Haploid cell with half number of chromosomes as parent cell. Result of meiosis - sperm (male) and egg (female)

Biology
1 answer:
IgorC [24]3 years ago
8 0

Answer:

The correct answer is - true.

Explanation:

In the meiosis cell division, there are four cells present with n number of chromosomes which means these cells generated from by the meiosis have a half number of the chromosome as their parents. This is the reason this type of cell division is known as a reduction division.

These cells that are produced are sex cells or reproductive cell sperm in male and egg in female all have n number of chromosome number as they have to fuse to form a zygote.

All of the following are differences in transcription, RNA processing, and translation between prokaryotes and eukaryotes except
Mazyrski [523]

Answer:

the mRNA goes through extensive modifications such as addition of a poly tail and a 5' cap in eukaryotes but not in prokaryotes.

Differences:

- the promoters in prokaryotes have a -35 and -10 box while in eukaryotes they are variable but have a TATA box from  

- the transcription initiation site there is a single RNA polymerase in prokaryotes while eukaryotes have multiple RNA polymerases

- the sigma factor associates with the promoter region in prokaryotes but in eukaryotes there are many basal transcription factors

Explanation:

Ribosomal and transfer RNAs are processed both in prokaryotic and eukaryotic organisms. However, mRNA is only processed in eukaryotes. In eukaryotic cells, mRNA processing involves:

1. Capping at the 5' end. This process has several functions including regulation of nuclear export, prevention of eukaryotic mRNA degradation and promotion of translation.

2. Splicing in order to remove introns and conserve coding exons. Splicing helps to increase the diversity of the eukaryotic mRNAs (and therefore eukaryotic proteins)

3. Polyadenylation by the addition of a poly(A) tail at the 3' end. The poly(A) tail makes the eukaryotic mRNA molecule more stable and also prevents its degradation by exonucleases.

You have a population in hardy-weinberg equilibrium for the m and n alleles. These alleles are codominant. The allele frequency
pishuonlain [190]

You have a population in hardy-Weinberg equilibrium for the m and n alleles. These alleles are codominant.  Allele frequency of m is 0. 4. 0.48 is the frequency of heterozygotes in the population.

An allele frequency has been computed by dividing the total quantity of copies of each of the alleles at that specific genetic location in the population by the number of points of time the allele of interest has been observed in a population.

The frequency of each genotype is typically calculated by dividing the population's total count of individuals by the number of people who have that genotype.

Varvara68 [4.7K]

C. perfringens is found greatly in the environment in soil, rotting greenery and marine sediment, as well as in the intestinal tract of creatures. The bacteria can create endospores, apt of surviving adverse conditions for long periods of time.

<h3>What type of food poisoning is Clostridium perfringens?</h3>

Clostridium perfringens food poisoning is critical gastroenteritis induced by ingestion of contaminated food. Signs are watery diarrhea and abdominal cramps. Diagnosis is by identifying C. perfringens in infected food or in stool.

Thus, Clostridium perfringens food poisoning is critical gastroenteritis caused by ingestion of contaminated food.
