please answer quickly and accurately. Thank You!!
D) inhibit ATP production E) inhibit proteins synthesis 11. The following statement is true about enchromatin: A) Present in prokaryotes B) Does not exist in human C) Usually transcriptionally inactive Refer to the following list of enzymes to answer the following questions. The answers may be used once, more than once, or not at all. A. helicase B. nuclease ?.ligase D. DNA polymerase I E. primase 12) breaks hydrogen bonds between nitrogen bases and unwinds polynucleotide strands during DNA replication. Answer: 13) The nucleotide composition of a DNA molecule was found to be 12% "A" and 20% "T". This molecule is a: A) single-stranded DNA B) double-stranded DNA C) single-stranded RNA D) double stranded RNA E) none of the above 14. The following statement is true about nucleosome: A) typically contains 147 nucleotide pairs. B) Histone protein core is surrounded by DNA C) Contains H2A D) Contains H2B E) All of the above statements are true. 15) The leading and the lagging strands differ in that A) the leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the oppesite direction. B) the leading strand is synthesized by adding nucleotides to the 3' end of the growing strand, and the lagging strand is synthesized by adding nucleotides to the 5' end. C) the leading strand is synthesized continuously, whereas the lagging strand is synthesized in short fragments that are ultimately stitched together. D) both A and BExplanation / Answer
These answers are to the best of my knowledge.
11) D) usually transcriptionally active but i am a little confused with A) as they are present in both prokaryotes and eukaryotes.
12) Helicases
13) Single stranded DNA because if it was double stranded, composition of A and T would be same and if it was RNA, T would have been replaced by U.
14) All of the above statements are true.
15) C) The leading strand is synthesized continuously, whereas the lagging strand is synthesized in short fragments that are ultimately joined together.
