BIO. 1ST SEM REV-Cell Cycle and DNA Replication Flashcard

Front

What are the base pairing rules in DNA?

Back

Adenine (A) pairs with Thymine (T) and Guanine (G) pairs with Cytosine (C).

Front

How is the complementary strand of DNA represented for the sequence 5’ TACATGTGGCCACT 3’?

Back

3’ ATGTACCACCGTGA 5’.

Front

Which base is not found in DNA?

Back

Adenine (A) is found in DNA, but Uracil (U) is not.

Front

What is the structure of DNA as discovered by Watson and Crick?

Back

DNA is double stranded and twisted, with bases bonded to one another.

Front

What is the amino acid sequence translated from the mRNA sequence 5' UGC UAC AGA ACC 3'?

Back

Cysteine - Tyrosine - Arginine - Threonine.

Front

What is the role of DNA in cells?

Back

DNA stores genetic information and provides instructions for protein synthesis.

Front

What is the process of DNA replication?

Back

DNA replication is the process by which a cell makes an identical copy of its DNA before cell division.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the significance of Rosalind Franklin's work?

Back

Rosalind Franklin's X-ray diffraction images were crucial in understanding the double helix structure of DNA.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.
