Answer 1

The building blocks of DNA are called nucleotides.
In the process of DNA replication, DNA makes a copy of itself. This process takes place in the nucleus of a cell.
Three ways that RNA differs from DNA are:
RNA is single-stranded, while DNA is double-stranded.
RNA contains the nitrogenous base uracil instead of thymine found in DNA.
RNA has ribose as its sugar molecule, while DNA has deoxyribose.
Uracil pairs up with adenine in RNA, not in DNA.
Transcription is the process of making an RNA copy of a piece of DNA. This process occurs in the nucleus of a cell.
DNA → A G C C T A G T C
RNA → U C G G A U C A G
(Uracil pairs up with Adenine instead of Thymine in RNA)
The three types of RNA are:
Messenger RNA (mRNA)
Transfer RNA (tRNA)
Ribosomal RNA (rRNA)
The building blocks of proteins are amino acids.
The "Central Dogma of Biology" is the principle that states that genetic information flows in one direction from DNA to RNA to proteins. This means that DNA is transcribed into RNA, which is then translated into proteins.

Answer 2

The building blocks of DNA are called nucleotides.

In the process of DNA replication, DNA makes a copy of itself. This process takes place in the nucleus of a cell.

Three ways that RNA differs from DNA are:

RNA is single-stranded while DNA is double-stranded.

RNA uses the sugar ribose, while DNA uses deoxyribose.

RNA contains the base uracil, while DNA contains the base thymine.

Uracil pairs up with adenine in RNA, while thymine pairs up with adenine in DNA.

Transcription is the process of making an RNA copy of a piece of DNA. This process occurs in the nucleus of a cell.

The complementary mRNA sequence for the following DNA sequence is:

DNA → A G C C T A G T C

RNA → U C G G A U C A G

The three types of RNA are:

Messenger RNA (mRNA)

Transfer RNA (tRNA)

Ribosomal RNA (rRNA)

The building blocks of proteins are amino acids.

The "Central Dogma of Biology" is the flow of genetic information in a cell. It states that DNA is transcribed into RNA, which is then translated into proteins.
