Answer:
d.They prevent the two parental strands from coming together again.
Explanation:
During the process of DNA replication, the two DNA strands should be separated from each other to serve as a template. To separate the two DNA strands, the helicase enzyme breaks down the hydrogen bonds between the complementary base pairs of the DNA strands. The process uses ATP as a source of energy.
Due to the presence of complementary base pairs, the separated DNA strands have a tendency to reanneal by the formation of hydrogen bonds. To prevent the reannealing of separated DNA strands, single stranded binding proteins bind to them. Binding to single stranded binding proteins to the separated DNA strands does not allow them to reanneal.
This process of dna copying would be mitosis.
The major features of
schizoaffective disorder which clearly delineate it from schizophrenia are marked
symptoms of schizophrenia coupled with major depressive episode or manic
episode. Both schizoaffective disorder and schizophrenia are primary psychotic
disorders.
Answer:
<h2> Replication: DNA into DNA, and RNA primer are required;</h2><h2>Transcription/RNA processing: pre mRNA and then mRNA;</h2><h2>Translation: tRNA, rRNA</h2>
Explanation:
1. During replication, a semi-conservative copy of a DNA molecule is made with the help of various enzymes and RNA primer.
2. Transcription/RNA processing: mRNA
During transcription, the DNA "message" ( in the form of codon) is copied into mRNA.
3. Translation: tRNA, rRNA
During translation, the information carried in the mRNA is translated into protein with the help of molecules of tRNA and rRAN to build a protein on the ribosomes.
