QUESTION 8Which piece of evidence provides the strongest support for the endosymbiosis theory?O All eukaryotes have mitochondrion, but not all have chloroplasts.Genes in chloroplasts and mitochondrion have a high degree of similarity to bacterial genes.O The mitochondria uses a slightly different genetic code than nuclear gene.All of these.

The notion of endosymbiosis is significant because it explains the origins of chloroplasts and…

QUESTION 2 Why do telomeres shorten each time cells divide? O This only occurs in tissues where telomerase is inactive. O The telomerase enzyme clips off a few units of telomere length each generation O They use an RNA template, like Okazaki fragments O They get damaged over time via normal cellular processes
QUESTION 9 Why is a variegated plant considered heteroplasmic? O The plant has mutant and wild-type chloroplast DNAS distributed amongst the cells in different ratios. O The plant has only two types of cells, one with only mutant chloroplast DNAS and one with only wild-type chloroplast DNAS. O All of the plant's cells have mutant and wild-type chloroplast DNAS. O All of the plant's cells have mitochondria and chloroplasts.
Question 1 Choose the definition below that describes a gene. O One compacted DNA molecule O Identical twin sister chromatids Has a centromere and telomeres A segment of DNA molecule that codes for particular characteristic
QUESTION 9 How do the two cells formed by a mitotic cell division compare to each other? O A. The two cells formed by a mitotic cell division have different DNA because of the direction the DNA migrated in Anaphase. O B. The two cells formed by a mitotic cell division are different sizes because of the pinching in during Telophase. OC. The two cells formed by a mitotic.cell division are identical to each other. O D. The two cells formed by a mitotic cell division are given different amounts of different organelles as the cell divides and this is how different kinds of cells are made.

162 Chapter 14 In genetics a single set of chromosomes is symbolized by the letter "n." Any cell that has only one set of chromosomes is termed haploid. Haploid means that the cell has one of each kind of chromosome. The set concept will be used throughout the rest of this lab, so the following questions were designed to aid you in understanding and recognizing sets. Remember that a set is a group of objects related in function and generally used together. 1. Pretend that the fingers of one hand represent chromosomes. (Count your thumb as a finger.) Hold up your hand. ? QUESTION a. How many fingers (chromosomes) do you have on one hand? b. Do you have different kinds of fingers on one hand? c. Do you have more than one of each kind of finger on one hand? set(s) d. Judging by the definition of a set, you have of fingers on one hand. 2. Pretend all the numbers within the circle represent chromosomes. 4 a. How many numbers are there? 2 b. Are there different kinds of numbers? c. Is there…

QUESTION 6 How does meiosis make sure that a baby has the same number of chromosomes as a parent? O A. Each parent mixes the DNA of their parents before putting it in an egg or sperm. O B. Each parent only puts half of their DNA into each egg or sperm so together they make the same number as one adult has. O C. It doesn't. The amount of DNA in a child is always twice the amount as one of its parents because it got DNA from two parents. O D. The number of crossing over events is always an even number.

Question 3 Review genome size, gene number, and gene density. Select the false statement. Number of genes is not correlated to genome size O Genomes of most bacteria and archaea range from 1 to 6 million base pairs (Mb) O Eukaryotic genomes tend to be larger. O Free-living bacteria and archaea have 1,500 to 7,500 genes. O Humans and other mammals have the highest gene density, or number of genes, in a given length of DNA
Item 12 12 of 15 Part A A series of hybrid cell lines was created by somatic human-mouse somatic cell hybridization. Each cell line (numbers 7, 12, 17, 28, and 32) was examined for the presence of human chromosomes and for the ability to produce an enzyme. The fresults shown below were obtained. On the basis of these results, which human chromosome has the gene that encodes the enzyme? Human Chromosomes Present Cell Line 7 4 5 6 7 Enzyme production Yes 1 2 3 8 10 + + 12 Yes 17 Yes 28 No 32 + Yes chromosome 8 chromosome 5 chromosome 1 chromosome 4 chromosome 10 Submit Request Answer Provide Feedback Next
