- if two heterozygous organisms are crossed what percentage of the offspring are expected to be heterozygous
- what is the scientific name of the organism used by mendel to conduct genetic crosses
- mendel's principle of _______ states that an organism's pair of unit inheritance factors separates from one another during meiosis
- which field of biology was officially founded by Mendel's work?
- which mathematical rule explains the relationship between monohybrid and dihybrid ratios
- what product is the end point of the expression of a gene
- Which phenotypic ratio is observed among the F2 offspring of two heterozygotes?
- which of the following terms is used to describe the genotype of an organism that possesses two alleles of the same type for a certain characteristic?
- if an organism whose genotype if BbDd is used in a test cross, how many diff offspring are expected
- DNA serves as a ______ for the synthesis of an RNA molecule, which then directs the synthesis of a ______ product
- Relationship b/w the DNA base sequence & the linear order of amino acids in the protein products is based on a set of rules known as the
- The genetic code is known as a _______ code because an amino acid can be specified by more than one triplet and ___________ since the reading frame advances 3 nucleotides.
- Mutations that alter sequences near the 5′ end of mRNA result in alterations near the corresponding protein's N-terminal end, whereas mutations that alter the 3′ sequences of mRNA result in alterations in the protein's C-terminal end. What do these findings imply?A. The N- and C-terminal ends of proteins are susceptible to alteration.B. The genetic code is a series of amino acids (the component parts of proteins).C. The order of nucleotides from 5′ to 3′ in mRNA determines the order of amino acids from N- to C-termini.D. The genetic code is universal.
- B DNA can be converted to the Z DNA conformation under certain conditions. In what cellular process is Z DNA believed to have a role?
- Chargaff's rule states that, "in a piece of double-stranded DNA, the amount of ______ equals the amount of thymine and the amount of cytosine equals the amount of ________"
- A sugar such as ribose or deoxyribose, attached to a base but not to a phosphate group is called a _____________
- ~Mendel realized organisms have 2 alleles for every trait~2 alleles are inherited and if the offspring receives a dominate allele from one parent, that dominant allele trait will appear in offspring whereas recessive traits show up in the offspring only if the offspring receives recessive alleles from each parent
