Answer:
f. Plasmid taken up by bacterium
c. Isolate bacterial plasmid
a. Select the gene of interest + insert into plasmid
b. Protein product harvested from bacteria
d. Bacteria replicate
e. Cloned gene harvested from bacteria
Explanation:
Genetic modification refers to the methods used to obtain genetically modified organisms (GMO). Plasmids are widely used in genetic engineering to transfer target genes into bacterial cells and/or cells of higher organisms. For example, in plants, the Agrobacterium-mediated transformation process involves the use of this bacterium to obtain GMO:
1) A T-DNA plasmid is removed from Agrobacterium tumefaciens and this transfer DNA (T-DNA) is cleaved using a specific endonuclease enzyme
2) A piece of foreign DNA fragment (target gene sequence to insert) is split off and then integrated into T-DNA
3) Recombinant plasmids are re-inserted into Agrobacterium and then bacteria are used to insert target DNA into plant cells
4) Plant cells grown in culture in order to obtain GMO adult plants with the desired genetic modification

Which of the following is NOT true of Chlorophyll?
A) It reflects all the colors of light but absorbs the green.
B) It reflects the green wavelengths of light and absorbs all the rest.
C) It is essential for photosynthesis?
Answer: A.It reflects all the colors of light but absorbs the green.
Explanation:
Photosynthesis, which gives plants their green hue, requires chlorophyll. Therefore, option (A) is not true.
What is chlorophyll?Chlorophyll, the pigment that gives plants their distinctive green hue, is crucial to the process of photosynthesis, which provides energy for a plant's metabolism, growth, and reproduction. Because chlorophyll does not absorb the green wavelengths of white light, it is chlorophyll that gives plants their green hue. The plant appears green because it reflects that particular light wavelength. Autotrophs are plants that produce their own sustenance through photosynthesis.
The stroma, which is the area between the thylakoid and chloroplast membranes, is where the chlorophyll, the green pigment, is found.

On average, a 1°C change in temperature is enough to put corals at risk of bleaching and death. Based on the slope of the trendline, in how many years will global temperatures be 1°C above average? Show your work and justify your answer.
It takes 50 years to rise global temperatures to 1°Celsius.
It takes 50 years to rise global temperatures to 1°Celsius if the temperature increases per decade is 0.18 °Celsius. From 1880, global temperature increased at an average rate of 0.07°Celsius (0.13°F) per decade but due to industrial revolution the average rate in global temperature increase double i. e. 0.18°Celsius.
If global temperature increases with the rate of 0.18°Celsius per decade, it takes about more that 50 years to reach global temperature to 1°Celsius so we can conclude that 50 years is needed to rise global temperatures to 1°Celsius.

Which process occurs as various body parts form in a developing embryo?
options:
Meiosis
Fertilization
Differentiation
Answer:
The correct answer is differentiation.
Explanation:
The process of development during which the cells of the embryo specialize and the origination of different tissue compositions take place is known as embryonic differentiation. An organism is formed of distinct cell types, with each exhibiting specific functions. During embryogenesis, differentiation of cells is essential for the cell, organ, tissue, and organism's identity.
With the development of an embryo, the individual cells start to differentiate. In the embryo, the differentiation of cells takes place by both extracellular and internal cellular factors. The phenomenon of embryonic development plays an essential part in the proper development of an organism.

In sheep, white wool is dominant over spotted wool. If 10 purebred white wool sheep (TT) are crossed
with 10 spotted wool sheep (tt), how many offspring will have spotted wool?
05
O 10
ОО
04
Answer:
0
Explanation:
This question involves a single gene coding for wool color in sheeps. The allele for white wool (TT) is dominant over the allele for spotted wool (tt). This means that a sheep with an heterozygous genotype (Tt) will be white-wooled.
In this cross, 10 purebred white wool sheep (TT) are crossed with 10 spotted wool sheep (tt). This will give rise to all offsprings with heterozygous genotype: Tt (see attached image for punnet square). Since, white wool (T) is dominant, all the offsprings will have a white wool and none i.e. 0 will have a spotted wool.

What is the correct sequence of molecules involved in protein synthesis from beginning to end?
Answer:
The correct sequence of events in protein synthesis is transcription then translation. First, during transcription DNA is copied to mRNA in the nucleus. Then, mRNA is edited, processed and exported to the cytoplasm. Next, translation occurs.
Explanation:
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein. The process in which the messenger RNA (mRNA) molecule on a ribosome is decoded to produce a sequence of amino acids for protein synthesis. The process in which a strand of messenger RNA (mRNA) is synthesized by using the genetic information found on a strand DNA as a template.
The correct sequence of molecules involved in protein synthesis from beginning to end - DNA → mRNA → tRNA → Protein
Protein synthesis is a two-step process that involves transcription and translation to make proteins from a DNA sequence through the help of other molecules and organelles.
Transcription is the process of copying genetic information from the DNA sequence into the mRNA sequence that moves to the cytoplasm.The translation starts in the cytoplasm that is a translation of mRNA molecules to amino acid chains.mRNA molecules bind to the ribosome and with the help of tRNA molecules form an amino acid sequence.These amino acids chain are called peptide chains or proteins.Thus, the correct sequence of molecules involved in protein synthesis from beginning to end - DNA → mRNA → tRNA → Protein

Answer:
1. All red offsprings
2. All roan (RW) offsprings
Explanation:
According to this question, the allele for red color (R) is codominant with the allele for white color (W). Hence, an heterozygous cattle will give a roan color (RW).
- for cross 1 between RR and RR, only R gametes will be produced by both parents, hence, all the offsprings of this cross will possess a RR genotype i.e. all red traits
- Also, in cross 2 between RR and WW parents, RR will produce gametes R while WW will produce gametes W, hence, all the offsprings will have a genotype RW i.e. roan color

which of the following correctly describes the process being illustrated?
During prophase I of meiosis I, alleles cross over and recombine to form non-identical haploid chromatids. Therefore, option , (D) is the process being illustrated.
What happens in prophase I ?Prophase I of meiosis I is a process that consists of five distinct stages during which genetic material in the form of alleles undergoes crossover and recombination to generate non-identical haploid chromatids. Prophase I of meiosis I is the first step of meiotic division.
The first stage of meiosis is known as Prophase 1, and it is differentiated into five distinct phases: leptotene, zygotene, pachytene, diplotene, and diakinesis.
In what is referred to as the synaptonemal complex, the paired chromosomes, one of which is of paternal origin and the other of which is of maternal origin, associate with one another along the entirety of their length. Pachytene is the name given to this stage of meiotic prophase I because at this point the paired chromosomes have compacted and appear to be fat.
