OlgaM077 [116]

Answer:

With respect to the differences in the DNA sequence of six species, including the human one, it is true that the DNA sequences may vary but the aminoacid sequences are identical.

Explanation:

Options for this question:

  • <em>The DNA sequences may vary but the amino acid sequences are identical. </em>
  • The nitrogen bases in the nucleotides must also be different in each.
  • The process in producing additional DNA, replication, is identical in all six.
  • The process of producing DNA, or replication, varies due to the differences in the DNA codes.

The different species that exist have specific genomes for each of them, this is the <u>genetic information contained in the DNA varies from one species to another</u>, as can be seen in the scheme (see image). However, the genetic code is universal, and does not vary from one species to another.

The genetic code is found in the RNA molecule and is a sequence of nucleotides that, organized in triplets (codons), are responsible for the synthesis of specific amino acids. An RNA molecule contains the information necessary for protein synthesis.

The scheme shows the differences of five species with respect to the human, based on the respective DNA sequences. But what it does not show is a universally accepted truth, that the nucleotide sequence encoding an amino acid is the same for each of these species.

Pulse-chase experiments and protein location
ExtremeBDS [4]

Answer:

The correct answer is option - phagocytosis.

Explanation:

The explained experiment is the pulse-chase experiment in this the cells that are involved are macrophages. Macrophages are the immunity cells that have a large number of the lysosomes for killing the pathogens enters in the cell brought into the cell through the process of phagocytosis.

Phagocytosis takes place with the help of the enzyme called hydrolytic enzyme that is synthesized in the endoplasmic reticulum and modified by Golgi and moves to the lysosome.

Thus, the correct answer is option - phagocytosis.
