Gene Expression and Gene Regulation Quick Check 5 of 55 of 5 Items Question Hox genes are regulatory genes in multicellular animals that code for transcription factors that determine the basic body plan in a developing embryo. They act as switches that turn other genes on and off. Scientists have found that a mutation in a fruit fly hox gene produces flies with legs instead of antennae sticking out of their heads. Another hox gene mutation results in fruit flies with two pairs of wings instead of one pair. Hox genes affect body plans by controlling the expression of many other genes. Many multicellular animals have the same hox genes. Which statement is evidence for this claim? (1 point) Responses The body plans of complex animals typically have a large number of mutations. The body plans of complex animals typically have a large number of mutations. The body plans of complex animals are very similar to one another. The body plans of complex animals are very similar to one another. The body plans of complex animals change over generations. The body plans of complex animals change over generations. There is a wide variety of body plans in complex animals. There is a wide variety of body plans in complex animals. Skip to navigation
The statement "The body plans of complex animals are very similar to one another" is evidence for the claim that many multicellular animals have the same hox genes.
the answers are The body plans of complex animals typically have a large number of mutations. The body plans of complex animals typically have a large number of mutations. The body plans of complex animals are very similar to one another. The body plans of complex animals are very similar to one another. The body plans of complex animals change over generations. The body plans of complex animals change over generations. There is a wide variety of body plans in complex animals.
I apologize for the confusion. The correct answer is "The body plans of complex animals are very similar to one another." This evidence suggests that the presence of similar hox genes in multiple organisms contributes to the conservation of body plans across different species of complex animals.
To determine the step in which the removal of introns occurs in eukaryotic cells, we need to understand the process of gene expression and RNA processing.
In eukaryotic cells, gene expression involves several steps: transcription, RNA processing, and translation. RNA processing is the step where pre-messenger RNA (pre-mRNA) molecules undergo modifications before becoming mature mRNA.
During RNA processing, introns (non-coding regions) are removed from the pre-mRNA, and the remaining coding regions called exons are spliced together to form the mature mRNA. This process is known as splicing.
Hence, the removal of sections of RNA, called introns, occurs during the RNA processing step in eukaryotic cells.
Therefore, the correct answer is:
RNA processing.
