What is mRNA synthesis is called?
The process of making mRNA from DNA is called transcription, and it occurs in the nucleus. The message is encoded in the nucleotide sequence of the mRNA, which is complementary to the nucleotide sequence of the DNA that served as a template for synthesizing the mRNA. Making proteins from mRNA is called translation.
What is the human genome in simple terms?
Human genome: All the genetic information in a person. The human genome is made up of the DNA in chromosomes as well as the DNA in mitochondria.
What is the smallest human gene?
Chromosome 21
Chromosome 21 is both the smallest human autosome and chromosome, with 48 million base pairs (the building material of DNA) representing about 1.5 percent of the total DNA in cells….

How many nucleotides are in a chromosome?
Each chromosome contains a single very long, linear DNA molecule. In the smallest human chromosomes this DNA molecule is composed of about 50 million nucleotide pairs; the largest chromosomes contain some 250 million nucleotide pairs.
How is mRNA synthesized?
mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
What is RNA made of?
Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U).
What do genomes do?
A genome is the complete set of genetic information in an organism. It provides all of the information the organism requires to function. In living organisms, the genome is stored in long molecules of DNA called chromosomes. There are 23 pairs of chromosomes in the human genome.
Is Down Syndrome one extra chromosome?
Typically, a baby is born with 46 chromosomes. Babies with Down syndrome have an extra copy of one of these chromosomes, chromosome 21. A medical term for having an extra copy of a chromosome is ‘trisomy. ‘ Down syndrome is also referred to as Trisomy 21.
What are the 4 types of nucleotides?
DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). The nucleotides attach to each other (A with T, and G with C) to form chemical bonds called base pairs, which connect the two DNA strands.
What are these 4 nucleotides?
Because there are four naturally occurring nitrogenous bases, there are four different types of DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).
How does a DNS query leave a trace?
Just as when you browse the internet, whether pivoting from a search engine result or directly accessing a website URL, your DNS queries also leave a trace. How much of a trace depends on the systems and processes involved along the way, from the query leaving the operating system, to receiving the resultant IP address.
How are TXT types used in DNS tunneling?
TXT types were designed to provide descriptive text, such as service details, contact names, phone numbers, etc in response to TXT DNS queries for domain names. Guess what looks likes text?
What does noerror mean on a DNS request?
Enter NOERROR. NOERROR, as the term suggests means everything worked fine – your request was processed and an answer awaits you. With a NOERROR comes a response that can be processed. Usually this is the IPv4 (for A type requests) or IPv6 (for AAAA type requests) or it could be TXT]
How is the ubiquity of DNS a good thing?
DNS’ ubiquity (and frequent lack of scrutiny) can enable very elegant and subtle methods for communicating, and sharing data, beyond the protocol’s original intentions.
