Students have asked these similar questions
In Eukaryotes the following are areas of the gene that contain amino acid sequences information
A) Exon’s
B) Introns
C) Activators
D) Promoters
A gene contains the sequence CGCATACGGTAC that results in the amino acid sequence arg-ile-arg-
tyr. A mutation in this gene has a G inserted after the second C in the strand.
How will this mutation affect the phenotype?
A:This will affect the phenotype because although most of the protein will be identical, the first amino
acid will be different.
B:This will not affect the phenotype because only the second amino acid is different from the original
protein.
C:This will not affect the phenotype because the protein will be identical to the original protein.
D:This will affect the phenotvpe because all of the amino acids after the first one will be different from
he original protein.
What is a gene? Provide at least two different definitions and explain.

This process of horizontal gene transfer often results in the formation of enzymes in the host organism that assist in metabolic pathways. Which of the following is the most likely explanation for why bacterial genes are able to successfully transfer genes that produce enzymes in eukaryotic cells? A - Bacteria and Eukarya have similar mechanisms for the formation and use of enzymes in metabolic processes. B - Bacteria and Eukarya use the same enzymes in all of their metabolic processes so the genes are interchangeable. C - Bacteria and Eukarya share similar reproductive mechanisms so the cells reproduce without recognizing foreign DNA. D - Bacteria and Eukarya have the same mechanism for replicating DNA so genes can easily be transferred between the two types of cells.arrow_forward
