Review DNA and RNA TRANSCRIPTION

DNA and RNA are types of​ (a)  

• nucleic acids
• protein
• carbohydrate
• lipid

DNA or RNA are made up of repeating​ (a)  

• nucleotides
• amino acids
• monosaccharides
• fatty acids

Nucleotides have 3 parts -

[check 3 answers]

• nitrogen base

• pentose (5-carbon] sugar

• phosphate

• amino acid

Each nucleotide in DNA has one of 4 nitrogen bases -

Humans have thousands of genes that combine in different ways to help create unique individuals. Where is the genetic code primarily located?

• Ribose sugars in RNA

• Phosphates in DNA

• Nucleotides in DNA

• Exons on RNA

According to Chargaff's rule, DNA nitrogenous bases are held together by ​ (a)   .

Adenine is always paired with ​ (b)   , and Cytosine is always paired with ​ (c)   .

• hydrogen bonds
• Thymine
• Guanine
• Cytosine
• Adenine
• Uracil

During transcription, RNA polymerase moves along a DNA template (strand) and adds complementary nitrogen bases and a strand of mRNA is transcribed (copied).

Adenine is always paired with ​ (a)   , and ​ (b)   is always paired with ​Guanine .

• Uracil
• Cytosine
• Adenine
• Thymine
• Guanine

According to Watson & Crick, the shape of DNA is called the double helix with 2 strands, and is made up of -

• deoxyribose sugar

• phosphate group

• nitrogenous bases A, T, C & G

• Ribose sugar

• nitrogenous bases A, U, C & G
