Answer:
The question lacks the illustrative diagram, the diagram has been attached as an image.
The correct answer, according to the picture is A.
Explanation:
All cells undergo division (mitosis or meiosis). Meiosis reduces the chromosomal number of the daughter cells by half. According to the question, The female species of Myrmecia pilosula ant has diploid cells total number of 2 chromosomes.
At the metaphase stage of meiosis I, homologous chromosomes (similar but non-identical chromosomes received from each parent) aligns at the center/equator of the cell called METAPHASE PLATE. This alignment is done when spindle fibres attach to the kinetochores of the chromosomes.
Option A in the diagram depicts this arrangement of homologous chromosomes in the centre of the cell. Note that, each chromosome has replicated to form SISTER chromatids held together at the centromere. These chromosomes will be pulled apart in the next stage (Anaphase).
Option B depicts only one replicated chromosome
Option D depicts separation of sister chromatids (only one chromosome)
Option E depicts separation of sister chromatids of two chromosomes which occurs in the Anaphase of meiosis II
Answer:
Genetic code
Explanation:
Genetic code refers to the set of rules by which the information encoded in the genetic material is translated into the proteins. The genetic code is present on the genes in the form of triplets of nucleotides called codons which specifies the specific amino acid.
The codon system of the genetic code rules allows the 4 different nucleotides to form specific amino acids by the combination of the four different nucleotide in the triplets.
Thus, Genetic code is the correct answer.
Because a Celsius degree is 80% bigger than a Fahrenheit degree.
The microvillus are tiny hair- like membrane that greatly increase the amount of surface area of the cells for better reception. It plays a major role in the tongue that are responsible for sending signals to the brain which then decides the taste of the food particle that is on the tongue.
The long and slender structure gives greater space for absorbing the data and then convert them into signals. Hence the microvillus are the slender projections on the tips of some taste bud cells that extend into the taste pores
Answer:
It exhibits traits and metabolic instructions of the cell.
Explanation:
A DNA strand is a thin long molecule, with an average width of just around two nanometers. The remarkable thinness of the DNA strands allows them to be bundled very tightly fitted inside cells. Once DNA has been replicated adequately during the process of cell division, it is further wrapped together under a mechanism known as supercoiling. A non-condensed DNA is further condensed during supercoiling using a special protein known as a histone. A part of DNA packed around a large cluster of histones is called a nucleosome. Additional condensation leads to a chromosome or the most compact type of DNA that fits into the nucleus. It is also worth noting that this wrapping does not merely align DNA into a cell, but serves other objectives such as protecting DNA, thus ensuring metabolic instructions to the cell.
