Explanation:

Answer:

stop codon

hope this helps, good luck :)

UAA is a codon that signals to stop making a protein, and so it is therefore called a stop codon.

Codon may be characterized as a sequence or collection of three consecutive nucleotides in a DNA or RNA molecule that significantly codes for a specific amino acid. These sequences of nucleotides give a signal to the start or end of translation.

A stop codon is also a sequence of three nucleotides (a trinucleotide) in DNA or messenger RNA (mRNA) that specifically signals a halt or inhibits to protein synthesis in the cell. Out of 64 different trinucleotide codons, there are only three stop codons are there, namely UAA, UAG, and UGA.

The start codon is the initial set of codons in an mRNA transcript that is translated by a ribosome. CAG is a start codon. Nonsense codons also play an important role.

Therefore, UAA is a codon that signals to stop making a protein, and so it is therefore called a stop codon.

Answer:

recessive

Explanation:

The inheritance pattern of the congenital enzyme deficiency form of the disease is autosomal recessive. Hb M is inherited in an autosomal dominant pattern. There is no association between sex and the frequency of congenital methemoglobinemia.

Methemoglobinemia is an autosomal recessive congenital disorder. It means that both copies of the gene are found to be recessive in order to express a phenotype.

The Dominant trait may be defined as a form of trait which governs by the presence of at least one dominant copy of that gene.

Methemoglobinemia may be defined as a blood disorder in which very little amount of oxygen is delivered to your cells. Cells may feel the scarcity of oxygen.

If an individual is affected by this disorder, both the copies of its gene are found in a recessive form in order to mask the effect of a dominant copy.

Therefore, it is well described above.

Answer:

D

the skeletal system provides protection for the brain and spinal cord

Answer:

B

Explanation:

DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to discover history of a living organism and to produce proteins, which are the complex molecules that do most of the work in our bodies

Answer:

Meiosis is a process in which sex cells, also known as gametes are made. Meiosis is different from mitosis in a lot of ways, one being that mitosis creates identical daughter cells and meiosis creates unique daughter cells. Meiosis is important because it allow for the creation of a meiosis nucleus. Cells produced by meiosis will be used in haploid, where each member of the next generation is genetically unique.

Cells produced in sexual reproduction will have half of the genetic information of body cells and will be genetically unique. This is necessary because when a sperm and an egg fuse together in sexual reproduction. They form a zygote: the first body of a new individual.

The new individual will now have cells that are diploid, meaning they have two sets of chromosomes. They zygote will have to do a lot of mitosis allowing it to grow quickly and ensure that all of its cells are genetically unique.

Explanation:

Electroplating involves the coating of one metal on another metal. It is an electrochemical process. The positive electrode is the coating metal while the negative electrode is the metal on which the coating is to be performed.

Since copper is to be coated on an iron nail. A copper plate is made the positive electrode while the iron nail should be the negative electrode.

The electrolyte used in the process should be a copper salt e.g CuSO4 solution.

As electrolysis progresses, the copper electrode(positive electrode or anode) gradually wears away due to the fact that the copper ions are going into the solution and are being deposited on the iron nail.
