When comparing evolutionary similarities between different genes within a gene family, it is usually more straightforward to compare genes by using the protein sequences of gene products rather than DNA sequences of the genes themselves. Explain why this is the case. (Write 5 points)
The Selfish Gene is a radical theory that argues that all living creatures are essentially vehicles for their genes- hence, we all are a “survival machine" for our genes.
In the light of what you have learned about the molecular structure and function of the gene, is this perspective still relevant? Cite specific biological phenomena to prove your point.
Q1: If all genes are composed of just four nucleotides, how can different genes carry different types of information? Q2: Would you expect to see more variation in the sequence of DNA bases between two members of the same species (such as humans) or between two individuals of different species (for example, humans and chickens)? Explain your reasoning. Q3: Do different alleles of a gene have the same DNA sequence or different DNA sequences?

- When the human genome sequence was finally completed, scientists were surprised to discover that the genome contains far fewer genes than expected. How many genes are present in the human genome? Scientists have also found that there are many more different kinds of proteins in human cells than there are different genes in the genome. How can this be explained?arrow_forwardAssumptions: -There are approximately 3,000,000,000 base paris in the mammalian genome (genes constitute only a portion only a portion of this total. -There are approximately 10,000 genes in the mammalian genome. - A single gene averages 10,000 base pairs in size. -Only 1 out of 3 mutation that occur in gene result in a chnage to the protein structure. In the mammalian genome: How many total base-pairs are in all the mammalian genes? what proportion (%) of the total genome does this represent? What is the probability that a random mutation will occur in any given gene? What is the probability mutation will change the structure of a protein?arrow_forwardHemoglobin from the Galapagos tortoise is 64% identical to that from human beings. In contrast, a protein called histone H2B is 98% identical in these two organisms. What level of identity would you expect for histone H2B for gorillas compared with human beings? 0% 32% 64% 100% Would histone H2B be as useful a molecular clock as hemoglobin? No, because its sequence changes too quickly. Yes, because its sequence changes slowly enough. No, because its sequence changes too slowly. Yes, because its sequence changes quickly enough.arrow_forward
