An intact length of dna consists of 320 total nucleotides (160 nucleotides/strands). a total of 95 cytosine nitrogen bases are found in the entire segment. How many molecules of adenine would be found in the segment of dna?

65

Explanation:

The DNA segment has a total 95 cytosine bases. Since cytosine makes hydrogen bonds with guanine base, this means that the DNA segment has a total 95 guanine bases.

Total guanine + cytosine bases in the segment= 95 + 95 = 190

So, a total of adenine and thymine bases in the DNA segment= 320-190 = 130

Since the number of adenine and thymine bases are equal in a double-stranded DNA molecule, the number of adenine bases in the given segment would be= 130/2= 65

the types of mutations include: missense mutation: this type of mutation is a change in one dna base pair that results in the substitution of one amino acid for another in the protein made by a gene. nonsense mutation: a nonsense mutation is also a change in one dna base pair.

explanation:

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
