Answer:
decreasing the number of copies of the polypeptide translated from this mRNA
Explanation:
Polyadenylation refers to the addition of multiple adenosine monophosphates (i.e., a polyA tail) to an RNA molecule, usually a messenger RNA (mRNA). Polyadenylation is catalyzed by an RNA polymerase called poly(A) polymerase (PAP), which adds adenine nucleotides to the mRNA. In eukaryotic cells, polyadenylation is required to produce a mature mRNA which is then used as template for protein synthesis during translation. This posttranscriptional modification (polyadenylation) is known to stabilize the mRNA by preventing its degradation by exoribonucleases, i.e., enzymes that degrade RNA molecules by removing terminal nucleotides from 3' and 5' ends. In consequence, it is expected that a mutation that prevents polyadenylation of a target mRNA decrease the number of copies of the protein translated from this mRNA.
<h2>The Domain and its Changes </h2>
The domain is the range of mandate recognized or constrained by an appropriate leader or authority. In natural taxonomy, a domain is the leading level of taxonomic of bodies in the three-domain system of taxonomy composed by Carl Woese. It has changed over the years by changing the domain name of computers.
Gametes, or sperm and egg cells are both haploid cells, meaning that they have half the amount of chromosomes that regular body cells do, meaning that the sperm cell of this bird would have 32 chromosomes.
Definition
A technique which is used to separate, DNA, RNA or protein pieces from each other under the influence of electric field on the basis of their molecular size is known as gel electrophoresis.
Explanation
This method is very reliable for separation of large size molecule (over 1 million Da). Materials which are required for gel electrophoresis include:
1. TAE stock buffer
2. 1% agrose gel
3. Nucleic acid loading dye
4. Ethidium bromide
Procedure:
First prepare a stock solution of TAE buffer by adding appropriate amount of TAE in distilled water. then prepare 1% agrose by adding 1X TAE, some amount of agrose in water and heating it in microwve oven to mix them will. then pour agrose gel on tray and fix comb in it and keep it untill agrose dry. Then remove comb and pour some quantity of nucleic acid along with loading dye and ethidium bromide in each well. EtBr is used for staining nucleic acid.
When sample is poured in all well also pour reference marker in one well for comparison. now connect it with voltage for 30-35 min. After this take gel and see it under UV. a large number of nucleic acid pieces will be seen on gel under UV. those pieces which have small molecular weight will cover more distance compared to those having larger molecular weight.
Answer:
Body-centered sex
MEN
Explanation:
Sex is defined in various way and portrays different meaning. Some define Sex as always a means of closeness for procreation, or a way of showing love and feeling good(pleasure). To some, it is a sense of duty in fulfilling other partner's wish.
Body-centered sex is a kind of sexual expression where the emphasis is placed on physical pleasure. it focus and draw attention of having sex for pleasure rather than emotion. An old adage once say and i quote "women fall in love with people; men fall in love with genitals." Hence, Body-centered sex is common in MEN
