All are in DNA.arrow_forwardA double-stranded molecule of B DNA contains 340 nucleotides. What information do you know based on the question and your understanding of the topic?arrow_forward
- The primary structure of DNA is held together with ___________ bonds, and the secondary structure is held together with _____________ bonds.arrow_forwardA large number of nucleotide base pairs along a DNA molecule is a specific region called a _____arrow_forwardA DNA strand consists of eight pairs of nitrogenous bases. How many different sequences of eight bases can you make? Explain how you found your answer.arrow_forward
- In the double helix of DNA, the ____________ bases of one strand exhibit complementary base pairing with the bases of the other strand.arrow_forwardPlease answer question: each sugar molecule is attached to one nitrogen base. the two strands of DNA are attached by bonds between the nitrogen bases on each side of the ladder. Each nucleotide base only bonds with one specific partner. The combination of two bases is called a base pair. Adenine always bonds with thymine. A-T, and Guanine always bonds with cytosine. G-C. Fill in the missing nitrogenous bases. I have attached the DNA strand to find the missing nitrogenous. Please find the incomplete DNA Molecule. The picture is the whole Figure broken into two pics because i could not get the whole picture into one.arrow_forwardUse the following information to answer the next question.A small segment of DNA has the following sequence:A – A – T – C – T – C – G – T – AThe sequence of the complementary DNA strand is a. C – C – G – A – G – A – T – G – C b. G – G – C – T – C – T – A – C – G c. T – T – A – G – A – G – C – A – T d. A – A – T – C – T – C – G – T – Aarrow_forward
