In eukaryotes, extranuclear
inheritance occurs when genetic information is transmitted by
mechanisms other than through nuclear DNA. Chloroplast DNA (cpDNA)
is an example of one mechanism by which extranuclear inheritance
can occur. Select the statements that correctly describe cpDNA.
Homework Answers
a. Chloroplast chromosome contains genes that are involved in photophosphorylation --------> TRUE. (In plants, the photosynthesis takes place in chlorophyll present in chloroplasts).
b. Chloroplast chromosome size and gene content are identical in all organisms ---------> FALSE (Chloroplast chromosome size and gene content is not identical in all organisms, we can use this genetic difference to identify the organism).
c. cpDNA organization is more similar to that of prokaryotes than eukaryotes -----------> TRUE (Chloroplast is more similar to cyanobacteria (prokaryote) than the eukaryotes, which is an important evidence of endosymbiosis).
d. cpDNA is typically inherited from both parents ----------> FALSE (cpDNA is typically inherited from the single parent (maternal side only)).

Part 1. Eukaryotes use at least two distinct mechanisms to control gene expression by altering the structure of chromatin around a particular gene. One of these mechanisms is the covalent modification of histones to switch DNA between an open and closed confirmation. A second mechanism is the covalent modification of DNA (typically on cytosines) by methylation. A. Describe a type of histone modification and explain what effect is has on chromatin, and how that effect is achieved. a. One type...

Bacterial cells, such as E. coli, are surrounded by a fluid plasma membrane and enclosed by a rigid cell wall that protects the cell from damage. You will recall that there is no nuclear envelope in prokaryotic cells, but rather a “nucleoid region” with a single chromosome that is continuous (circular), not linear, as in eukaryotes. All of the genes required for basic survival and reproduction are found in the main chromosome. In addition to the main chromosomes, some DNA...

What are the three functional groups that comprise a nucleotide? What do nucleotides have in common with amino acids or simple sugars? When the structure of DNA was first elucidated, many biologists quickly saw how this structure explained the passage of information from one generation to another. How does the structure of DNA explain generation-to-generation flow of information? In other words, give a brief description of the structure of DNA and tell how this structure allows for replication. Which of...

Is there GxE (gene-by-environment interaction) for the effects of sex in humans? Recall that GxE occurs where the effect of a given environmental change depends on an individual's genotype (for example, where a "better" environment is not equally better for all genotypes), or where the effect of a given genetic change depends on an individual's environment (for example, where a "taller" genotype adds a quantitatively different increment to the individual's expected height, depending on its environmental circumstances). In fact, these...

The following statements apply to concepts and material discussed in Chapter 15; identify which statement is TRUE. Answers: A common ancestor of two species on evolutionary trees can be found at the point where the two branches meet. Humans evolved from Neanderthals about 50,000 years ago. Mitochondrial DNA is not particularly useful when trying to determine the movement pattern of humans historically across the globe. Scientists can estimate when species diverged from a common ancestor by comparing their Karyotypes. We...
