The correct answer is:
The principal cause of aneuploidy is chromosome nondisjunction during mitosis or meiosis. Polyploidy in nature can result either from the duplication of euploid chromosome sets from a single species or from the combining of chromosome sets from different species.
Aneuploidy is a phenomenon when there is the presence of an abnormal number of chromosomes in a cell (an extra or missing chromosome). Usually it appears as a result of improper cell division (chromosomes don’t separate) and it can cause many genetic disorders.
Polyploidy refers to a state when there are more than two sets of chromosomes (one from mother one from father). Triploid (three sets of chromosomes) and tetraploid (four sets of chromosomes) chromosomes are examples of polyploidy. This phenomenon is most common in plants.
Answer:
<h2>
merocrine, sebaceous, and apocrine</h2>
Explanation:
Merocrine: merocrine sweat glands are widely distributed across the body surface,
Sebaceous glands are located where hair follicles have existed,
apocrine sweat glands are found only in a few areas like axilla. Apocrine -are restricted to specific areas like the axilla, nipple of the breast, pubic region and around the anus area etc.
No this virus does not follow the Central Dogma of Biology. The Central Dogma refers to the process involved in cellular replication starting from the replication of DNA, followed by transcription of DNA to RNA, and finally translation of RNA to proteins.
Viruses are special because they hijack cells and use the cell's own mechanisms in order for it replicate. Retroviruses are even more special because they go against the unidirectional flow of the Central Dogma. This is done with the use of their <em>reverse transcriptase.</em>
Answer:
an investigator will often use a black light to scan an area for traces of bodily fluids left at the crime scene. if there’s a substance that resembles semen or blood, they will often times apply a spray if it is dry and use a cotton swab to collect it in a vial to test back at the lab for dna evidence.
