Unit 4 Review - Biology

In a molecule of double-stranded DNA, the amount of Adenine present is always equal to the amount of

• cytosine
• guanine
• thymine
• uracil

DNA replication results in two DNA molecules,

• each one with two original strands
• each one with two new strands
• each one with one new strand and one original strand
• one with two new strands and the other with two original strands

RNA contains the sugar

• ribose
• deoxyribose
• glucose
• lactose

Transcribe the following DNA strand: CTG AAT

• GAC TTA

• CTG AAT

• GAC UUA

• CUG AAU

The anti-codon 

• contains a sequence the same as the codon
• contains a sequence complementary to the codon 
• contains the base thymine

tRNA is involved in

• carrying amino acids 
• carrying ribosomes
• carrying glucose
• carrying lipids
