Cells 2 Flashcards
A tetrad
Is two sets of sister chromatids one maternal and one paternal
Complex polythene inheritance
Involves multiple gene pairs at the different chromosome locations
An allele that masks the expressions of another is called what
Dominant
ABO blood group inheritance is an example of
Multiple allele inheritance
An allele inherited on the X chromosome in a male will be expressed
True
Three base sequence of MRNa called codon codes for
A specific amino acid
Amino acids undergo what metabolic process in body cells
Protein synthesis
Alleles code for different expression of a trait
Heterozygous
Physical expression of a genetic trait
Phenotype
Two dominant alleles both are expressed
Co dominance
Multiple gene codes for the expression of a single gene trait
Polygene inheritance
Allele whose expression can be masked
Recessive
Paired maternal-parental genes coding for the same trait
Allele
Match DNA to Correct codon
AAG
UUC
Match correct DNA to mRNA codon
CGT
GCA
Match the following DNA to the correct mRNA
TCA
AGU
Example of incomplete dominance
Sickling of red blood cells
3 base sequence of mRNA called a codon codes for
A specific amino acid
If a DNA strand has a nitrogenous base sequence TACGA then the bases on the corresponding mRNA would be..
AUGCA
Homologous chromosomes
Are maternal-paternal pairs of chromosomes
What nucleotide base is unique to RNA
Uracil
Occurs only in the sex cells
Meiosis
Each daughter cell contains exact copies of the parent cell DNA
Mitosis
Produces 2 identical daughter cells each with 46 chromosomes
Mitosis
Division produces 4 non identical daughter cells with 23 chromosomes each
Meiosis
Paired maternal and paternal genes coding for the same trait
Alleles
