Question

Spliceosomes: The environment influence expression of a genotype. Shown below are the complementation test results involving 4 independently isolated lethal mutants in a bacteriophage. Complementation was assayed by simultaneouly Infecting bacteria with two phage strains, each with a different mutation, neither of which could alone lyse tho cells. In the table below, a "+" indicates the strains complemented each other and therefore lysed open the bacteria. A "0" indicates no complementation and therefore no cell lysis occurred. Which mutants are in the same gene? How many genes are there? DNA ligase:

Explanation / Answer

21. b. contain RNA and protein

Spliceosomes are present in eukaryotic nucleus and they are composed of small nuclear RNA (snRNA) and proteins.
