Answer:

25 nucleotide sequence pair

Explanation:

There are four nucleotide sequence pair present in DNA. and if we have 100 nucleotide so 25 nucleotide sequence pairs will be formed and each pair contains adenine (A), cytosine (C), guanine (G), and thymine (T).

Cytosine nucleotide paired with guanine nucleotide and Adenine nucleotide paired with thymine nucleotide . They have hydrogen bonds between each bases.

<span>I think the pKa for acetic acid is about 4.74. Therefore Acetic acid/acetate buffer will work best at 4.74 +/- 1 pH unit and so the pH 8 is far removed from that. Hence it would not buffer at that pH at all.</span>

In which reproductive cycle of the virus does the viral DNA integrates with the host DNA?

zzz [600]

Answer:

Bacteriophages have a lytic or lysogenic cycle.

Explanation:

The lytic cycle leads to the death of the host, whereas the lysogenic cycle leads to integration of phage into the host genome. Bacteriophages inject DNA into the host cell, whereas animal viruses enter by endocytosis or membrane fusion.

In garden peas, one pair of alleles controls the height of the plant, and a second pair of alleles controls flower color. The al

Lerok [7]

Answer:

The parent's genotypes are:

Ddpp - tall, white parent

ddPp - dwarf, purple parent.

Explanation:

This question involves two different genes coding for height and flower color in pea plants. The alleles for tallness (D) and purple color (P) are dominant over the alleles for dwarfness (d) and white color (p) respectively.

According to this question, a tall plant with white flowers is crossed with a dwarf plant with purple flowers to produce the following proportion of offsprings: 1/4 tall purple, 1/4 tall white, 1/4 dwarf purple, and 1/4 dwarf white.

Since some of the offsprings contain recessive alleles for both or either genes, the dominant traits of the parent is controlled by an heterozygous genotype. This means that the tall plant with white flowers has a genotype: Ddpp while the dwarf plant with purple flowers has the genotype: ddPp. In a cross between Ddpp × ddPp, 1/4 of each combination of alleles is produced in the offsprings (see punnet square in the attachment).

Does the park or the forest have greater biodiversity?

Gennadij [26K]

Answer:

The forests

Explanation:

Forests are so much more than a collection of trees. Forests are home to 80% of the world's terrestrial biodiversity. These ecosystems are complex webs of organisms that include plants, animals, fungi and bacteria. Forests take many forms, depending on their latitude, local soil, rainfall and prevailing temperatures.
