Macro Molecules and More!
Macro molecules are divided into these 4 major categories
What are carbohydrates, lipids, proteins, and nucleic acids
Binary fission, mitosis, and meiosis are examples of this?
What are the forms of cell division?
The number of protons and electrons an element contains
What is the atomic number?
The most important inorganic substance is this
What is water?
The study of the chemical basis of heredity is called this
What is molecular genetics?
The process of combining molecules by removing water is called this
What is dehydration syntethsis?
Mitosis has these two main parts
What is mitosis proper (division of nuclear material) and cytokineses (division of the cytoplasm)
This tells you the number of valence electrons for an atom
What is the group number (family number)
Because water can dissolve so much, it is called this
What is the Universal Solvent?
An important enzyme that breaks the hydrogen bonds and allows DNA strands to separate forming a replication fork is called this
What is helicase?
A nitrogen base, phosphate group and a ribose sugar form this piece of usable cell energy
What is ATP?
A cancer causing gene is called this
What is an oncogene?
Chemical bonding between atoms/ elements follows this general pattern.
What is: 1) Metals combine with nonmetals by transferring electrons. 2) Nonmetals combine with nonmetals by forming covalent bonds (sharing valence electrons). 3) Hydrogen combines with C, H, O, N, P, and S by forming covalent bonds (sharing valence electrons)
H2O molecules are attracted to each other through a process known as this
What is adhesion?
These are the Purines.
What are Guanine and Adenine (GA).
This type of bond is found connecting amino acids together. Hydrolysis will break this type of bond.
What are peptide bonds?
Synapsis occurs during this stage of meiosis
What is prophase I?
When Li transfers an electron to F it is said to be this
What is oxidized?
H2O repels non-polar molecules (like oils). Thus oils are said to be
What is hydrophobic?
This scientist found that nucleic acids had 3 basic components in their nucleotide building blocks
Who is Levene?
This is a complex, neutral fat of 3 fatty acids and 1 glycerol.
What is a triglyceride?
This occurs at the end of cell division to split the cell
What is cytokinesis?
An atom that has the same number of protons and electrons is said to be this
What is neutral?
Ionic bonded molecules do this when dissolved in H2O
What is dissociate?
The process in which a ribosome attaches on to the mRNA and starts reading at a "start" codon
What is Initiation?
