Margarita [4]

Answer:

Memories aren't just stored in one part of our brains. Different parts are stored in different brain regions, but the hippocampus is memories are formed and later accessed.

How are the terms chromatin and DNA related?
Ivan

Answer:

Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell's genetic instructions. The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus. Changes in chromatin structure are associated with DNA replication and gene expression.

Can you tell the difference between the original and the replicated strand
kati45 [8]

Answer:

Original strand is the old strand and replicated strand is new strand.

Explanation:

DNA is replicated by the semi-conservative way which means the new strand is replicated over the old strand and one DNA duplex has one new strand and one old strand. So the original strand is the old strand and the replicated strand is the strand that is synthesized over the original strand.

In DNA the replicated strand is made by adding nucleotides complementary to the opposite nucleotide present in the template or original strand. Adenine and thymine make complementary base pairing with each other and guanine and cytosine makes complementary base pairing with each other.
