BIOS 251 Exam 2 Questions and Answers |Latest 2023/2024 - Chamberlain Cell division in which the nucleus divides into nuclei containing the same number of chromosomes - Mitosis The resting phase of mitosis. Cell grows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases - Interphase Cells that have left the cycle and cease dividing for a long time (or permanently) - G Zero (G0) Phase The first gap, or growth phase, of the cell cycle, consisting of th...

Uncorrected mistake during meiosis will lead to: - ANSWER production of gametes with mutated genes What molecule holds instructions for the synthesis of protein and copies itself for the next generation of cells: - ANSWER DNA DNA's sugar-phosphate backbones are joined with - ANSWER covalent bonds Strands of DNA are joined by - ANSWER hydrogen bonds If you were watching a cell undergoing a doubling of the dna in its nucleus, you would be observing - ANSWER replication

What does the process of meiosis result in? - -A reduction in the chromosome number Why is crossing-over one of the most important events in meiosis? - -It produces new combinations of alleles on chromosomes. Which mode of inheritance describes a condition that exclusively affects males? - -Y-linked A man with disease X and a woman without disease X have five sons and five daughters. All of their daughters inherit the disease, while none of the sons do.Which mode of inheritance is described...

Cyclin correct answer: Cellular protein that play an important role in regulating the cell cycle. Genome correct answer: Consists of the complete genetic sequence of a cell. Somatic Cells correct answer: Non-reproductive cells. Have two sets up chromosomes making it a 'diploid' cell. Gametes correct answer: Reproducing cells (egg and sperm) Have only a single set of chromosomes making it a 'haploid' cell. What are the two main phases of the cell cycle? correct answer: 1. I...

NSG 530 STUDY GUIDE Patho Quiz 1 Graded A+ . STUDY GUIDE FOR QUIZ #1 Advanced Pathophysiology Study the process of meiosis – specifically what occurs when homologous chromosomes fail to separate Human cell can be categorized into gametes (Sperm & egg cells) and somatic cells, which include all cells other than gametes. Each somatic cell nucleus has 46 chromosomes in 23 pairs. These are diploid cells, and the individual’s father and mother each donate on chromosome per pair. New soma...

Blending Inheritance Theory - ANSWER-Theory that the traits of parents were blended together to result in an equal distribution of traits in their offspring Mendel's First Theory - ANSWER-The principle of segregation (First Law): The two members of a gene pair (alleles) segregate (separate) from each other in the formation of gametes Factors - ANSWER-Genes, separated during gametogenesis Allele - ANSWER-An alternative form of a gene. Genotype - ANSWER-An organism's genetic makeup, ...

Mitosis part of eukaryotic cell division during which the cell nucleus divides characteristics: 1. development of an individual, composed of some 50 trillion cells, from a one-celled fertilized egg 2. growth of all tissues and organs after birth 3. replacement of cells that die 4. repair of damaged tissues. Prophase Chromosomes become visable and releases into the cytosol, nuclear envelop dissolves, spindle fibers form, centrioles lie at each pole of cell, and spindle fibers then tug t...

Not very many proteins in the eukaryotic cytoplasmic membrane. Where did they go? - Answer-They are still in the membrane and they are still busy, but most of the proteins went to the mitochondrial membrane in eukaryotes. Cellulose and Chitin - Answer-Use specific b-1,4-glycosidic bonds between sugars provides strength and rigidity. In algae Fungi - Cell Wall - Answer-You have a NAG in chitin for cell walls in fungi. The cell wall is all NAGs Cytoskeleton Function - Answer-Involved in intr...
