What two types of molecules are involved when the codon pairs with its anticodon?
The two types of molecules that are involved when the codon pairs with its anticodon are : 1. mRNA 2. DNA
How the bases that form DNA make pairs?
Each of the chemical molecules preferentially form hydrogen bonds with the corresponding molecule of its pair. So G pairs with C, and A pairs with T.
Assume that a section of double-stranded DNA contains 100 base pairs If 40 of the pairs contain base c how many pairs would contain base a?
60
What is uracil in RNA?
a base containing nitrogen that is found in RNA (but not in DNA) and derived from pyrimidine; pairs with adenine
What base can adenine pair?
In DNA, adenine pairs with Thymine In RNA, adenine pairs with Uracil The code letters are A, T, G, C, which stand for adenine, thymine, guanine, and cytosine. These four chemicals create DNA.
Pairs of atoms that share equal number of electrons?
Molecules covalently bonded.
Based on the Lewis structure the total number of unshared electrons pairs or nonbonding domains in the CO2 molecules is?
CO2 does not have unshared pairs of electrons.
What factors affect the shape of the molecule?
The factors affecting the shape of the molecules are the bonded e and the lone pairs of electrons
What two types of molecules are involved when the codon pairs with its anticodon?
The two types of molecules that are involved when the codon pairs with its anticodon are : 1. mRNA 2. DNA
What do atoms form when they share electric pairs?
molecules
How is VSEPR theory helpful?
Valence shell electron pair theory is useful in predicting the shapes of molecules. All that is done is to count the number of electron pairs around an atom and then work out the shape as the pairs of electrons repel each other. 2 pairs linear 3 pairs trigonal planar 4 pairs tetrahedral etc
Why do you think some molecules have linear molecular structure while others have bent molecular structures?
because having of different number of lone pairs
Do lone pairs affect the shape of diatomic molecules?
yes
How many complete DNA molecules after three rounds of replication?
Each time a cell divides it's 23 PAIRS of chromosomes are divided and then 23 go to each of 2 new cells. Then each new cell with 23 chromosomes then replicates it's chromosomes so it has 23 PAIRs. Just look at a diagram of cell "mitosis". After the first mitosis: 46 pairs and 2 cells, Second round: 4 cells containing 92 PAIRS of DNA total. 3RD ROUND: Eights cells each containing 23 PAIRS of chromosomes: 8 x 23= 184 total chromosomes.
What is the name given to the pairs of valence electrons that do not participate in bonding ina diatomic oxygen molecules?
These pairs of electrons are referred to as lone pairs.
What pairs of molecules form the steps in the DNA molecule?
nitrogenous bases
The two strands of DNA molecules are held together by?
base pairs
