If one strand of DNA double helix has the following nucleotide sequence ATCGGTCAAGCTAGG what would the dna complementary stand r
joja [24]

Answer:

TAGCCAGTTCGATCC

Explanation:

In DNA, there are 4 different nucleotide bases. Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).

A (adenine) always pairs with T(thymine) and C(cytosine) always pairs with G (guanine).

If we have the strand:

ATCGGTCAAGCTAGG  

We have to pair A with T, and C with G. Therefore, the complementary strand of DNA will be:

TAGCCAGTTCGATCC

Which of these is NOT a way, or a proposed way, to store nuclear fuel rods after they have been used in a nuclear reactor? A) pu
Ainat [17]
The answer is C.)sending them on the shuttle to be suspended in space. This is the answer because  after  the nuclear fuel rods come out of the reactor, they go into a deep pool to cool off. Then they are then stored in concrete and lead-lined casks for dry storage, until, ultimately, the US government builds a deep underground storage facility to house them permanently. They are never sent on the shuttle to be suspended in space<span>. It would be too costly and too dangerous.</span>

Answer:a) decreased chromatin condensation

Explanation:

During eukaryotic cell division a chromatin becomes obvious and it is simply a mass of genetic material made up of DNA and proteins which condenses to form chromosomes.

The chromatin primarily function in the compression the DNA into a unit so compacted that will be so tiny and can fit within the nucleus.

Chromatin condensation is driven by condensins and interactions between histones.

Condensins however, are large protein complexes whose central role in cell division is chromosome organization and segregation.

Chemical manipulation as stated above is decreases the rate of chromatin condensation.
