However, in the context of molecular biology, 45S refers to the precursor of ribosomal RNA, which is a crucial component of the ribosome, the cellular machinery responsible for protein synthesis. The 45S precursor is transcribed from DNA and undergoes several processing steps, including cleavage and modification, to generate mature rRNAs. The “big holes” you mentioned may refer to the nucleolar organizer regions (NORs) on chromosomes that contain multiple copies of the 45S gene.
These regions appear as large gaps or spaces in the chromatin structure and are easily visible under a microscope. The reason for the size of these holes is related to the
Why is the hole bigger on 45s?
With a bigger hole, the abrupt rotational forces could be spread out over a wider area, measuring approximately 4.712 inches (π x 1.5), which resulted in less wear and tear and a longer-lasting round hole. This was particularly crucial for the jukebox sector.
Why do some 45s have a small hole?
It’s interesting to note that 45 RPM records, a popular format for music in the mid-20th century, had different types of holes in the center. Some had a small hole that fit directly onto the record player, while others had a larger hole that required a plastic insert to stay in place. This variation in hole size was likely due to different manufacturing processes or preferences of record companies. Regardless of the hole size, 45s were a beloved format for music enthusiasts and collectors alike.
Why do people hole punch records?
“`When you see items with cut-outs or hole punches on their labels, they are most likely discounted or given away as freebies. These are essentially leftovers that stores cannot sell as new due to the damage on the packaging. However, this doesn’t mean that the product inside is damaged or expired. In fact, it’s a great opportunity to score a deal on items that are still in good condition.
So next time you see a product with a cut-out or hole punch, don’t hesitate to grab it and enjoy the savings!“`

Why are they called 45s?
Vinyl records are typically available in three speeds: 33, 45, and 78 RPM, which stands for revolutions per minute. These speeds refer to how fast the record spins on the turntable. Interestingly, the records are often identified by their speed, with 33 RPM records being referred to as “LPs” or long-playing records, while 45 RPM records are known as “singles.” The less common 78 RPM records were popular in the early 20th century and are now mostly used for historical or archival purposes.

Are 45s the same as 7-inch?
The term “45s” is commonly used to describe 7-inch records because they play at a speed of 45 RPM. These records are smaller than LPs and rotate much faster. Despite their limited storage capacity, the faster RPM results in better sound quality. However, due to the limited space, only a few minutes of audio can be recorded on each side of the record.
Why are 45s better than 33s?
In brief, there is a difference between the 33 and 45 vinyl record sizes. DJs tend to prefer the 45 RPM version because it travels faster than the 33 record size format. The larger size of the 45 allows for more waveforms to be packed into the format, resulting in more bumps and grooves. This ultimately leads to a better audio quality.
Are old records worth anything without the cover?
If the cover is missing, the value of the album would significantly decrease to only 5% of its original value, assuming it is in good condition. This deduction applies to most albums, unless it is an exceptionally rare edition. However, for old 78 records of popular bands or singers, it may be acceptable to not have the paper jacket and still retain some value.
How do I know if my 45 records are valuable?
If you’re looking to determine the value of a record, there are a few things to keep in mind. Specifically, you’ll want to look for rock and roll and R&B 45s and EPs that come with their original sleeves, or first pressings of albums. In particular, 45s with picture sleeves that were pressed in the 1950s tend to be quite valuable, with a minimum value of $10 and many being worth more than $100.
