A RNA-restricting repressor ties to the mRNA and forestalls interpretation of the mRNA into protein. This hindering of articulation is called repression.
Transcribing a gene, RNA polymerase ties to the DNA of the quality at an area called the promoter.
It contains acknowledgment locales for RNA polymerase or its aide proteins to tie to.
The DNA opens up in the advertiser district with the goal that RNA <em>polymerase can start translation. </em>
Interpretation factors are an exceptionally assorted group of proteins and by and large capacity in multi-subunit protein edifices.
They may tie legitimately to <em>uncommon “promoter” locales of DNA, </em>which lie upstream of the coding area in a <em>quality, or straightforwardly to the RNA polymerase atom.</em>

What occurs when the heads of myosin contact actin?

Elza [17]

When myosin head bind to the actin, it will form a cross bridge and causes a power stroke to occur. It will hydrolyse the ATP to ADP + Pi in the ATPase of the myosin head and the myosin head will detached from actin and tilt back to its original position. Hence the sarcomere will shorten

pshichka [43]

1. The group nearest the end or with the shortest stem of a phylogenetic tree has evolved most recently. In this case it is eutherians.

2. The group with the longest stem has been around the longest: fish

3. A direct common ancestor will share the same immediate line, like marsupials and eutherians. Fish and marsupials do not have a common direct ancestor.

lapo4ka [179]

Answer: The systems regulate the house, the same way our body system helps regulate our body. If it wasn’t for the electrical system, plumbing system, heating, and cooling system the house wouldn’t be regulated or able to live in. Just like if our bodies isn’t being regulated, we can't live.

I hope this could help you! ^^
