DNA TO PROTEIN SYNTHESIS

lagging strand

The strand in replication that is copied 3' to 5' as Okazaki fragments and then joined up.

leading strand

the new complementary DNA strand synthesized continuously along the template strand toward the replication fork in the mandatory 5' to 3' direction

Ligase

bunds Okazaki fragments

Okazaki fragments

sections of copied DNA created on lagging strabd

Helicase

unwinds DNA

DNA polymerase

builds new DNA strand by adding complementary bases

single strand binding protein

stabilizes DNA molecule during replication

lagging strand

strand that is copied continuously

initiates the synthesis DNA by creating short RNA segment

primase

transcription

synthesis of an RNA molecule from a DNA template

Translation

Process by which mRNA is decoded and a protein is produced

where does transcription happen

nucleus

where does translation happen

cytoplasm

RNA polymerase

uses DNA as a template to synthesize RNA

Which of the following pairs of nitrogen bases is purine?

Adenine and Guanine

A guanine molecule is always bonded to its complementary base with

three hydrogen bonds

The DNA strand which transcribes RNA is called the

sense

antisense

non-coding DNA gene

strand while the other strand, which does not play any role in transcription is known as the

the antisense

which is the first event in translation in eukaryotes

ribosome subunits bind to the mRNA

the joining of nucleotides to extend a new strand of DNA is known as

elongation

DNA is composed of repeating

nucleotides

Which of the following is NOT TRUE of a codon?

It extends from one end of a tRNA molecule.

Which component is not directly involved in translation?

DNA
