Evolution accounts for the unity and diversity of life, and the continuity of life is based on heritable information in the form of DNA. In a short essay (100-150 words), discuss how the fidelity with which DNA is inherited is related to the processes of evolution. (Review the discussion of proofreading and DNA repair in Concept 16.2.)
DNA is responsible for your phenotype, but to what extent? How much, if at all, do environmental factors play a role? Can you find examples (remember keep your sources academic)?
Explain to a friend the characteristics a molecule must have to function as genetic material and then explain the important features of the structure of DNA that are consistent with its role as the chemical basis of heredity.

- we have focused on DNA, the molecule that stores genetic information in all living things. In particular, we discussed its structure and delved into how weanalyze this molecule. Based on your knowledge of these topics,answer several fundamental questions: Question: How were we able to determine that DNA, and not someother molecule, serves as the genetic material in bacteria,bacteriophages, and eukaryotes?arrow_forwardEach cell of the human body contains 46 chromosomes. How many DNA molecules does this statement represent? How many different types of DNA molecules does it represent?arrow_forward50 words essay on how important to have an adequate knowledge of biochemistry in understanding geneticsarrow_forward
- DNA sequences can act as "tape measures of evolution". Scientists analyzing the human genome sequence were surprised to find that some regions of the human genome that are most highly conserved (similar to comparable regions in other species) don't code for proteins at all. Given what you've learned about "genes" speculate on reasons why this might be so.arrow_forwardComplete each of the following events in their proper order. In the first event you must transcribe the proper RNA sequence from the DNA sequence provided. In the next event, you must translate the RNA strand that you have just created and use it to create the proper string of AMINO ACIDS and, eventually, the proper PROTEIN. When your protein is completed, the final event is to match your protein with it's proper trait.arrow_forwardIs it possible to discern among human chromosomes at the DNA sequence level? 1. Yes 2. Noarrow_forward
- 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_forwardEVOLUTION LINK DNA technology, such as the production of transgenic animals, is possible only because widely different organisms have essentially identical genetic systems (DNA RNA protein). What is the evolutionary significance of the universality of genetic systems in organisms as diverse as bacteria and pigs?arrow_forwardComparing your plant (banana) and animal (human) samples, which has more DNA? Take note that DNA is carried on chromosomes, relate your explanation with how many chromosomes each sample carries.arrow_forward
- Is it possible for their to be a mutation where an individual has incomplete or missing sets of chromosomes? or Would that simply result in the loss of life? I would say an easier way to describe a genome is by calling it either a blueprint of DNA or referring it as one full set of genetic information.arrow_forwardWhich statement best describes a genomic library? an initial amount of DNA can be multiplied into millions of copies a large collection of bacteria that are engineered to contain fragments of an organism's complete genome a collection of DNA sequences are arranged on a microscopic grid many small pieces of circular, double-stranded DNA that replicate independently of chromosomes contained in a nucleusarrow_forwardThe formation of a double-stranded structure must obey the rule that adenine hydrogen bonds to thymine (or uracil) and cytosine hydrogen bonds to guanine. Based on your understanding of genetics (from this course or a general biology course), discuss reasons why complementarity is an important feature of DNA and RNA structure and function.arrow_forward
