Unlike DNA replication, in which both strands are copied, only one strand is transcribed. The strand that contains the gene is called the sense strand, while the complementary strand is the antisense strand. What is a single strand of DNA called? In both cases, replication occurs so quickly because multipleRead More →
A gene is a small section of DNA? that contains the instructions for a specific molecule, usually a protein?. The purpose of genes? is to store information. Each gene contains the information required to build specific proteins needed in an organism. What is difference between DNA and chromosome? A chromosomeRead More →
Phospholipids, proteins and enzymes. Which organelle has its own DNA? Chloroplasts and mitochondria are subcellular bioenergetic organelles with their own genomes and genetic systems. Which organelle does not contain DNA? Ribosomes are cell organelles that lack a film. Ribosomes do not contain any DNA. Hence, option C- Ribosome is theRead More →
The double helix describes the appearance of double-stranded DNA, which is composed of two linear strands that run opposite to each other, or anti-parallel, and twist together. Each DNA strand within the double helix is a long, linear molecule made of smaller units called nucleotides that form a chain. WhatRead More →
As these cells lack a nucleus they do not contain a copy of the genome. When extracting DNA for a genomic or genetic test it needs to come from nucleated cells. Which cells are non nucleated? Cells that lack a nucleus are known as non-nucleated cells. … Erythrocytes (red bloodRead More →
Single stranded DNA can hybridize with another DNA or an RNA with complementary base pairing. Can RNA be hybridized? Hybridization is the process of combining two complementary single-stranded DNA or RNA molecules and allowing them to form a single double-stranded molecule through base pairing.Read More →
DNA, short for deoxyribonucleic acid, is the molecule that contains the genetic code of organisms. This includes animals, plants, protists, archaea and bacteria. DNA is in each cell in the organism and tells cells what proteins to make. … They do not code for protein sequences. What is deoxyribonucleic acidRead More →
Both DNA and RNA are built with a sugar backbone, but whereas the sugar in DNA is called deoxyribose (left in image), the sugar in RNA is called simply ribose (right in image). Where is the deoxyribose in DNA? The sugars in the backbone The backbone of DNA is basedRead More →
