Question

please I need the answers not the explaining

Transcription

1. Transcription describes the process of copying _______ into _________. The enzyme responsible for transcription is ___________. This process occurs in the ________. A single mRNA may code for several proteins due to __________ which is used to remove noncoding regions called _________.

Translations

1. Translation is the process of __________. The mRNA strand is read by the ________ which assembles the _________. The three steps of translation are _________. This process primarily occurs in the ________.

DNA replication

1. DNA replication occurs in the __________. In this process the DNA is unwounded by _________ and it is then copied by ___________. At the end of the process each new double-stranded DNA will have ____________. This is called _____________ replication.

Answer 1

1. Transcription describes the process of copying DNA into RNA. The enzyme responsible for transcription is RNA Polymerase. This process occurs in the nucleus. A single mRNA may code for several proteins due to alternative splicing which is used to remove noncoding regions called introns.

Translations

1. Translation is the process of protein synthesis. The mRNA strand is read by the ribosomes which assembles the amino acids. The three steps of translation are initiation, elongation and termination. This process primarily occurs in the cytoplasm.

DNA replication

1. DNA replication occurs in the nucleus. In this process the DNA is unwounded by helicase and it is then copied by DNA Polymerase. At the end of the process each new double-stranded DNA will have one old strand and one new strand. This is called semi-conservative replication.
