Dna amplification requires

Biology
1 answer:
never [62]4 years ago
6 0

Answer:

In order to study or detect individual genes or specific DNA regions or mutations of interest, it is often necessary to obtain a large quantity of nucleic acid for study. Rather than isolate a single copy of the target DNA from a large number of cells, it is often more useful to generate multiple copies of a target from a single molecule of DNA or mRNA, via an in vitro amplification method.

PLEASE HELP ASAP
oee [108]

Explanation: This is a type of genetic inheritance where neither of the genes is dominant over another. Thus both pair of the gene are expressed on the same LOCUS equally with none masking another. Therefore an   individual receive both  allele of a heterozygous  gene, and have equal phenotypic expression

An example is the AB  blood group in man, where both allele present on the same locus are fully expressed with no one dominant over another.

Incomplete dominance refers to a blend of  alleles where one does  not have  full dominance over another another, therefore gives a new phenotypic expression different from both alleles.

Which of the algae groups contain the same photosynthetic pigments as green plants, have lots of cellulose in their cell walls,
user100 [1]
<h2>Green Algae</h2>

Explanation:

  • Green algae (sing. alga) come in a heteromorph group of species and this is only a conventional name rather than biological classification. The group unites some predominant divisions like Chlorophyta and Charophyta.
  • Some species of Chlorophyta are considered to be the first ‘true’ plants by bridging between Protozoa and Plantae. Most of this division’s representatives are aquatic, they have chloroplasts and chlorophyll a and b, which are typical for plants. They could be unicellular, often colonial and even multicellular. The variety of the group is great in terms of their habitat, morpho-structure, reproductive system, etc. Some even live in symbiosis with fungi, but they are usually classified in a different division called Lichenophyta.
  • Hence, the answer is "green algae"
