Transcription from DNA<span> to mRNA occurs in the ___ of the eukaryotes. nucleus. Translation. a particular segment of </span>DNA<span> is copied </span>into RNA<span> by the enzyme </span>RNA<span> polymerase. Each tRNA binds to a specific sequence of 3 bases </span>called a<span> codon. </span>
Out of the following given choices;
a. RNA is not able to carry information.
b. RNA is more complex in structure than DNA.
c. RNA would get stuck on the inner surface of the nuclear
membrane.
d. primitive cells would not let RNA molecules across their
membranes.
e. no conditions exist that favor production of both the
sugar and base parts of an RNA monomer
The answer is E. According to evolution, the best adaptable
trait in an environment is highly preserved.
The chemical properties of RNA make large RNA molecules inherently fragile, and
they can easily be broken down into their constituent. Therefore it is unconvincing that was it was used to store critical
genetic information.
Answer:
The endometrium is the mucous layer that lines the uterus internally. Its function is to thicken during the menstrual cycle to allow the embryo to implant and a pregnancy can take place.Two phases of the endometrial cycle are distinguished: the proliferative phase and the secretory phase. The proliferative endometrium occurs due to tissue regeneration on the first day of the menstrual cycle, where, thanks to the production of estrogen in the ovary, cell multiplication occurs, giving rise to the endometrial glands and more blood vessels.
Explanation:
The first phase, known as the follicular phase, begins on the first day of menstrual bleeding and lasts for about two weeks. During this period, one of the ovules - which are the female reproductive cells - grows and matures within an ovary. At the same time, the ovaries produce hormones that promote the development of the lining of the uterus, called the endometrium. The lining of the uterus, the endometrium, thickens in response to estrogen stimulation, that is, over the days, the endometrium becomes thicker and rich in blood vessels, preparing to receive the egg the moment it is expelled from the ovary. When the ovum matures, around day 14 of the cycle, it separates from the ovary - the ovulation process - and slides down the fallopian tube to the uterus.
(1952) to be present on the early Earth and tested the chemical origin of life under those conditions.
Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
