Fine spines (s), smooth fruit (tu), and uniform fruit color (u) are three recessive traits in cucumbers, the genes for which are linked on the same chromosome. A cucumber plant heterozygous for all three traits is used in a testcross, and the following progeny are produced by this testcross: Tu Tu 70 Tu 21 tu 4 tu 82 tu 21 Tu 13 tu 17 Total 230

Q: Why is it useful to survey expression of the entire genomeunder particular conditions?

A: Expression of the entire genome involves studying expression and the variation in expression in a…

Q: Explain how a gene in a multicellular organism may produce differentproducts in different types of…

A: Genes code for the amino acid sequence of polypeptides.

Q: Describe the difference in the effects of a mutation in a gap gene versus one in a pair-rule gene.

A: The genes consist of hereditary information in the deoxyribonucleic acid (DNA) sequences and is…

Q: Explain how the Sxl promoter “counts” the number of Xchromosomes in Drosophila.

A: In Drosophila, male flies have only one X chromosome and female flies have two XX chromosomes.

Q: Describe the functions of the RAG1 and RAG2 and NHEJ proteins.

A: Regulatory protein (or gene-regulatory protein) is any protein that controls the transcription.…

Genome annotation

The technique of linking biological information to genome sequences is termed genome annotation. Gene annotation is the method of identifying gene locations and coding sections. It helps us understand what these genes are doing in the body through establishing structural characteristics and linking them to the actions of various proteins.
