RNA sample were composed of 20% adenine, what would be the percentage of guanine?

IF A DOUBLE-STRAND DNA SAMPLE WAS COMPOSED OF 10 PERCENT THYMINE, WHAT WOULD BE THE PERCENTAGE OF GUANINE?

A double-stranded DNA molecule is 1 cm long, and the percentage of adenine is 15%. How many cytosines does this DNA molecule contain?

Name the bases in the pentanucleotide with the sequence G-A-U-C-A. Does this come from RNA or DNA? Explain.

a) What type of bond does helicase break? b) Which of these two types of bonds is stronger? c) Describe why it is necessary for the lagging strand to be made in fragments, called Okazaki fragments.

According to the Watson- Crick model how many polynucleotide chains does a DNA molecule have?

An analysis of the genetic material of an unknown sample showed that it contains 1996 adenine bases, 2131 guanine bases, 1642 uracil bases and 2365 cytosine bases. Which one of the following describes the genetic material of the unknown sample? * Single Stranded DNA Single Stranded RNA Double Stranded DNA Double Stranded RNA Match the statement to the correct molecule. * Cytosine Cytosine Nucleobases Guanine Guanine Base pair

Write the complementary sequence for the following DNA sequence, in order from 3' to 5': 5′−CGATATTGAGCTAAGCTT−3′

One gram of cultured human cells contains about 109 cells and occupies roughly 1 mL. If the average molecular mass of a base pair is 660 daltons and each cell contains 6.4 x 109 bp, what mass of DNA is present in this one-gram sample? If all the DNA molecules in the sample were laid end to end to form a single thread, would it be long enough to reach from the Earth to the Moon (385,000 kilometers)?

One gram of cultured human cells contains about 10^9 cells and occupies roughly 1 mL. if the average molecular mass of a base is 660 daltons and each cell contains 6,4 *10^9 bp, what mass of DNA is present in this one-gram sample? If all the DNA molecules in the sample were laid end to end to form a single thread. Would it be long enough to reach from the Earth to the Moon (385.000 kilometers).
