Mitosis: Asexual reproduction, Four daughter cells, The chromosome's double in number, 46. Two cell divisions, They are identical

Meiosis: Sexual reproduction, Four daughter cells, The chromatid count never changes, Two divisions, They are genetically different from the parent.

Figure 1 Meiosis and mitosis are both preceded by one round of DNA replication; however, meiosis includes two nuclear divisions. The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell.

Professional gardeners often soak seeds in hydrogen peroxide before planting them. Why?
prisoha [69]

Answer:

Professional gardeners often soak seeds in hydrogen peroxide before planting them in order to increase the germination percentage or to reduce germination failure. When the seeds are soaked in hydrogen peroxide, the seed coat becomes soft and enzymes present in the seed becomes active. Due to soaking of seeds, the seed takes less time to germinate. So that's why gardeners uses this method.

Which of the following mutations would cause the most dramatic change in the polypeptide product of a certain gene?
Mnenie [13.5K]
The type of mutation that would cause the most dramatic change in the polypeptide or protein product of a certain gene is the base-pair deletion.  A deletion is a mutation in which the part or the base is lost during the process of replication. Any number of nucleotides can be deleted from a single base to an entire piece of chromosome.

Contrast the genetic content and the origin of sister versus nonsister chromatids during their earliest appearance in prophase I
Bogdan [553]

Answer:

<u>Sister chromatids are identical  forms of chromatids  of a chromosomes. They are mostly  formed by semi-conservative replication of DNA molecule of a single  chromosome.Thus they  are  like  </u><u>'photocopies' </u><u> of  original parent  chromosomes; joined together at the Centromere</u>.

They are exactly similar in all ramification; with the same gene and allele compositions..

<u>However; slight differences  arise between the two identical sisters due to  </u><u>mutation</u><u> from</u><u> errors </u><u>at replication;and also in  the  length of telomere repeats.</u>

Non-sister chromatids are dissimilar forms of  chromatids of a chromosomes formed  when each half of  a chromosome  at fertilisation from separate   haploid sex-cells, of each parent. fused.They contain different genetic composition;because  they are not on the same homologous chromosomes.Therefore crossing -over ensure variation.

<u>However, they are genetically  similar in composition; if they  are contained in homologous chromosomes</u>. This is because Synapsis of bivalent of these chromosomes allow genetic material to be shared by  chromosomal crossing-over between the non-sister chromatids  on the chromosomes ; therefore identical genetic characteristics are shared .
