what does helicase do?
it unzips the DNA
what does the DNA polymerase do?
it builds onto the DNA
what does primase do?
Is urcil in RNA
Yes, but not in DNA
No, just DNA
True or false? Changing one base letter on a mRNA codon will always change the amino acids it codes for
False because there so many combinations.
True or False? The mRNA codon UGG is the only codonthat codes for the amino acid trytophan
True.
True or False? the mRNA codon UCU and AGU code for the same amino acid
true
True or False? the mRNA codons GCU and GCC would share the same tRNA anticodon
True, because they are the same amino acids
AUG is generally a start codon. What amino acid that AUG codes for?
methionine
what is genetics?
The branch of biology that studies heredity.
What is heredity?
the passing of traits or characteristics from parent to offspring
Who is Gregor Mendel?
He is the father of genetics, Austrain mask - 1822, one of the first to study patterns of inheritence
What did Mendel study?
Pea plants, detailed records over many generations, predict outcomes using strategies
what is DNA made of?
It is made up of genetic material in a double helix shape
What is DNA significance?
it is in every single one of your cells and determines your genes
What is a chromosome?
It is made of DNA and proteins. Two sister chromosomes connected by the centromere
What is the significance of a chromosome?
Chromosomes allow the large amount of DNA to be compacted. One reason this is significant is in the cell divsion it makes it much easier for the cells to put these units into the new cells
What is a gene?
it is a part in DNA
why is a gene significant?
it is the reason we have traits
