Question

what is the central dogma. of molecular biology define the terms duplication and replication

Answer 1

The central dogma of molecular biology describes the two step process, transcription and translation, by which the information in genes flow into proteins, DNA to RNA to Protein.
Duplication= A type of chromosomal aberrations in which a region of the chromosome is repeated.
Replication= The process by which double stranded DNA makes copies of itself,each strand as it separates , synthesizing a complementary strand.

Answer 2

DNA and RNA

                         

DNA and RNA are the central dogma of life.

DNA makes RNA, and RNA builds protein in our body. Proteins of our body are made by RNA. This process starts from DNA.

DNA makes RNA with the help of Oxygen and RNA starts to make protein. Proteins are very important structure of Human body.

In this process of making RNA, There are 3 important processes and they are as follows:

1) Transcription

2) Translation

3) Replication

DNA stands for => Deoxyribo Nucleic Acid

RNA stands for => Ribo Nucleic Acid.

=> DNA makes RNA and the RNA builds protein in our body.

=> formation of new DNA from old DNA is called as DNA REPLICATION.

=>   Central dogma of life was first stated by Francis Crick in 1957
