The following picture must be
DNA because it is double stranded
DNA because it is single stranded
RNA because it is single stranded
RNA because it is double stranded
Which explanation is TRUE regarding the structures of DNA and RNA, and how do they related to replication and the expression of a gene? (Check all that apply)
Replication involves copying a whole molecule to produce a double-stranded molecule of DNA. RNA is single-stranded and is transcribed from a portion of one strand of DNA to produce a protein.

Why is DNA replication necessary?
It is very small and very complicated.
It is in everything that is important for all living things.
It serves as the blueprint for the genetic make-up of all living things.
It provides organisms with the energy they need.
What is the purpose of transcription?
RNA ---> Protein
RNA ---> DNA
DNA ---> Protein
DNA ----> RNA
The enzyme pictured above is necessary for the process of DNA replication. It breaks down the hydrogen bonds found between the nucleotides that hold the two DNA strands together. Identify the enzyme.
Single-Strand Binding Protein
Helicase
Endonucleus
DNA Polymerase
DNA is composed of two complementary strands. This is reflected in the fact that
the number of cytosines (C) in one strand is always double the number of guanines (G) in the other strand.
the number of guanines (G) in one strand is always equal to the number of adenine (A) in the other strand.
the number of thymine (T) in one strand is always double the number of cytosines (C) in the other strand.
the number of adenines (A) in one strand is always equal to the number of thymine (T) in the other strand.
What is the complementary mRNA sequence to the DNA sequence A-T-T-G-C-A?
T-A-A-C-G-T
U-A-A-C-G-T
U-A-A-C-G-U
T-A-A-G-C-U
Which material bonds freely floating amino acids in the cell's cytoplasm?
DNA
mRNA
tRNA
proteins
The process by which DNA is transferred to a messenger RNA (mRNA) is called
transcription
transition
translation
translocation
DNA is composed of two chains with nitrogenous bases that are complementary to one another. If a portion of a DNA strand reads ATCCGGAAT, then what would be the complement to this portion of DNA?
TACGGCTTA
ATCCGGAAT
TAGGCCTTA
ATGGCCAAT
