DNA structure, function and replication. DNA is a long molecule that consists of two strands of nucleotides twisted together in a long spiral called a double helix, the base-pairing rules describe which bases pair together in a DNA double helix, work together to produce two identical copies of the original DNA molecule=DNA structure; DNA funcution; RNA; replication; transcription; translation; the two strands are wound round each other to form a double helix. The two strands. Are joined together by hydrogen bonds between the bases, before every cell divison, so that one identical copy can go to each daughter cell =because the two strands of a DNA molcule have complementary base pairs, the nucleotide each can be used as a pattern or template to produce a complementary strand together then form a new DNA double helix, identical to the orginal. The enzyme DNA polymerase then moves along the exposed DNA strand
It reaming most often the process of fossilization.
<h2>Cytokinesis in animal cells</h2>
Explanation:
- The force for cytokinesis is generated by kinesin motors on microtubule bundles that form the contractile ring:This statement is false because cytokinesis in animal cells starts with the assembly of contractile ring,contractile band consists of actin and myosin(microfilaments) which catalyse cleavage furrow formation
- As the contractile ring constricts, its thickness increases to keep a constant volume:This statement is false because thickness remains constant
- The midbody forms from bundles of actin and myosin: This statement is false because contractile ring forms bundles of actin and myosin whereas midbody is formed from microtubules
- Local activation of Ran GTPase triggers the assembly and contraction of the contractile ring:This statement is false because local activation of Rho mediates profilin binding to actin and helps in assembly and contraction of contractile ring
