Answer: The transcription and translation process allows trna and rrna molecules to be used to synthesize wide variety of polypeptides.
Explanation:
DNA molecule is made up of information for coding proteins. This information is passed on the mRNA during a process known as transcription. Transcription is the first of many steps of DNA based gene expression in which a part of the segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase.
Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language. During the process of transcription, a DNA sequence is read by an RNA polymerase, which gives a complementary, antiparallel RNA strand referred to as a primary transcript.
A large diversity among genes is followed by a large amount of various mRNA molecules. However, the ribosomes consist of rRNA, which is included in the process of translation. Translation is the process whereby ribosomes in the cytoplasm or ER synthesize proteins after the process of transcription of DNA to RNA in the cell's nucleus. The overall process is called gene expression.
The smallest of the three types of RNA is tRNA, which has only 75 to 95 nucleotides and has a role in bringing particular amino acids to the growing polypeptide. It can be concluded that mRNA contribute to the diversity of polypeptide molecules due to the fact that it carries an information about their synthesis.
The answer is A. Dark-colored peppered moths on soot-covered tree bark during the Industrial Revolution in England.
Answer:
Her friend
Explanation:
Rebekah is attracted to her friend to whom she is talking about that guy over the lunch. When a person is attracted to someone, he starts sharing his personal situations of life. When a person open up about his personal in front of someone it means he is attracted to that person and feels confidence in telling him. Rebekah is also in the same situation where she feels she is attracted to that guy but actually she is attracted to her friend with whom she is having chat about that guy.
Answer: Arterial thromboembolism
Explanation:
Arterial embolism can be defined as the sudden hinderance of the blood flow to an organ or body part due to the embolus which to the wall of the artery.
This clot can lead to more serious in the future. The arterial embolism occurs due to the consumption of food rich in fat and cholesterol.
It is the main cause of the myocardial infraction and vasoconstriction.
The best way to explain the discrepancy between the normal length of prolactin (199 amino acids) and the length of the polypeptide synthesized in the experiment (227 amino acids) is that in the absence of Signal Recognition Particle (SRP) and the Endoplasmic Reticulum membrane,a prolactin precursor molecule is therefore synthesized.
Prolactin also plays a role in the stimulation of the proliferation of oligodendrocyte precursor cells.
Relating to all, The Signal Recognition Particle plays a crucial role in mediating the transport of secretory and membrane protein to the Endoplasmic Reticulum or plasma membrane.
This can occur both in the prokaryotic or eukaryotic cell.
