We all know that the DNA molecules are double-stranded in living cells. Please design a Java program to prompt the user to enter a DNA sequence and then find the complement sequence of that DNA sequence, and print out a double-stranded DNA with the complement strand right beneath the original DNA sequence. See the sample output below. Sample output: Here is the starting DNA: ACGGGAGGACGGGAAAATTACTACGGCATTAGC Here is the double-stranded DNA: ACGGGAGGACGGGAAAATTACTACGGCATTAGC TGCCCTCCTGCCCTTTTAATGATGCCGTAATCG

Haploid yeast cells that preferentially repair double-strand breaks by homologous recombination (rather than by non-homologous end joining) are especially sensitive to agents that cause double-strand breaks in DNA. If the breaks occur in the G1 phase of the cell cycle, most cells will die; however, if the breaks occur in the G2 phase, a much higher fraction of cells survive. Why do you suppose this is?

During DNA replication, because each of the double stranded molecules of DNS consists of a single strand of old DNA (parent strand) and a single strand of new DNA (daughter strand), DNA replication is also known as: • A) Origin of replication • B) Replication bubble • C) Semi-conservative replication • D) All of the above

Chromatin is more compacted in prophase than during the G2 phase The key even of Sphase is the segregation of sister chromatids • • The mitotic spindle first appears during anaphase The cell increases in size during metaphase Which of the following correctly represents the order of the phases in the cell cycle? Mitosis, S phase,...

In a test tube, a strand of double-stranded DNA can be separated into two single-stranded DNA molecules by applying energy such as heat. Sequences for two different dsDNA molecules are shown below (dsDNA 1 and dsDNA 2). Which one of these two would require less energy to be separated? Explain your reason. Note: Both dsDNA are 20 base pairs long. The sequence for only one of the strands in each dsDNA are shown dsDNA 1: GCGCACGGACGGCCCGCACC dsDNA 2: TATTAGTATACTAATAAGTT

What is the average radius of a piece of double-stranded DNA in water that has a link length of 5.9 nm and and is 3019228 links long If the two strands of the double-stranded DNA are separated, each chain now has a radius of 530 nm. What is the link length for single-stranded DNA?
