Primers are noncomplementary short strands of nucleotides that are nonspecific True or False
Primers are noncomplementary short strands of nucleotides that are nonspecific
True or False
Homework Answers
FALSE
While a Primer can either be a DNA/RNA - It is inevitable that they need to be complementary to the current strand so that the process of replication can be initiated.

RNA primers on the leading and lagging strands
The diagram below shows a replication bubble with synthesis of the leading and lagging strands on both sides of the bubble. The parental DNA is shown in dark blue,the newly synthesized DNA is light blue, and the RNA primers associated with each strand are red. The origin of replication is indicated by the black dots on theparental strands.Rank the primers in the order they were produced. If two primers were produced at the same time, overlap them

Which of the following statements about DNA replication is FALSE? Primase synthesizes the primers. DNA polymerase is required to add new nucleotides to the growing ends of the DNA strands. DNA ligase joins the small DNA fragments of the lagging strand. Only one strand of the parent DNA serves as a template for a newly synthesized complementary strand.

True or false: in translation, complimentary nucleotides are matched and converted into amino acid sequence. False; in translation codon nucleotides are bound directly to amino acids False; in translation nucleotides are matched by complementarity but amino acid sequence is unrelated True; codons matching anti-codons is the only process where complimentary nucleotides associate True; nucleotides on mRNA and on tRNA are complimentary (the operon and anti-codon) and the tRNA carries a single amino acid

Cells use RNA strands to serve as primers. PCR techniques for amplifying DNA samples use pre-synthesized DNA primers. Explain why RNA primers are not used when replicating DNA fragments in vitro.

if you randomly synthesized RNA strands in vitro using a 1:3 mixture of C:U nucleotides, and then translated those RNA strands in vitro, what proportion of the amino acids in the resulting polypeptide chains will be serine amino acids?
