Why are genetically engineered mammalian cells sometimes needed to produce certain proteins instead of genetically engineered bacteria?
A. Mammal cells are larger and can produce greater volumes of protein.
B. Mammalian cells are not needed; bacterial cells can produce the same proteins as long as they have the gene that codes for it.
C. Mammal cells have more precise restriction enzymes.
D. Bacteria make proteins differently than mammals, and cannot make certain human proteins.
Answers
Answer:
C
Explanation:
As mammal cells have more precise restriction enzymes, it sometimes needed instead of bacteria. The correct option is C.
What is genetic engineering?Genetic engineering also referred to as genetic modification is a process that uses laboratory-based technologies to alter an organism's DNA makeup.
Because mammalian cells have more precise restriction enzymes, it is sometimes necessary to use them instead of bacteria.
Herbert Boyer and Stanley Cohen, biochemists, create genetic engineering in 1973 by implanting DNA from one bacteria into yet another.
There are three basic stepping stones to genetic engineering. These are:
Isolating DNA fragments from a donor organism.Inserting an isolated donor DNA fragment into a vector genome.Growing a recombinant vector in an appropriate host.Thus, the correct option is C.

The Green Revolution allowed countries that previously imported crops to become
crop exporters.
What is the Green Revolution?The Green revolution refers to the period of cultivation of high-yielding crops varieties especially grains by farmers beginning in the period of the 1940s to l960s.
The Green revolution resulted in increased food production among countries that usually imported food, so they became exporters.
Therefore, the Green Revolution allowed countries that previously imported crops to become
crop exporters.

homologous trait?
A. the wings of bees and birds
B. the forearm of different animals
C. the DNA of land animals
Answers
Answer:
the wings on bees and birds
An example of a homologous trait is the wings of bees and birds. The correct option is A.
What are homologous traits?The Theory of Evolution can be used to explain the homologous features of related species. According to this hypothesis, species develop over time from a common progenitor.
In order to adapt to the new environment, species separated from one another and developed new features. The variety of species observed on Earth today is the result of a process known as speciation.
The homologous features that are shared by related species are proof of their shared ancestry. For instance, despite being different, the wings of a bat and a bird share characteristics.
Therefore, the correct option is A. the wings of bees and birds.

An ampicillin-resistant, tetracycline-resistant plasmid, pBR322, is cleaved with PstI, which cleaves within the ampicillin resistance gene. The cut plasmid is ligated with PstI digested Drosophila DNA to prepare a genomic library, and the mixture is used to transform E. coli K12. Which Antibiotic should be added to the medium to select cells that have incorporated a plasmid
Answers
Answer:
tetracycline
Explanation:
A plasmid is a small, circular, double-stranded DNA molecule, which is physically separated from chromosomal DNA and is able to replicate independently. Moreover, plasmid transformation is the process by which exogenous DNA is introduced into a cell (usually a bacterial host cell). In this case, Escherichia coli K12 cells were transformed with the pBR322 plasmids that encode both ampicillin and tetracycline resistance genes. According to data, plasmids were firstly cleaved with the PstI type II restriction endonuclease within the ampicillin resistance gene, thereby these plasmids lose the ampicillin-resistance gene that allows selecting E. coli K12 cells by their resistance to ampicillin. In consequence, tetracycline is the only one selective marker that will indicate that the bacteria have incorporated the plasmid.
Classify these hypotheses about the ocean as falsifiable or non-falsifiable.
Answers
The hypotheses about the ocean as
Falsifiable: 1) Limestone erodes faster than basalt when exposed to ocean salt water 2) Shallower tide pools support more algae growth.
Non-falsifiable is: 1) The rugged Panama coastline offers a wonderful experience for fishing enthusiasts. 2) Warm ocean water is more enjoyable to swim in than cool ocean water.
Limestone erodes faster than basalt when exposed to ocean salt water.
This hypothesis is falsifiable. One could conduct an experiment in which samples of limestone and basalt are exposed to ocean salt water and the rate of erosion is measured and compared between the two samples.
The rugged Panama coastline offers a wonderful experience for fishing enthusiasts.
This hypothesis is non-falsifiable. The statement is subjective and cannot be tested or proven true or false. What one person considers a wonderful fishing experience may not be the same for another person.
Shallower tide pools support more algae growth.
This hypothesis is falsifiable. One could conduct an experiment in which algae growth is measured and compared between different depths of tide pools.
Warm ocean water is more enjoyable to swim in than cool ocean water.
This hypothesis is non-falsifiable. The statement is subjective and cannot be tested or proven true or false. What one person finds enjoyable may not be the same for another person.

Write down the functions of
1.microtubules
2.tripletsof microtubules
Answers
Answer:
Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility
Centrioles are cylindrical structures that are made up of protein tubes called microtubules. Specifically, nine groups of three microtubules, known as triplet microtubules, are linked together to make the walls of the cylinder.
Hope it helps :)
Answer:
Microtubules have several functions. For example, they provide the rigid, organized components of the cytoskeleton that give shape to many cells, and they are major components of cilia and flagella (cellular locomotory projections). They participate in the formation of the spindle during cell division (mitosis).
triplet microtubules are linked together to make the walls of the cylinder.
