The Minimal Chromosome To enable it to be transmitted intact from one cell generation to the next, the linear DNA molecule of a

eukaryotic chromosome must have appropriate nucleotide sequences making up three special kinds of regions: origins of replication (at least one), a centromere, and two telomeres. What would happen if such a chromosomal DNA molecule somehow lost: a) all of its origins of replication

We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the _________ group
Alina [70]

Answer: Option B) phosphate; hydroxyl; 3'

We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the phosphate group attached to the 5' carbon atom of the sugar portion of a nucleotide and the hydroxyl group attached to the 3'

carbon atom

Explanation:

For both RNA and DNA, chemical groups such as phosphate (PO3-) attaches to the 5' carbon of the pentose sugar (deoxyribose in DNA, ribose in RNA).

While hydroxyl group (OH) attaches to the 3' carbon atom of the pentose sugar.

Thus, a nucleic acid structure structure reveals a several repeating units of nucleotides where nitrogenous base links to a pentose sugar, who in turns is linked to phosphate group

An example of an epigenetic change is
Oksana_A [137]

Answer:

The correct answer is option d.

Explanation:

An illustration of epigenetic change is a microbe, which can stimulate modifications in the host DNA, causing suppression of defenses or weakening of individual cells. Epigenetic changes modify the physical composition of DNA.  

One of the examples of epigenetic change is DNA methylation. DNA methylation refers to the supplementation of methyl group, which inhibits some of the genes from getting expressed. One of the conditions of DNA methylation is cancer.  

In the majority of cancer, the tumor cells go through global hypomethylation. The tumor suppressed genes seem to turn highly methylated in the conditions of cancer.
