a) Why was it important to sequence ESTs as well as the human genome? A. Because ESTs contain sequence that is not in the genome B. To identify the location of the exons C. To identify the location of the promoter D. Because ESTs are different than what is in the human genome b) What regions of the genome are missing if only ESTs are sequenced? A. cDNA B. Exons C. mRNA D. 3'UTR E. Introns c) Name a region...

Explain the proposed importance of “junk DNA” in the human genome with respect to the proliferation and horizonal transfer of cis-regulatory elements into new chromosomal locations. Explain, in as much detail as you can, how the mobile DNA, containing, these cis-elements, can influence expression of functional and genes and potentially enable new gene function or activity.

OLU Ucues Assignment 4c. In eukaryotes, genes are composed of exons and introns, with only exons included in the mRNA. Each gene also has its own adjacent promoter, to which the transcribing enzyme RNA polymerase binds. Related genes may be clustered together on the same chromosome as a “gene family." Answer each of the following questions in the answer box of the assignment. You may also write the answers directly into the assignment document and then upload your answers. Number...

1) What is the ultimate goal of the Human Genome Project? A) to rid the human population of genetic disease B) to better understand the genes and regulatory elements of the genome C) to map all the genes in the genome so they can be edited with CRISPR-cas D) to understand all of the proteins generated in a cell 2) ________ alleles are those that are not epistatic over nonallelic genes that influence the same phenotypic characteristic. A) Additive B)...
