What is a megabase of DNA?
unit of length for DNA fragments equal to 1 million nucleotides and roughly equal to 1 cM.
What is a picogram of DNA?
It is typically measured in terms of mass in picograms (trillionths (10−12) of a gram, abbreviated pg) or less frequently in daltons, or as the total number of nucleotide base pairs, usually in megabases (millions of base pairs, abbreviated Mb or Mbp). One picogram is equal to 978 megabases.
How many bases are in a megabase?
One million bases
One million bases or base pairs (1,000,000 b or 1,000,000 bp). In molecular biology, commonly used to describe the length of a DNA/RNA molecule.
What is complementary base pairing in DNA?
Explanation: The four nitrogenous bases of DNA are thymine, adenine, guanine, and cytosine. Guanine and cytosine are bound together by three hydrogen bonds; whereas, adenine and thymine are bound together by two hydrogen bonds. This is known as complementary base pairing.
What is BP in virus terms?
Genome size refers to the amount of DNA contained in a haploid genome expressed either in terms of the number of base pairs, kilobases (1 kb = 1000 bp), or megabases (1 Mb = 1 000 000 bp), or as the mass of DNA in picograms (1 pg = 10−12 g). Genome sizes of bacteriophages and viruses range from about 2 kb to over 1 Mb.
How long is a megabase pair?
one million base pairs
A megabase pair (Mbp) is a unit of length of nucleic acids, equal to one million base pairs or to one thousand kilobase pairs.
What is a picogram?
: one trillionth of a gram.
What is the paradox in C value paradox?
The C value paradox is that the amount of DNA in a haploid genome (the 1C value) does not seem to correspond strongly to the complexity of an organism, and 1C values can be extremely variable.
How many kilobases are in A megabase?
How many Kilobase Pairs are in a Megabase Pair? The answer is one Megabase Pair is equal to 1000 Kilobase Pairs.
How long is A megabase pair?
What does uracil pair with?
adenine
During the synthesis of an RNA strand from a DNA template (transcription), uracil pairs only with adenine, and guanine pairs only with cytosine.
Why are DNA bases complementary?
The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The hydrogen bonding between complementary bases holds the two strands of DNA together.
Which is the best definition of a megabase?
1. One million paired nucleotides in a DNA sequence. 2. One million unpaired nucleotides in a single-stranded nucleic acid sequence. 3. Informally, any very large fragment of DNA. A unit of measurement of the length of a segment of DNA equal to 1,000,000 base pairs. Usually contracted to Mb. DNA or RNA of length 106 bases.
How many base pairs are in a megabase?
A unit of measurement of the length of a segment of DNA equal to 1,000,000 base pairs. Usually contracted to Mb. Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005
How many megabases are in a bacterium’s genome?
In contrast, a bacterium’s genome typically comprises 1 to 4 million base pairs, or megabases (Mb), of DNA, almost all of which encode genes.
