Transcription (DNA -> mRNA)

Transcription

The first step of Protein Synthesis is Transcription

Multiple Choice

The first step of protein synthesis is.....

• replication

• mitosis

• translation

• transcription

What is Transcription?

• transcription copies a specific gene that will be made into a protein

• transcription is making a copy of DNA into a copy of mRNA

• transcription takes place in the nucleus

Multiple Choice

Which Nucleic Acids can be found in the nucleus?

• DNA only

• DNA & RNA

• RNA only

• enzymes only

Fill in the Blank

During transcription a specific _____________ is copied into mRNA.

Transcription requires enzymes

• RNA polymerase

• RNA is only synthesized using the template strand of DNA

• That means, only one side of the opened DNA molecule is used to make mRNA

Multiple Select

An enzyme is

• a protein that makes chemical reactions go faster

• a term that ends in "ase"

• RNA polymerase

Multiple Choice

The molecule that synthesizes the mRNA inside the nucleus

• DNA polymerase

• Nucleotides

• RNA polymerase

• helicase

Only one part of the chromosome is opened at a time during transcription

​

Multiple Choice

True or False:

Transcription makes a copy of the FULL chromosome at one time.

• true

• false

Multiple Choice

DO YOU REMEMBER?!

What is the nitrogen base ONLY found in DNA?

• adenine

• uracil

• guanine

• cytosine

• thymine

One gene codes for only one protein.

• The chromosome only transcribes one gene at a time

• Cells need thousands of proteins for survival

• Therefore your DNA contains thousands of different genes

Multiple Choice

What is a chromosome?

• a piece of DNA

• DNA wrapped around protein

• the complete genome of an organism

Transcription Base Pairing Rules:

A --U

G--C

There is no Thymine in RNA, instead Uracil is used. This allows the cell to protect the RNA from being destroyed before the protein is made.

Multiple Select

Adenine pairs with

• uracil

• thymine

• cytosine

• adenine

Transcription takes place in the Nucleus

• after the mRNA is made, it leaves the nucleus

• mRNA enters the cytoplasm and is picked up by the ribosome

• This is where transcription ends

• the next step is TRANSLATION....

Multiple Choice

The DNA strands are held together

• with covalent bonds

• with sugar molecules

• with hydrogen bonds between bases

Multiple Choice

Which RNA bases would pair with TACGAA in transcription? 

• AUGCUU
• ATGCTT
• GCATCC
• GCAUCC

Multiple Choice

Transcribe the following DNA sequence into RNA:

• TTU UTC CCG UGC

Multiple Choice

TRANSCRIBE this DNA sequence into RNA: AUG CGC TCT

• AUG CAA UGA

• ATG CAA TGA

• UAC GCG AGA

• TAC GTT ACT

Multiple Choice

Choose the nucleotide sequence of the RNA strand that would be complementary to the following strand: 
GTAGTCA

• UATUAGA
• ACGACTG
• CAUCAGU
• CATCAGT

Multiple Choice

Which is the mRNA molecule that would be transcribed from this DNA template:
TGGCAAGTACGT

• ACCGTTCATGCA
