At low frequencies during DNA replication, an extra nucleotide maybe inserted into the DNA strand. If this occurs within a gene,

Answer:

1. It could result in a loss of function of the protein product

2. It could result in a protein product with excessive activity

3. It could result in altered structure of the protein

Explanation:

Any changes that occur in the nucleotide sequence in the DNA of an organism is known as a mutation. Various forms of mutation can occur in the DNA sequence of an organism which could be as a result of insertion or deletion of a nucleotide in the DNA sequence.

Insertion of an extra nucleotide into a DNA strand within a gene could have any of the following effects on the protein protein;

1. It could result in a loss of function of the protein product of the gene whereby the protein can no longer carry out its normal functions

2. It could result in a protein product with excessive activity other the normal range at which it functions.

3. It could result in altered structure of the protein either in the primary, secondary, tertiary, or quaternary structure

Which cytoskeleton fibers are found in cilia and flagella?
kodGreya [7K]

Answer:

Microtubules are found in cilia and flagella .Microtubules are the thickest type of cytoskeleton fiber .Structurally they are hollow tubes that can dissolve and reform very quickly.Functionally, they provide movement to the to the organelles and pull the chromosome to their poles at the time of cell division

Which of Mendel's laws or principles explains that traits are passed from parents to offspring individually instead of as pairs,
sertanlavr [38]
The law of segregation is the Mendel’s laws or principles explain that traits are passed from parents to offspring individually instead of as pairs, groups or sets. So the correct option is option “C” as far as the given question is concerned. This is a law or principle which states that during the formation of gametes, two copies of each heredity factors separate out so that the new offspring can get one factor of both the parents. This law was the first law in this direction.

What does a single-celled prokaryote, like a bacteria, have in common with a single-celled eukaryote, like an amoeba? Select the
densk [106]

Answer: Both are single-celled microorganisms which contains plasma membranes, cytoplasm, ribosomes, DNA

Explanation:

Cells are the smallest functional unit of organisms which are classified under two main categories namely:

--> prokaryotic cells and

--> eukaryotic cells.

Prokaryotes are unicellular or single-celled organisms which do not possess true nuclei. Their cell structure is simple as there is NO definite nucleus and the chromosomes lie free in a particular part of the cell. Examples of organisms that belongs to this group are the bacteria. They can only be seen through a high power of a light microscope and are found in air, water, soil and living organisms. The general structure of prokaryotes like bacteria contains Chromosome ( single DNA strand coiled up), cytoplasm, ribosome which are few cell components among others.

Eukaryotes are organisms which possess a definite or true nuclei. The cell structure is complex and highly organized with a well-defined nucleus (meaning its DNA is surrounded by a membrane). Many structures called the cell organelles are present which include: mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes with other cell components, that is the cytoplasm, plasma membrane and ribosomes. Each organelle carries out a certain type of work. Examples of organisms that belongs to this group are the amoebas.

From the explanation above, both bacteria and amoeba are single- celled organisms which contains plasma membranes, cytoplasm, ribosomes, and DNA.
