Answer: Hello! xoxo

Upon analysis of the results, a hypothesis can be rejected or modified, but it can never be proven to be correct 100 percent of the time. For example, relativity has been tested many times, so it is generally accepted as true, but there could be an instance, which has not been encountered, where it is not true.

Can anybody answer this
NARA [144]

Answer:

Options A, B, E, and F are correct

Explanation:

A). In the cell cycle, DNA replication is a process by which a duplicate DNA strand is produced with the help of replication machinery (enzymes, nucleotides, etc.). The overall process ensures that the newly developed strand is free of any mutations (errors) causing the production of wrong proteins at later stages. Although, there are chances of positive, negative or neutral mutations, the replication machinery aims to avoid any such errors at this stage.

B). DNA stores genetic information in the form of codes (known as codon) which needs to be translated in the form of proteins. This process is known as a transcription by which messenger RNA (mRNA) is produced in the nucleolus. Thereon, it is transported outside to encode proteins with the help of ribosomes. The process of copying genetic information on DNA in the form of mRNA is known is transcription.

E). The figure shown is also known as the central dogma of life. According to which, DNA (genetic information) is transcribed into RNA, which is then translated to proteins. In brief, RNA molecules brings the information from nucleous to ribosomes and make proteins. These proteins are often enzymes, hormones, and other biomolecules that perform the important functions in living organisms.

F). DNA and RNA are two types of nucleic acids responsible for all types of life on Earth. Since both of them are well recognized as nucleotides, they are made up of the same genetic building blocks known as nucleotides. Further, each nucleotide is comprised of a five-carbon sugar, a phosphate group, and a nitrogen base. The sequence of these nucleotides is responsible for the production of specific types of proteins.

Which is the final electron receptor in the electron transport system of cellular respiration
Zepler [3.9K]

Oxygen is the final electron acceptor in the electron transport chain, which allows for oxidative phosphorylation. Without oxygen, the electrons will be backed up, eventually causing the electron transport chain to halt.
