Return of DNA Segment to Original Form
As the RNA chain grows, the transcribed region of the DNA molecule gets hydrogen bonded to the opposite strand and the two become spirally coiled to assume the original double helical form. When the last ribonucleotide is added, the RNA polymerase and RNA chain are completely r..
Mechanism of DNA Replication
It is a complex process and involves the participation of over a dozen enzymes and other protein factors. The intertwined DNA starts separating from a particular point and this is known as the origin of replicatio..

Do Organisms Create Exact Copies of Themselves?
Do Organisms Create Exact Copies of Themselves? - Organisms look similar because their body designs are similar. If body designs are to be similar, the blue prints for these designs should be similar. Thus, reproduction involves making copies of the blueprints of body design. The chromosomes in the..

Evolution Should not be Equated with Progress
. They ventured down the islands of Indonesia and the Philippines and crossed over to Australia. They finally crossed the Bering land bridge to the Americas. There is a great diversity in human types, with varied forms and features across the planet. We see brown, white, black, skin types, tall Ame..
Prophase
It is the longest stage of the division cycle. It is characterised by significant changes. Chromatids shorten (to about 4% of their original length) and thicken by spiralisation and condensation of DNA Centrioles move to the opposite poles of the cell Short microtubules..
Introduction
The word 'geometry' is derived from the Greek words 'geo' meaning 'earth' and 'metron', meaning 'measuring'. Geometry originated when man felt the need to measure his land. Ancient Egyptians were perhaps the first people to study geometry. Later, the Babylonians studied in a sys..
Summary
>The RNA nucleotides become linked with one another, resulting in the formation of a mRNA molecule. The process is catalysed by the enzyme RNA polymerase. The mRNA subsequently detaches from the DNA template and gets released. It comes out of the nucleus and reaches the cytoplasm. The sep..

Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
all my questions were answered in a very clear way and i learned a new math rules which i did not know this service is very helpful - mike
