Answer:
If the progesterone levels are reduced or withdrawn during pregnancy, then the uterus may not be able to carry the baby to term because it would contract more and perastalsis may increase which may cause spotting and miscarriage.
Explanation:
Progesterone is a female sex hormone. It’s produced mainly in the ovaries. It is necessary for the maintenance of pregnancy. Progesterone's main job is to get your uterus ready for pregnancy.After ovulation progesterone helps thicken the lining of the uterus to prepare for a fertilized egg. Along with that it also
necessary for breast development and breastfeeding.
Answer:
The various steps in the transcription and translation process of protein synthesis are described below.
Explanation:
Proteins (made up of amino acids) have an important role in the various functioning process of an organism. Protein synthesis which takes place in the cells of an organism consists of two major processes: transcription (DNA to RNA) and translation (RNA to protein).
Transcription: It is the first process in protein synthesis which occurs in the cell nucleus where a single-stranded messenger RNA (mRNA) is created using a DNA strand and the genetic instructions in DNA are transferred to this mRNA. The steps in transcription are initiation, elongation, and termination. The beginning process known as initiation occurs when an enzyme RNA polymerase binds to a promoter (region of a gene) and the DNA unwinds. One of the DNA strands acts as a template and the enzyme reads the bases in the template DNA strand.
The next step is elongation, where the RNA polymerase builds a strand of mRNA by the addition of nucleotides using complementary base pairs. Here, adenine (A) in the DNA binds to uracil (U) in the RNA. Termination is the last step in which the transcription process ends when the RNA polymerase comes across a termination sequence in the gene. Thus, the completed single-stranded mRNA detaches from DNA.
Translation: It is the second process in protein synthesis which occurs in the ribosome of the cell where the genetic information in mRNA is used to create a protein from amino acids. A triplet of nucleotides is called a codon and they define amino acids. There are 64 possible codons and the codon, AUG acts as the start codon which initiates translation in addition to specifying the amino acid methionine. In the initiation step, the first amino acid in the polypeptide chain is brought by transfer RNAs (tRNAs) to bind to the start codon of mRNA. During elongation, each type of tRNAs in the cytoplasm bound to a specific codon on the mRNA template and adds the corresponding amino acid to the polypeptide chain. Stop codons (UAA, UAG, or UGA) terminate protein synthesis and release the polypeptide.
Answer:
Mid ocean ridge
Explanation:
They are formed under water and there movement is generally up an out. I hope you get it right!
Electron Affinity is not far different from Electronegativity. It’s just that Electronegativity is the impulse of an atom to attract a shared pair of electrons (or electron density) towards itself and is much more often associated with molecules rather than each atom and the values could vary to some degree, although a single value is commonly used for most calculations in inorganic chemistry whilst Electron affinity is a fixed value of an individual atom.
Answer:
The sliding filament theory explains the mechanism of muscle contraction based on muscle proteins that slide past each other to generate movement. ... The sliding filament theory is a widely accepted explanation of the mechanism that underlies muscle contraction.
