After another enzyme (a DNA helicase) has seperated two orginal strands of DNA, the polymerase moves along the template strand and polymerizes free nucleotides into a new antiparallel strand. ... DNA ligase joins pieces of DNA together, mainly joins Okazaki fragments with the main DNA piece.
Explanation:
the first one and the last one is transverse
Hmm this is a rough explanations but because to be sure cells are made properly and not misfunctioning or going Rouge.
Cancer cells is an example of this, a cell goes rouge and starts doing it's function on it's own but outside of it's brother cells function slightly different turning into a growth or etc. The body thinks it is normal during the check body it's composed of the dna that passes this check.
viruses and other things don't pass this check and things like white blood cella come shut it down.
that's why doctors poison the area they find the cancer. to send white blood cells there to shut the area down not passing the check.
Yes, but only if the chromosomes are paired in the right ways. tetrad development in late prophase.
<h3>How does DNA function? Why does it matter?</h3>
The biological instructions that give each species its distinctiveness are found in a substance known as deoxyribonucleic acid (DNA). Adult organisms reproduce by transmitting their DNA and the genetic information it carries to their progeny.
<h3>What is the purpose of a person's DNA?</h3>
Genes, which are a component of DNA, are the building blocks of all living organisms. DNA's capacity for recurrent self-replication is its most significant property. DNA must be replicated in order to create new cells, convey genetic information from one generation to the next, and act as a code for the RNA (ribonucleic acid) needed to make proteins.
