Duplications are repeated segments of genetic materials that result from unequal crossing over during meiosis or through a replication error prior to meiosis. They usually occur when homologous pairs do not line up correctly or in chromosomes with a lot of repeat sequences. Duplication of a segment of a chromosome would result in Genetic variability during evolution due to gene duplication.
Answer:
The correct answer would be C. The protein synthesized will contain many erroneous amino acids since the loss of one base will shift the reading of the encoded base sequence.
Deletion mutation that does not occur in the multiple of three bases can results in frame-shift mutation.
It changes the reading frame of nucleotide in DNA. Thus, the reading frame of codons in mRNA would also change.
Consequently, the sequence of amino acids in a polypeptide chain would change or alter. Thus, a protein would contain many erroneous amino acids.
An example of the same is shown below in the image.
<h3><u>Answer;</u></h3>
The bacteria require less energy to make offspring,
They do not need a partner
Also the reproduction is faster and rapid compared to sexual reproduction.
<h3><u>Explanation</u>;</h3>
- Asexual reproduction is a type of reproduction that involves one parent and produces offspring that are genetically identical to each other and to the parent.
- In sexual reproduction, on the other hand, two parents are involved, who produce reproductive cells called gametes that unite to form an offspring.
- <em><u>E. coli is a bacteria that reproduces asexually. An asexual reproducing organism can produce many offspring in a short period of time without utilizing energy to find a mate</u></em><u>. </u>
Incomplete dominance can happen in flowers such as snap dragons where a red flower plant and a white flower plant have an offspring that is neither red nor white but is a mix so in this case it would be pink. It does not support the blending theory as it does not get its colour from the dominant plant in this case but from both.
In the matrix of mitochondria the reactions known as the citric acid or Krebs cycle produce a chemical called NADH. NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP). In ATP the energy is stored in the form of chemical bonds.
