Answer:
Nickel, Ni, atomic number 28
:
Nickel, Ni, atomic number 28 Is a transition metal. It falls in the "d" region. 4 of Period, group 10.
Calcium and magnesium are alkaline earth metals, and antimony is a metal in the nitrogen group.
Prokaryotes are identified with bacteria: most live as single-cell organisms but some bacteria associate in a chain. Prokaryotes have their DNA in the cytoplasm of the cell. Eukaryotes ("Eu" for true) have a nucleus, a compartment separated from the rest of the cellular content, which contains the DNA.
In both of eucaryotic an procaryotic cell, you can find DNA, all kinds of RNA, Cytoplasm, ribosomes, and a cell membrane,
In procaryotic cell only you can find: a cell wall (located outside the cell membrane), you may find also pili, capsids, plasmids, and flagella.
In a eucaryotic cell only, you can find Nucleus (which contain the DNA), mitochondria, endoplasmic reticulum,
Answer:
- B the kinds of molecules involved in the reaction
- C the kinds of elements that make up a molecule
- D whether the molecules are products or reactants
Explanation:
When modelling the chemical reaction, it is important that the process is explained such that people looking at the model understand what happened in terms of the reactants and products and how they came to be either.
Leann will therefore have to include the kinds of molecules involved in the reaction be they products or reactants. She will also have to include which elements make up the molecules for instance a water molecule would have the elements Hydrogen and Oxygen.
Finally she would have to indicate which molecules are reactant and which are products. Reactants usually stay to the left side of the reaction equation and products stay to the right.
Answer:
A truncated protein refers to a protein that gets shortened due to a mutation, which does not allow the process of translation to take place properly. The formation of a truncated protein can take place due to a frameshift mutation of one or two base pairs. In such kind of mutation, a single or two base pairs get withdrawn from the sequence resulting in the formation of a completely changed triplicate codon sequence, which may result in the generation of a truncated protein comprising a different set of amino acids.
A nonsense mutation can also result in the formation of a truncated protein. A nonsense mutation generally codes for certain kinds of amino acid, however, post mutation can get converted into a stop codon. This transformation can result in the formation of a truncated protein.
Deletion or insertion at the chromosomal level can also result in the formation of a truncated protein. As insertion and deletion of a certain concentration of DNA can probably lead to the formation of a novel codon that can either be a nonsense codon or a stop codon, which may eventually result in the formation of a truncated protein.
Hence, the correct answers are statements 1st, 2nd, 3rd, 4th, and 6th
Answer:
III-6
Explanation:
Obligate carriers, or obligate heterozygotes, are those individuals that may be unaffected clinically, but must possess a copy of the mutant gene. For autosomal recessive conditions, obligate carriers can be the offspring of a parental mating of two carriers (50% of offspring will also be carriers). They can also be produced by a parental mating of a carrier by an affected individual (50% of offspring will be carriers).
