Answer:
A. UUA AAG GCU UAC CCU
Explanation:
Transcription is the first process of Gene expression, which involves the synthesizing of a mRNA molecule from a DNA strand. This process (transcription) which is carried out or catalyzed by an enzyme called RNA polymerase, uses the complementary base pairing rule to synthesize nucleotides.
The complementary base pairing rule as proposed by Chargaff states that Adenine base (A) should bond with Thymine base (T). Likewise for Guanine (G) and Cytosine (C). Hence, in a DNA strand with sequence: AAT TTC CGA ATG GGA, the following RNA will result:
UUA AAG GCU UAC CCU.
Note that, Uracil base replaced Thymine base in the mRNA molecule.
Since; A-U and G-C
AAT TTC CGA ATG GGA ---------- DNA
UUA AAG GCU UAC CCU --------- RNA
Answer:
Greenhouse effect is a natural process that warms up earth's atmosphere. Sun radiations when hit the ground are absorbed and some reflected back to the atmosphere and absorb by the greenhouse gases. ... But due to excessive human activities, greenhouse effect is high and making the earth hotter
Explanation:
Answer:
Municipal solid waste (MSW), is the type of waste that contain items related to everyday use.
Different countries have different ways to manage their Municipal solid waste (MSW), some of the techniques used by developed and under-developed countries are as following:
Developed Countries: Example of developed countries are Norway, Australia and USA et-cetra. Disposal methods used are:
- Composting - decomposing organic solid wastes into humus.
- Sorting - In this method garbage is sorted or dumped in bins on the basis of their type such as paper, colored glass and white glass et-cetra.
Both: Disposal methods used by both the countries are:
- Incineration - disposal of waste through burning
- Landfills - MSW is placed in landfills apart from human contacts.
Under-developed Countries: Example of under-Developed countries are India, Afghanistan and Algeria et-cetra. Disposal methods used are:
- Open uncontrolled dumping - throwing waste in open
- Waste picking - waste pickers pick recyclable waste.
Hence, there are some common and some different ways to dispose MSW in developed and under-developed countries.
The above statement is very true.
The inguinal hernia results from abnormal enlargement of the opening of the inguinal canal through which vessels, spermatic cord and nerves of male reproductive system pass (in males only). Hernias are protrusion of visceral through abdominal wall. They may be congenital or acquired ; Acquired occurs when a natural weakness is further aggravated by either a strain or a direct blow.
The second messenger camp is synthesized by the enzyme adenylyl cyclase.
