Chapter 13, Problem 53P
Summary Introduction

a.

To determine:

The evidence that the entire genome of an ancestral rice plant species is responsible for duplication.

Introduction:

An organism cannot tolerate mutations in a gene. The mutations are essential for the variations in the population of an organism. The process of duplication provides two copies of the gene.

Summary Introduction

b.

To determine:

The reason for the fact that a rice plant is diploid rather than tetraploid if an ancestor rice plant undergoes whole-genome duplication.

Introduction:

The process of evolution depends on the existence of variation in DNA sequences. The variants that enable the organism to survive normally in a particular environment will spread throughout the population.

Summary Introduction

c.

To determine:

The chromosomes of rice that have sequences which are originated in the other ancestral chromosomes.

Introduction:

A chromosome is a thread-like structure of nucleic acids and proteins. The chromosomes are present in the nucleus of living cells. They carry genetic information in the form of genes.

Summary Introduction

d.

To determine:

The evidence that support the genesis of chromosome Os12 involves a translocation event.

Introduction:

Chromosome translocation is a phenomenon which leads to the unusual rearrangement of chromosomes. It involves balanced and unbalanced translocation. It is of two types, first is reciprocal, and the other is Robertsonian translocation.

These are NOT part of any graded assignment. Are there other examples of synapomorphy. What is it called when the traits retained are similar to ancestors?
Please hand draw everying. Thank you! Draw a gram positive bacterial cell below. Your cell should have the following parts, labeled: A coccus shape A capsule The gram positive cell wall should have the peptidoglycan labeled, as well as its component parts (NAM, NAG, and teichoic acid) A cell membrane Fimbriae A nucleoid Ribosomes Inclusions
Draw a gram negative bacterial cell below. Your cell should have the following parts, labeled: A bacillus shape Fimbriae Amphitrichous flagella 2 membranes (outer and inner) The outer membrane should have lipopolysaccharide (LPS) with lipid A and O antigens Periplasmic space The thin peptidoglycan cell wall between the 2 membranes A nucleoid Ribosomes Inclusions
