They are called elements (:
Answer:
If the string of beads refer to a chromosome, then each bead is a gene responsible for one or more traits.
If the string of beads refer to a gene, then each bead refers to the sequence of nitrogenous bases in one strand of the gene.
Explanation:
A chromosome is composed of several genes.
A gene is composed of several nucleotides each containing a nitrogenous base. A gene is primarily made functional by the sequence of nitrogenous bases in its structure. If AGATTCA is a hypothetical sequence of the nitrogenous bases on one strand of a hypothetical gene then TCTAAGT will be the sequence of nitrogenous bases on the complementary strand of that particular gene.
If producers were removed from an ecosystem eventually all organisms would die because they all rely on the producers for food and energy
Hello there.
Question: <span>What is the general name for the first species to grow after a volcanic eruption covers an area with lava?
Answer: </span>The general name would be Primary Succession.Lava is a really hot substance that destroys most things.It comes out of the ground during a volcanic eruption.
In short, Your answer is Primary Succession.
Hope This Helps You!
Good Luck Studying ^-^
Answer:
uhhhhhhh erm have a good day is the answer yep mhm
Explanation:
A transcriptional activator is a protein (transcription factor) that increases transcription of a gene or set of genes. Activators are considered to have positive control over gene expression, as they function to promote gene transcription and, in some cases, are required for the transcription of genes to occur. Most activators are DNA-binding proteins that bind to enhancers or promoter-proximal elements.The DNA site bound by the activator is referred to as an "activator-binding site". The part of the activator that makes protein–protein interactions with the general transcription machinery is referred to as an "activating region" or "activation domain".
Most activators function by binding sequence-specifically to a regulatory DNA site located near a promoter and making protein–protein interactions with the general transcription machinery (RNA polymerase and general transcription factors), thereby facilitating the binding of the general transcription machinery to the promoter.Other activators help promote gene transcription by triggering RNA polymerase to release from the promoter and proceed along the DNA. At times, RNA polymerase can pause shortly after leaving the promoter; activators also function to allow these “stalled” RNA polymerases to continue transcription.
The activity of activators can be regulated. Some activators have an allosteric site and can only function when a certain molecule binds to this site, essentially turning the activator on Post-translational modifications to activators can also regulate activity, increasing or decreasing activity depending on the type of modification and activator being modified.
In some cells, usually eukaryotes, multiple activators can bind to the binding-site; these activators tend to bind cooperatively and interact synergistically.
