in common with living cells?
Genetic Information
A change in the sequence of nitrogen bases in a gene is called a
mutation
Define the terms dominant and recessive.
Dominant traits always block out the recessive traits.
What happens in S-phase of the cell cycle?
DNA Replication
What are made up of nucleotides?
four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).
Which symbiotic relationship occurs when both organisms benefit from each other?
Mutualism
Protein is the product of what process?
transcription
Which organelle is DNA usually found in?
nucleus
What is the purpose of cellular respiration?
To create ATP energy from glucose
what was the last strain of covid 19
The Omicron Variant
The delta Variant
