Chapter 21: Q1CC (page 440)

Would you expect the genome of the macaque (a monkey) to be more like that of a mouse or that of a human? Explain.

Short Answer

Expert verified

Primates, such as humans and macaques, would have genomes that are more similar than that of mice and macaques. Before the human and macaque lineages diverged, a mouse lineage broke from the primate lineage. That is why monkeys and humans have more similar genomes.

Step by step solution

01

Primates

Primates possess distinguishing traits such as a skull, teeth, and limbs that set them apart from other animals.There are around 300 species in this group, including apes, monkeys, and humans.After bats and rodents, they are the third most common group of mammals.

02

Genome

Genomes contain all of the genetic information of an organism. Each cell in the body contains a specific set of genes that are encoded as DNA or RNA sequences. It is the whole set of an organism's genes, including non-coding sequences. A human genome contains all of the information required to construct them.

03

Lineage

The lineage of two species has diverged as a result of evolution, and many species that were once related have split apart and evolved into new ones. Monkey and mouse genomes are far less similar than the monkey and human genomes, despite the fact that they share comparable DNA.

DNA sequences called homeoboxes help homeotic genes in animals direct development. Given that they are common to flies and mice, explain why these animals are so different.

Describe three examples of errors in cellular processes that lead to DNA duplications.

Insects have three thoracic (trunk) segments. While researchers have found insect fossils with pairs of wings on all three segments, modern insects have wings or related structures on only the second and third segment. It turns out that in modern insects, Hox gene products act to inhibit wing formation on the first segment. The treehopper insect (above) is somewhat of an exception. In addition to having wings on its second segment, the treehopper鈥檚 first segment has an ornate helmet that resembles a set of thorns, which a recent study has found to be a modified, fused pair of 鈥渨ings.鈥� The thorn-like structure helps to camouflage the treehopper in tree branches, thus reducing its risk of predation. Explain how changes in gene regulation could have led to the evolution of such a structure

The scientists mapping the SNPs in the human genome noticed that groups of SNPs tended to be inherited together, in blocks known as haplotypes, ranging in length from 5,000 to 200,000 base pairs. There are as few as four or five commonly occurring combinations of SNPs per haplotype. Integrating what you鈥檝e learned throughout this chapter and this unit, propose an explanation for this observation.

WHAT IF? There are three times as many Alu elements in the human genome as in the chimpanzee genome. How do you think these extra Alu elements arose in the human genome? Propose a role they might have played in the divergence of these two species.
