Answer:
The duplication of DNA is called <u>replication</u>, the copying of DNA to mRNA is called <u>transcription</u>, and the reading of the mRNA by the cell to make a protein is called <u>translation</u>.
Explanation:
Replication is the gradual, repetitive, bidirectional, antiparallel and semi-conservative process; whereby the DNA is duplicated, guaranteeing the availability of a copy of the genome of the stem cell, for each of the daughter cells, in other words, it is the mechanism that allows the DNA to duplicate (that is, synthesize an identical copy of itself).
Transcription is the process by which the genes found in the chromosome DNA are selectively located, recognized and transcribed, producing mRNA, ribosomal (structural) and transfer RNA (adapters).
Messenger RNA is the one that carries the information for protein synthesis, that is, it determines the order in which the amino acids will bind. Translation is the process by which protein synthesis occurs, by decoding or reading the message of (mRNA).
Answer:
Because the F1 plants all had a lowercase a/short plant allele, there was a 25% chance that two plants would contribute it to their offspring and they both did sometimes to make a aa offpsring.
Explanation:
All the F1 plants were heterozygous, so when they were crossed, the resulting genotypic ratio was 1 AA : 2 Aa : 1 aa. As you can see, this is the first time since the parent generation that there is a aa genotype and short plant phenotype, so that's why short plants reappeared.
<span>Homologous chromosomes are chromosomes of equal length, size, and of corresponding genetic material. If, during meiosis, these chromosomes divide improperly, when they are re-combined with the opposite sex's portion, they will combine improperly. The unequal distribution of genetic material in reproduction will eventually create what's call an aneuploid germ cell: this germ cell results in dead zygotes, which leads to a miscarriage or spontaneous abortion in about 25 percent of all conceptions. So we see that it is imperative the genetic material of these chromosomes be exactly where it is supposed to be: so that it can combine perfectly with its compliment.</span>
The difference between RNA and RNA both are not the same but they are different.
Answer:
Bees
Explanation:
Parthenogenesis is a method of asexual reproduction in which an egg cell develops into a new individual without fertilization. Parthenogenesis occurs in insects, amphibians, reptiles, fish, and in some plants. Most of the organisms which reproduces through parthenogenesis, they also reproduce sexually. Parthenogenesis may be occurs by apomixis and by automixis. In apomixis, egg is produced by mitosis and results into diploid clones. In automixis egg is produced by meiosis and the haploid egg develops into diploid new individual by the duplication of chromosomes. Parthenogenesis is an adaptation which allows to reproduce in adverse environmental conditions when sexual reproduction is not possible.
