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.

Solution A has a pH= 2 and solution B has a pH=10 what solution does have more hydrogen ions
Ivanshal [37]
Solution A have more hydrogen ions as pH level 2 indicates that it is highly acidic which means presence of H+ ions. On the other side sol B with ph10 has more OH- ions in it making it base in nature.

What structure, still found in cells today, was key in causing a change from chemical evolution to biological evolution?
PtichkaEL [24]

Answer:

Prokaryotic cells (bacteria) lack a nuclear envelope; eukaryotic cells have a nucleus in which evolution was thus reached in the early 1980s, when it was discovered an early stage of chemical evolution is thought to have been based on chloroplasts are still encoded by the organelle genomes.
