What is a picogram of DNA?

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.

What is C-value in DNA?

The DNA amount in the unreplicated gametic nucleus of an organism is referred to as its C-value, irrespective of the ploidy level of the taxon.

Why C-value of DNA is 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.

What is the C Paradox and why is it said to be a paradox?

The so-called C-Value Paradox refers to the observation that genome size does not uniformly increase with respect to perceived complexity of organisms, for example vertebrate with respect to invertebrate animals, or “lower” versus “higher” vertebrate animals (red box).

What is picogram used to measure?

The picogram (pg) is a unit of mass in the International System of Units, defined as 10-15 kilogram using the SI prefix system.

What is a haploid genome?

Haploid refers to the presence of a single set of chromosomes in an organism’s cells. Sexually reproducing organisms are diploid (having two sets of chromosomes, one from each parent). In humans, only the egg and sperm cells are haploid.

What does 2n 4c mean?

2n 4c Two homolog chromosomes (diploid) consisting each of two sister chromatids (two yellow and two blue), thus 4c in total.

What is the difference between C-value paradox and G value paradox?

The apparent disconnect between the number of genes in a species and its biological complexity was dubbed the G-value paradox. While the C-value paradox unraveled with the discovery of massive sequences of noncoding DNA, resolution of the G-value paradox appears to rest on differences in genome productivity.

What is the difference between pg mL and ng dL?

You can convert pg/mL to ng/dL as we know many internet resources discuss free testosterone levels as ng/dL. The conversion factor is simply a division of your result by 10 (if your result was 100 pg/mL then that becomes 10 ng/dL).

How many Haploids do humans have?

The genomes of normal diploid human cells consist of 23 maternal chromosomes and 23 paternal chromosomes. By definition, haploid human cells harbor only one of these parental sets, and are thus considered uniparental.

What is an unreplicated chromosome?

An unreplicated chromosome contains one double strand -DNA molecule. A replicated chromosome contains two identical double strand -DNA- molecules, the chromatids, that are joined at their centromere.

What is the meaning of 4C DNA?

When this cell undergoes mitotic division, metaphase chromosomes are maximally compact and have duplicated their DNA (4C), however the two DNA strands (chromatids) remain attached to a single centromere.

What is pg per mL?

Some medical tests report results in picograms per milliliter (pg/mL). A picogram is one-trillionth of a gram. A gram is about 1/30 of an ounce. A milliliter measures fluid volume equal to one-thousandth of a liter.

How many Ng are in pg mL?

pg/mL↔ng/ml 1 ng/ml = 1000 pg/mL.

Is a genome 23 or 46 chromosomes?

In reproduction, the egg and sperm cells fuse into a single cell. This single cell will then contain two genomes in 46 chromosomes or 23 pairs, i.e., two haploid sets of chromosomes.
