Biology

podryga [215]3 years ago
7 0

Answer:

Answer is E.

Explanation:

Chromosomal inversion is a situation involving the segment of a chromosome where it is turned upside down and reinserted back into the chromosome. This usually occurs because of a breakage and rearrangement occurring within a single chromosome.

It is of a two types, these are

* Paracentric chromosomal inversion - a type where a segment not including the centromere is snipped out, inverted, and inserted back to its location on chromosome.

* Pericentric chromosomal inversion - is a type where a segment including the centromere is snipped out, inverted, and inserted back to its original location on chromosome.

Which two examples may be converted into fossil fuel after being buried under pressure for a long period of time
Romashka-Z-Leto [24]
I would say that two products of the earth are coal and petroleum and when they are burned say in a car or a power generating facility they can be converted to fossil fuels.The burning of these fossil fuels are causing too much greenhouse gases and making the earth's temperature rise and resulting in more extreme weather so fossil fuels need to be phased out so the earth will remain inhabitable for humans.

Humans have 46 chromosomes in each somatic cell. a. How many chromosomes does a child receive from its father? b. How many autos
GarryVolchara [31]

Answer:

Explanation:

<u>a. How many chromosomes does a child receive from its father?</u>

Every person receives half of their chromosomes from their father and half from their mother. For that reason, if humans have 46 chromosomes in each somatic cell, 23 of them come from the father.

<u> b. How many autosomes and how many sex chromosomes are present in each somatic cell? </u>

Each somatic cell has 46 chromosomes in total; of which 22 pairs are autosomes and 1 pair are sex chromosomes. Therefore, 44 chromosomes are autosomes and 2 chromosomes are sex chromosomes (the X and/or Y chromosomes).

<u>c. How many chromosomes are present in a human ovum? </u>

The human gametes (ovum in women and sperm cell in men) have half of a somatic cell's genetic material, so that when they combine in a zygote to create their child, they form an initial cell with 46 chromosomes in total. The ovum therefore has 23 chromosomes: 22 autosomes and 1 sex chromosome.

<u>d. How many sex chromosomes are present in a human ovum?</u>

As I mentioned in the previous question, a human ovum has 1 sex chromosome. That way, when it combines with a sperm cell, which also has 1 sex chromosome, they form a zygote with <u>a pair</u> of sex chromosomes (one that comes from the mother and one from the father).

What is the effect of Dideoxycytidine on the replication of viral DNA.
MariettaO [177]

Answer:

Several 2',3'-dideoxy-3'-thiapyrimidine nucleosides were studied for their ability to inhibit hepatitis B virus (HBV) DNA replication in a HBV-transfected cell line (2.2.15). 2',3'-Dideoxy-3'-thiacytidine (SddC) and 5-fluoro-2',3'-dideoxy-3'-thiacytidine(5-FSddC) were found to be the most potent anti-HBV compounds of those examined. Both compounds resulted in nearly complete cessation of viral DNA replication at 0.5 microM, as monitored by the absence of both intracellular episomal and secreted viral DNAs. The HBV-specific RNAs were not reduced at concentrations that completely blocked HBV DNA replication, suggesting that the inhibitory target is HBV DNA synthesis. The antiviral action of SddC and 5-FSddC was reversible. The concentration of SddC and 5-FSddC required to inhibit 50% of 4-day cell growth in culture was 37 microM and more than 200 microM, respectively. Unlike 2',3'-dideoxycytidine, these two compounds do not affect mitochondrial DNA synthesis in cells at concentrations lower than that required to inhibit cell growth. In view of the potent and selective antiviral activity, both SddC and 5-FSddC should be further evaluated for the treatment of human HBV infection.
