- type of RNA that combines with proteins to form ribosomes
- specific region of a gene where RNA polymerase can bind and begin transcription
- any of a group of basic proteins found in chromatin.
- Type of RNA that carries amino acids to the ribosome
- a structural unit of a eukaryotic chromosome, consisting of a length of DNA coiled around a core of histones.
- Is the gender of a baby determined by the mother or the father?
- In pea plants, P codes for purple flowers, and p codes for white flowers. T codes for tall plants, and t codes for short plants. The genes for flower color and plant height are not linked. What are the phenotypic ratios of the offspring of the following crosses: a) PPTt x ppTT; b) PpTT x Pptt; c) PpTt x PpTt
- Explain the difference between codominance and incomplete dominance/intermediate inheritance. Give an example of each (these can be made up).
- In mice, brown fur (B) is dominant to white fur (b). Give the genotypic and phenotypic ratios of a cross between a homozygous dominant individual and a heterozygous individual. Give the genotypic and phenotypic ratios of a cross between two heterozygous individuals.
- Is the following cell haploid or diploid? Draw the cell as it goes through each phase of mitosis, including cytokinesis.
- What's the relationship between DNA, chromosomes, and nucleotides?
- For the above cell, draw the cells that would result if meiosis takes place.
- Draw a section of DNA - be sure to show the nucleotides with their sugar-phosphate backbone, nitrogenous bases, and the bonds that hold everything together.
- During elongation, the polypeptide is removed from the tRNA in the P site and transferred to the amino acid in the A site.
- What holds the sugars in the backbone together
- In the central dogma, the RNA-to-protein step is termed
- The central dogma of gene expression at the molecular level was first proposed by Francis
- The enzymes that catalyze the attachment of amino acids to tRNA molecules are known as which of the following?
- Charged tRNAs are brought to the A site in the ribosome by an elongation factor called
- Most mature eukaryotic mRNAs have a string of nucleotides referred to as a poly-______ tail.
