Answer:
D. New allergens that people are not aware of may be introduced.
Explanation:
While increasing mineral contents or vitamins, people might have a strong allergy to a certain type of ingredient that the scientists added in to the food.
Answer:
Explanation:
This is because the new cell is produced asexually. Therefore the mutated cells are similar to the parent.
Asexual reproduction refers to the process where a parent plants reproduce or replicate new plants by itself and the new plants carries the same set of chromosomal numbers thereby been genetically identical to the parent.
<span> Eukaryotic cells are a lot more complex. They
have a nucleus in a nuclear membrane, where DNA or other genetic
information is stored, as well as lots of organelles that serve
different functions.</span>
Answer:
4/16 (i.e. 25%)
Explanation:
A dihybrid cross is a cross between two organisms/lines/genes that are hybrids (i.e., heterozygous) for two different traits. In a standard dihybrid cross, there is a relation of complete dominance for both <em>loci</em>, i.e., there are two alleles that are completely dominant and thus mask the effects of the corresponding recessive traits. In a dihybrid cross involving two different genes that assort independently into gametes during meiosis, with dominant alleles "A" and "B" and recessive alleles "a" and "b", respectively, the expected phenotypic ratio will be 9:3:3:1 (ie. 9/16 A_B_, 3/16 A_bb, 3/16 aaB_ and 1/16 aabb), while the expected genotypic ratio of double heterozygous "AaBb" individuals will be 4/16, i.e. 25%.
Representation:
P generation >> AaBb (father) X AaBb (mother)
Gametes (for both parents) >> 1/4 AB; 1/4 Ab; 1/4 aB; 1/4 ab
F1 generation >> 1/16 AABB; 2/16 AABb; 2/16 AaBB; 4/16 AaBb; 1/16 AAbb; 2/16 Aabb; 1/16 aaBB; 2/16 aaBb; 1/16 aabb
Answer:
1). Bacterial increase, nucleotide, DNA, palindrome
2). Phage, plasmid.
Explanation: A restriction enzyme is one of the key enzymes in gene cloning, example is a restriction endonuclease. A restriction enzyme recognizes and cleaved DNA at specific DNA sequences to generate a set of smaller fragments. The smaller fragments of DNA produced by the restriction enzyme is then inserted into a suitable cloning vector whose DNA molecule has been also cleaved by the same restriction enzyme. The enzyme DNA ligase joins the DNA fragments together. Examples of cloning vectors are plasmids, and bacteriophages (phages)
