Chromosomes contain genes, regulatory sequences, and non-coding sequences. In prokaryotes, most DNA is made up of genes or regul

atory sequences. However, eukaryotes have a large amount of DNA that does not code for proteins and is not part of regulatory sequences. For example, only about 1.5% or less of human DNA is coding DNA. As a result, eukaryotic genomes are often much larger than would be expected from the number of genes.
Which of the following are noncoding DNA that contribute to the large size of eukaryotic genomes? Select all that apply.

a. Alu elements
b. gene duplications
c. multiple variants of a gene
d. Exons
e. repetitive sequences (simple sequence repeats)

A

D

E

Explanation:

The repetitive sequences on DNA are called satellite DNA or short tandem repeats (STR). They are mainly found in the ends of chromosomes to protect the fringes from shortening during replication cycles.

Alu units are small nucleotide segments – averaging 300 bp long- within the human genome that can transpose. They are thought to be remnants of latent phase of viral or bacterial DNA that infected the human genome in the past. They make up the largest part of non-coding DNA.

Exons, on the other hand, are transcribed with introns on mRNA. The nascent mRNA has to be spliced to removing these noncoding regions to create a mature mRNA that can be translated into proteins.

Entamoeba histolytica can cause keratitis if it is introduced through an abrasion in the conjunctiva
inysia [295]

The given statement was False: A hookworm infestation frequently leads to anemia.

what is entamoeba histolytica ?

The parasitic anaerobic amoebozoan Entamoeba histolytica belongs to the genus Entamoeba. E. histolytica, which mostly infects humans and other primates and causes amoebiasis, is thought to infect between 35 and 50 million individuals globally. It is believed that E. histolytica infections cause more than 55,000 fatalities annually. Prior to the discovery that at least 90% of these illnesses were caused by a second species, E. dispar, it was believed that 10% of the world's population was affected. Although animals like dogs and cats can briefly contract the disease, it is not believed that they significantly contribute to its spread.

Histolysis literally translates to "dissolution and disintegration of biological tissues."

as the given statement was False, "A hookworm infestation commonly results in anaemia."

stroma; thylakoids
thylakoids; stroma
inner membrane; outer membrane
chloroplasts; mitochondria
mitochondria; chloroplasts

thylakoids; stroma

Within the chloroplast, the light reactions take place in the flattened sacs called thylakoids and the Calvin cycle takes place in the thick fluid called the stroma.
