The hippocampus and medial entorhinal cortex
Answer:
Chloroplasts are found in plant cells only because chloroplasts contain chlorophyll which is essential for photosynthesis. Chlorophyll traps sunlight and uses it to prepare food for plants by the process of photosynthesis.
The first step I would use is to use a magnet to remove the iron filings. This is because only metal is attracted to magnets. I would then use a sieve to filter the sand and salt from the gravel. This is because the gravel will have a larger diameter than the sand and salt particles, and will stay behind while the salt and sand will pass through the sieve. Finally, I would remove the salt from the sand by placing the mixture in water. The sand will tend to sink to the bottom while the salt will dissolve into solution.
Answer:
Each strand has a 3' end (unbound hydroxyl group) and a 5' end (hydroxyl group of deoxyribose sugar), the two strands run antiparallel to each other. (Ans. E)
Explanation:
DNA is known as Deoxyribonucleic acid. It is a complex organic molecular structure and present in all eukaryotes, prokaryotes and some viruses. For the transmission of inherited traits DNA codes genetic information.
It is a double-helix polymer consist of two spiral DNA strands fold around each other. Each strand of DNA is made up of a long chain of nucleotides. DNA's nucleotide consist phosphate group attached with deoxyribose sugar and nitrogenous bases two purine (adenine, guanine) and two pyrimidine (cytosine, thymine)
DNA have two distinct ends, one is 5'prime another is 3'prime. It means 5' and 3' carbon present on the sugar. 5' prime end consist phosphate group and 3' prime end consist hydroxyl group.
